Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock
The Fund pays transaction costs, such as commissions or spreads, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in the Total Annual Fund Operating Expenses or in the Example, affect the Fund’s performance.
During the most recent fiscal year, the Fund’s portfolio turnover rate was 130.57% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
Under normal market conditions, the Fund will invest at least 80% of its net assets (plus any borrowings for investment purposes) in fixed income securities and loans issued by companies that are rated below investment grade (i.e., “junk” bonds and loans). The fixed income securities and loans in which the Fund invests include traditional corporate bonds, zero-coupon bonds, commercial paper, exchange-traded notes (“ETNs”), distressed debt securities (i.e., fixed income securities that are near to going into default), bank loan assignments and/or participations, private placements, mortgage- and asset-backed securities, U.S. Government obligations, sovereign debt and bank loans to corporate borrowers, and may have fixed, floating or variable rates. The Fund typically focuses on instruments that have short durations (i.e., have an expected duration of three years or less from the time of purchase through maturity, call, or corporate action). To the extent the Fund invests in other investment companies, including exchange-traded funds (“ETFs”), the Fund will consider the underlying holdings of such funds for purposes of meeting its policy of investing at least 80% of its net assets in fixed income securities and loans of companies that have been rated below investment grade.
The Fund may invest up to 35% of its total assets in foreign fixed income instruments, including those denominated in U.S. dollars or other currencies, and may also invest without limit in Rule 144A fixed income securities. Additionally, the Fund may invest up to 25% of its total assets in convertible bonds, up to 25% of its total assets in Yankee bonds, and up to 20% in preferred stocks, special purpose acquisition companies (“SPACs”), and income producing equities. The Fund’s investments in derivative instruments, specifically futures contracts, options, options on futures contracts, swap agreements and forward currency contracts (collectively, “Derivatives”), may be used as a substitute for making direct investments in the underlying instruments or to reduce exposure to, or “hedge” against, market volatilities and other risks. The Fund may use a Derivative rather than investing directly in an underlying asset class as a low-cost, effective means to gain exposure to such asset class.
The Fund will sell an investment during portfolio rebalancing periods when the Fund’s holdings in that investment are larger than the allocation suggested by the Adviser’s investment models or when a more attractive investment becomes available. The Adviser may engage in active trading of the Fund’s portfolio investments, resulting in a high portfolio turnover rate, to achieve the Fund’s investment objective.
There is no assurance the Fund will achieve its investment objective.

CrossingBridge Low Duration High Yield Fund | Asset-Backed And Mortgage-Backed Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock
Asset-Backed and Mortgage-Backed Securities Risk. Asset-backed and mortgage-backed securities are subject to risk of prepayment. These types of securities may also decline in value because of mortgage foreclosures or defaults on the underlying obligations. Asset-backed and mortgage-backed securities are also subject to extension risk, the risk that rising interest rates could cause prepayments to decrease, extending the life of asset-backed and mortgage-backed securities with lower payment rates.
CrossingBridge Low Duration High Yield Fund | Bank Loans Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock
Bank Loans Risk. The Fund’s investments in secured and unsecured assignments and/or participations in bank loans may create substantial risk. In making investments in such loans, which are made by banks or other financial intermediaries to borrowers, the Fund will depend primarily upon the creditworthiness of the borrower for payment of principal and interest. As a result, sale proceeds related to the sale of loans may not be available to make additional investments or to meet the Fund’s redemption obligations until potentially a substantial period after the sale of the loans. The Fund, therefore, may be forced to sell other assets at a loss to pay redemption proceeds. A significant portion of bank loans may be “covenant lite” loans that may contain fewer or less restrictive constraints on the borrower and fewer or no financial maintenance covenants and restrictions. A covenant lite loan typically contains fewer clauses which allow an investor to proactively enforce financial covenants. Covenant lite loans also generally provide fewer investor protections if certain criteria are breached. The Fund may experience losses or delays in enforcing its rights on its holdings of covenant lite loans. The secondary market for bank loans is a private, unregulated inter-dealer or inter-bank resale market. Purchases and sales of loans are generally subject to contractual restrictions that must be satisfied before a loan can be bought or sold. These restrictions may impede the Fund’s ability to buy or sell loans and may negatively impact the transaction price. It may take longer than seven days for transactions in loans to settle. The Fund may hold cash, sell investments or temporarily borrow from banks to meet short-term liquidity needs due to the extended loan settlement process, such as to satisfy redemption requests from Fund shareholders. U.S. federal securities laws afford certain protections against fraud and misrepresentation in connection with the offering or sale of a security, as well as against manipulation of trading markets for securities. The typical practice of a lender in relying exclusively or primarily on reports from the borrower may involve the risk of fraud, misrepresentation, or market manipulation by the borrower. It is unclear whether U.S. federal securities law protections are available to an investment in a loan. In certain circumstances, loans may not be deemed to be securities, and in the event of fraud or misrepresentation by a borrower, lenders may not have the protection of the anti-fraud provisions of the federal securities laws. However, contractual provisions in the loan documents may offer some protections, and lenders may also avail themselves of common-law fraud protections under applicable state law.
CrossingBridge Low Duration High Yield Fund | Below Investment Grade Securities Risk (Commonly Referred To As “Junk” Bonds) Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock
Below Investment Grade Securities Risks (commonly referred to as “junk” bonds). The Fund may invest 100% of its assets in fixed-income instruments that are or are deemed to be the equivalent in terms of quality to securities rated below investment grade by nationally recognized statistical rating agencies and accordingly involve great risk. Such securities are regarded as predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal in accordance with the terms of the obligations and involve major risk to adverse conditions. These securities offer higher returns than bonds with higher ratings as compensation for holding an obligation of an issuer perceived to be less creditworthy. The market prices of such securities are also subject to abrupt and erratic market movements and above-average price volatility, and the spread between the bid and ask prices of such securities may be greater than those prevailing in other securities markets. Changes in economic conditions or developments regarding issuers of non-investment grade debt securities are more likely to cause price volatility and weaken the capacity of such issuers to make principal and interest payments than is the case for higher grade debt securities. In addition, the market for lower grade debt securities may be thinner and less active than for higher grade debt securities.
CrossingBridge Low Duration High Yield Fund | Convertible Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock
Convertible Securities Risk. A convertible security is a fixed-income security (a debt instrument or a preferred stock) which may be converted at a stated price within a specified period of time into a certain quantity of the common stock of the same or a different issuer. The market value of a convertible security performs like that of a regular debt security, that is, if market interest rates rise, the value of the convertible security falls.
CrossingBridge Low Duration High Yield Fund | Corporate Events Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock
Corporate Events Risk. Corporate events risk is the risk that a corporate transaction or opportunity will not occur, or a natural disaster or regulatory change will cause an abrupt downgrade in a corporate bond which may lower the Fund’s performance.
CrossingBridge Low Duration High Yield Fund | Counterparty Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock
Counterparty Risk. Counterparty risk arises upon entering into borrowing arrangements or Derivative transactions and is the risk from the potential inability of counterparties to meet the terms of their contracts.
CrossingBridge Low Duration High Yield Fund | Credit-Related Instruments Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock
Credit-Related Instruments Risk. Interest rates may go up resulting in a decrease in the value of the securities held by the Fund. Interest rates have been rising from historically low levels, so the Fund faces a heightened risk that interest rates may continue to rise. A credit rating assigned to a particular debt security is essentially the opinion of an NRSRO as to the credit quality of an issuer and may prove to be inaccurate. There is also the risk that a bond issuer may “call,” or repay, its high yielding bonds before their maturity dates. Debt securities subject to prepayment can offer less potential for gains during a declining interest rate environment and similar or greater potential for loss in a rising interest rate environment. Limited trading opportunities for certain fixed income securities may make it more difficult to sell or buy a security at a favorable price or time, particularly during periods of market turmoil, and may also make these securities difficult to value.
CrossingBridge Low Duration High Yield Fund | Credit Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock
Credit Risk. Debt portfolios are subject to credit risk. Credit risk refers to the likelihood that an issuer will default in the payment of principal and/or interest on an instrument. Financial strength and solvency of an issuer are the primary factors influencing credit risk. In addition, lack or inadequacy of collateral or credit enhancement for a debt instrument may affect its credit risk. Credit risk may change over the life of an instrument, and debt obligations which are rated by rating agencies are often reviewed and may be subject to downgrade.
CrossingBridge Low Duration High Yield Fund | Cybersecurity Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock
Cybersecurity Risk. With the increased use of technologies such as the Internet to conduct business, the Fund is susceptible to operational, information security, and related risks. Cyber incidents affecting the Fund or its service providers have the ability to cause disruptions and impact business operations, potentially resulting in financial losses, interference with the Fund’s ability to calculate its NAV, impediments to trading, the inability of shareholders to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs.
CrossingBridge Low Duration High Yield Fund | Derivatives Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock
Derivatives Risk. The Fund’s use of swap contracts, interest rate futures and options on interest rate futures involves risks different from, or possibly greater than the risks associated with investing directly in securities including leverage risk, tracking risk and counterparty default risk. Option positions may expire worthless exposing the Fund to potentially significant losses. To the extent the Fund invests in Derivatives, the risks below may affect its performance:
Interest Rate Risk. Underlying investments may lose value due to interest rate changes.
Liquidity Risk. The Fund may not be able to sell or close out a Derivative instrument.
Options and Futures Risk. Options and futures contracts may be more volatile than investments directly in the underlying securities, involve additional costs and may involve a small initial investment relative to the risk assumed.
Swap Agreements Risk. A swap contract may not be assigned without the consent of the counterparty, and may result in losses in the event of a default or bankruptcy of the counterparty.

CrossingBridge Low Duration High Yield Fund | Distressed Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock
Distressed Securities Risk. The Fund may invest in securities of companies that are experiencing significant financial or business difficulties, including companies involved in bankruptcy or other reorganization and liquidation proceedings. Although such investments may result in significant returns to the Fund, they involve a substantial degree of risk. Any one or all of the issuers of the securities in which the Fund may invest may be unsuccessful or not show any return for a considerable period of time. The level of analytical sophistication, both financial and legal, necessary for successful investment in companies experiencing significant business and financial difficulties is unusually high. There is no assurance that the Adviser will correctly evaluate the value of the assets collateralizing the Fund’s loans or the prospects for a successful reorganization or similar action. In any reorganization or liquidation proceeding relating to a company in which the Fund invests, the Fund may lose its entire investment or may be required to accept cash or securities with a value less than the Fund’s original investment. Under such circumstances, the returns generated from the Fund’s investments in distressed securities may not adequately compensate for the risks assumed. In addition, there is no minimum credit standard that is a prerequisite to the Fund’s investment in any instrument, and a significant portion of the obligations and preferred stock in which the Fund invests may be less than investment grade.
CrossingBridge Low Duration High Yield Fund | Equity Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock
Equity Securities Risk. The Fund may invest in income producing equity securities. Although investments in income producing equity securities are considered safer than equity securities in general, and equities historically have been a leading choice for long-term investors, the values of stocks rise and fall depending on many factors. The stock or other security of a company may not perform as well as expected, and may decrease in value, because of factors related to the company (such as poorer than expected earnings or certain management decisions) or to the industry in which the company is engaged (such as a reduction in the demand for products or services in a particular industry). Market and economic factors may adversely affect securities markets generally, which could in turn adversely affect the value of the Fund’s investments, regardless of the performance or expected performance of companies in which the Fund invests.
CrossingBridge Low Duration High Yield Fund | Exchange-Traded Note Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock
Exchange-Traded Note Risk. The value of an ETN may be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in the underlying securities markets, changes in the applicable interest rates, changes in the issuer’s credit rating and economic, legal, political or geographic events that affect the referenced index. In addition, the notes issued by ETNs and held by the Fund are unsecured debt of the issuer.
CrossingBridge Low Duration High Yield Fund | Fixed Income Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock
Fixed Income Securities Risk. The Fund invests a significant portion of its assets in fixed income securities. Fixed income securities are subject to credit risk and market risk, including interest rate risk. Credit risk is the risk of the issuer’s inability to meet its principal and interest payment obligations. Market risk is the risk of price volatility due to such factors as interest rate sensitivity, market perception of the creditworthiness of the issuer and general market liquidity. There is no limitation on the maturities of fixed income securities in which the Fund invests. Securities having longer maturities generally involve greater risk of fluctuations in value resulting from changes in interest rates.
CrossingBridge Low Duration High Yield Fund | Fixed Income Securities Market Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock
Fixed Income Securities Market Risk. Difficult conditions in the broader financial markets have in the past resulted in a temporary but significant contraction in liquidity for fixed income securities. Liquidity relates to the ability of the Fund to sell its investments in a timely manner at a price approximately equal to its value on the Fund’s books. To the extent that the market for fixed income securities suffers such a contraction, securities that were considered liquid at the time of investment could become temporarily illiquid, and the Adviser may experience delays or difficulty in selling assets at the prices at which the Fund carries such assets, which may result in a loss to the Fund. There is no way to predict reliably when such market conditions could re-occur or how long such conditions could persist.
In the event of a severe market contraction precipitated by general market turmoil, economic conditions, changes in prevailing interest rates or otherwise, coupled with extraordinary levels of Fund shareholder redemption requests, the Fund may have to consider selling its holdings at a loss including at prices below the current value on the Fund’s books, borrowing money to satisfy redemption requests in accordance with the Fund’s borrowing policy or postponing payment of redemption requests for up to seven days or longer, as permitted by applicable law, or other extraordinary measures. In addition, if the Fund needed to sell large blocks of investments to meet shareholder redemption requests or to raise cash, those sales could further reduce prices, particularly for lower-rated and unrated securities.
In response to rising inflation, the Federal Reserve began raising short-term interest rates in 2022 with the potential for further rate increases. Uncertainty regarding the ability of the Federal Reserve to successfully control inflation, the potential for incremental rate increases, and the full impact of prior rate increases may negatively impact fixed income security prices and increase market volatility. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities.
CrossingBridge Low Duration High Yield Fund | Floating Rate Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock
Floating Rate Risk. Securities with floating interest rates generally are less sensitive to interest rate changes but may decline in value if their interest rates do not rise as much, or as quickly, as interest rates in general. Conversely, floating rate instruments will not generally increase in value if interest rates decline. Changes in interest rates will also affect the amount of interest income the Fund earns on its floating rate investments.
CrossingBridge Low Duration High Yield Fund | Foreign Investments Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock
Foreign Investments Risk. Investments in fixed income securities of U.S. and foreign issuers and instruments that are linked to fixed income securities (collectively, “Credit-Related Instruments”) involve certain risks not generally associated with investments in the securities of U.S. issuers, including changes in currency exchange rates, unstable political, social and economic conditions, a lack of adequate or accurate company information, differences in the way securities markets operate, less secure international banks or securities depositories than those in the U.S. and foreign controls on investment. In addition, individual international country economies may differ favorably or unfavorably from the U.S. economy in such respects as growth of gross domestic product, rates of inflation, capital reinvestment, resources, self-sufficiency and balance of payments position. Income earned on foreign investments may be subject to foreign withholding taxes.
CrossingBridge Low Duration High Yield Fund | Forward Currency Contracts Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock
Forward Currency Contracts. The Fund may enter into forward currency contracts. A forward currency contract is an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days from the date of the contract agreed upon by the parties, at a price set at the time of the contract. For example, the Fund might purchase a particular currency or enter into a forward currency contract to preserve the U.S. dollar price of securities it intends to or has contracted to purchase. Alternatively, it might sell a particular currency on either a spot or forward basis to hedge against an anticipated decline in the dollar value of securities it intends to or has contracted to sell. Although this strategy could minimize the risk of loss due to a decline in the value of the hedged currency, it could also limit any potential gain from an increase in the value of the currency.
CrossingBridge Low Duration High Yield Fund | General Market Risk Member

Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock
Government Securities Risk. The Fund invests in securities issued or guaranteed by the U.S. Government, its agencies and instrumentalities (including government-sponsored enterprises). Securities issued by
agencies and instrumentalities may not be guaranteed or insured by the U.S. Government and may only be supported by the credit of the issuing entity.
CrossingBridge Low Duration High Yield Fund | High Portfolio Turnover Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock
High Portfolio Turnover Risk. The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Fund’s performance.
CrossingBridge Low Duration High Yield Fund | Interest Rate Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock
Interest Rate Risk. The prices of securities in general and fixed-income securities in particular tend to be sensitive to interest rate fluctuations. Increases in interest rates can result in significant declines in the prices of fixed-income securities. Securities with floating interest rates generally are less sensitive to interest rate changes but may decline in value if their interest rates do not rise as much, or as quickly, as interest rates in general. The negative impact on fixed income securities generally from rate increases, regardless of the cause, could be swift and significant, which could result in losses by the Fund, even if anticipated by the Adviser. Starting in 2022, the Federal Reserve began to increase interest rates in an effort to combat inflation which has resulted in periods of volatility.
CrossingBridge Low Duration High Yield Fund | Leverage Risk Member

CrossingBridge Low Duration High Yield Fund | Other Investment Company And Exchange-Traded Fund Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock
Other Investment Company and Exchange-Traded Fund Risk. When the Fund invests in other investment companies, including closed-end funds and ETFs, it will bear additional expenses based on its pro rata share of the other investment company’s operating expenses, including the potential duplication of management fees. The risk of owning another investment company generally reflects the risks of owning the underlying investments the other investment company holds. The Fund also will incur brokerage costs when it purchases and sells investment company shares, ETFs may trade at a discount or premium to NAV. There can be no assurance that an active trading market for an ETF’s shares will exist. Shares of closed-end funds frequently trade at a price per share that is less than the net asset value (“NAV”) per share. There can be no assurance that the market discount on shares of any closed-end fund purchased by the Fund will ever decrease or that when the Fund seeks to sell shares of a closed-end fund, it can receive the NAV of those shares. There are greater risks involved in investing in securities with limited market liquidity.
CrossingBridge Low Duration High Yield Fund | Preferred Stock Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock
Preferred Stock Risk. Preferred stocks may be more volatile than fixed income securities and are more correlated with the issuer’s underlying common stock than fixed income securities. Additionally, the dividend on a preferred stock may be changed or omitted by the issuer, and participation in the growth of an issuer may be limited.
CrossingBridge Low Duration High Yield Fund | Prepayment Risk Member

U.S. and international markets have experienced and may continue to experience significant periods of volatility in recent years and months due to a number of economic, political and global macro factors including uncertainty regarding inflation and central banks’ interest rate increases, the possibility of a national or global recession, trade tensions, political events, the war between Russia and Ukraine, significant conflict between Israel and Hamas in the Middle East, and the impact of the coronavirus (COVID-19) global pandemic. The impact of COVID-19 may last for an extended period of time. As a result of continuing political tensions and armed conflicts, including the war between Ukraine and Russia, the U.S. and the European Union imposed sanctions on certain Russian individuals and companies, including certain financial institutions, and have limited certain exports and imports to and from Russia. The war has contributed to recent market volatility and may continue to do so. Continuing market volatility as a result of recent market conditions or other events may have an adverse effect on the performance of the Fund.

Risk Narrative [Text Block] rr_RiskTextBlock
Rule 144A Securities Risk. The market for Rule 144A securities typically is less active than the market for publicly-traded securities. Rule 144A securities carry the risk that the liquidity of these securities may become impaired, making it more difficult for the Fund to sell these securities.
CrossingBridge Low Duration High Yield Fund | Sovereign Debt Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock
Sovereign Debt Risk. The Fund may invest in securities issued or guaranteed by foreign governmental entities (known as sovereign debt securities). These investments are subject to the risk of payment delays or defaults, due, for example, to cash flow problems, insufficient foreign currency reserves, political considerations, large debt positions relative to the country’s economy, or failure to implement economic reforms. There is no legal or bankruptcy process for collecting sovereign debt.
CrossingBridge Low Duration High Yield Fund | SPACs Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock SPACs Risk. The Fund invests in equity securities of SPACs, which raise assets to seek potential business combination opportunities. Unless and until a business combination is completed, a SPAC generally invests its assets in U.S. government securities, money market securities, and cash. Because SPACs have no operating history or ongoing business other than seeking a business combination, the value of their securities is particularly dependent on the ability of the entity’s management to identify and complete a profitable business combination. There is no guarantee that the SPACs in which the Fund invests will complete a business combination or that any business combination that is completed will be profitable. The market perception of a SPAC’s ability to complete a business combination could materially impact the market value of the SPAC’s securities. Public stockholders of SPACs may not be afforded a meaningful opportunity to vote on a proposed initial business combination because certain stockholders, including stockholders affiliated with the management of the SPAC, may have sufficient voting power, and a financial incentive, to approve such a transaction without support from public stockholders. As a result, a SPAC may complete a business combination even though a majority of its public stockholders do not support such a combination. Some SPACs may pursue a business combination only within certain industries or regions, which may increase the volatility of their prices.

Risk Narrative [Text Block] rr_RiskTextBlock
Tax Risk. The Fund’s investment strategies, specifically its investments in Derivatives, may subject the Fund to special tax rules, the effect of which may be to accelerate income to the Fund, defer losses to the Fund, cause adjustments in the holding periods of the Fund’s securities, convert long-term capital gains into short-term capital gains or convert short-term capital losses into long-term capital losses.
CrossingBridge Low Duration High Yield Fund | Tracking Risk Member

Tracking Risk. The value of the Derivative instruments the Fund uses may not correlate to (or track) the values of the underlying securities. When used for hedging purposes, lack of correlation between price or
rate movements of the Derivative instrument and the underlying investment sought to be hedged may prevent the Fund from achieving the intended hedging effect or expose the Fund to risk of loss.

Yankee Bond Risk. Yankee bonds are subject to the same risks as other debt issues, notably credit risk, market risk, currency and liquidity risk. Other risks include adverse political and economic developments; the extent and quality of government regulations of financial markets and institutions; the imposition of foreign withholding taxes; and the expropriation or nationalization of foreign issuers.
CrossingBridge Low Duration High Yield Fund | Zero Coupon Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock
Zero Coupon Securities Risk. While interest payments are not made on such securities, holders of such securities are deemed to have received income annually, notwithstanding that cash may not be received currently. Some of these securities may be subject to substantially greater price fluctuations during periods of changing market interest rates than are comparable securities that pay interest currently. Longer term zero coupon bonds are more exposed to interest rate risk than shorter term zero coupon bonds.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Fund seeks to offer a higher yield than cash instruments while maintaining a low duration by investing primarily in fixed income securities consistent with capital preservation. The Fund defines fixed income securities to include: bills, notes, bonds, debentures, convertible bonds, loan participations, syndicated loan assignments, mortgage- and asset-backed securities, Rule 144A fixed income securities, zero coupon securities, sovereign debt and other evidence of indebtedness issued by U.S. or foreign corporations, governments, government agencies or government instrumentalities, including floating-rate securities, preferred stock and fixed income-like equities. Convertible bonds, preferred stocks, and fixed income-like equities (e.g., special purpose acquisition companies (“SPACs”)) provide interest income and/or the potential for capital appreciation while having an effective maturity. Floating-rate securities provide interest income that can increase or decrease with interest rates. The Fund invests in individual fixed income securities without restriction as to issuer credit quality, capitalization or security maturity. Though the Fund can invest in securities domiciled in foreign countries and denominated in foreign currencies, the Fund invests primarily in securities denominated in U.S. dollars issued by issuers domiciled in developed markets. The Fund may invest up to 100% of its assets in lower-quality fixed income securities — commonly known as “high yield” or “junk” bonds. Junk bonds are generally rated lower than Baa3 by Moody’s Investors Service, Inc. (“Moody’s”) or lower than BBB- by S&P Global Ratings Services (“S&P”) (“S&P”). The Adviser believes these investments are consistent with the preservation of capital. The Fund may invest in companies that are in default, subject to bankruptcy or reorganization.
The Adviser seeks to manage interest rate, default and currency risks. The Adviser manages interest rate risk by maintaining, under normal market conditions, an average portfolio duration of 1 or less by investing in short-term, medium-term and floating rate securities. The stated maturity for a fixed income security may be longer than its expected maturity used for the portfolio duration calculation. The stated maturity may differ from the expected maturity as a result of market conditions or corporate actions (such as a change of control ‘put’ provision or corporate redemption feature). Duration is a measure of sensitivity of a security’s price to changes in interest rates. For example, a security with a duration of 1 would be expected to decrease in price 1% for every 1% rise in interest rates (the inverse is true as well).
The Adviser manages default risk by selecting securities of issuers that it believes will pay interest and principal regardless of their credit rating, based upon the Adviser’s credit analysis of each issuer. The Adviser may also select securities that are in default, subject to bankruptcy or reorganization where the
Adviser believes the risks to be consistent with capital preservation, based on the Adviser’s analysis of an issuer’s liquidation value or post-bankruptcy or post-reorganization value.
The Adviser manages foreign currency risk by investing primarily in securities denominated in U.S. dollars, such as Yankee bonds. If the Fund were to invest in foreign currency denominated securities, the Fund restricts such activity to less than 35% of the Fund’s total assets. When deemed appropriate, the Adviser may hedge the foreign currency exposure typically, and primarily, with forward currency contracts. A forward currency contract is an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days from the date of the contract agreed upon by the parties.
The Adviser may engage in active and frequent trading, resulting in a high portfolio turnover rate, to achieve the Fund’s investment objective.

There is no assurance that the Fund will achieve its investment objective.

Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Asset-Backed and Mortgage-Backed Securities Risk. Asset-backed and mortgage-backed securities are subject to risk of prepayment. These types of securities may also decline in value because of mortgage foreclosures or defaults on the underlying obligations. Asset-backed and mortgage-backed securities are also subject to extension risk, the risk that rising interest rates could cause prepayments to decrease, extending the life of asset-backed and mortgage-backed securities with lower payment rates.
CrossingBridge Ultra-Short Duration Fund | Bank Loans Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock
Bank Loans Risk. The Fund’s investments in secured and unsecured assignments and/or participations in bank loans may create substantial risk. In making investments in such loans, which are made by banks or other financial intermediaries to borrowers, the Fund will depend primarily upon the creditworthiness of the borrower for payment of principal and interest. As a result, sale proceeds related to the sale of loans may not be available to make additional investments or to meet the Fund’s redemption obligations until potentially a substantial period after the sale of the loans. The Fund, therefore, may be forced to sell other assets at a loss to pay redemption proceeds. A significant portion of bank loans may be “covenant lite” loans that may contain fewer or less restrictive constraints on the borrower and fewer or no financial maintenance covenants and restrictions. A covenant lite loan typically contains fewer clauses which allow an investor to proactively enforce financial covenants. Covenant lite loans also generally provide fewer investor protections if certain criteria are breached. The Fund may experience losses or delays in enforcing its rights on its holdings of covenant lite loans. The secondary market for bank loans is a private, unregulated inter-dealer or inter-bank resale market. Purchases and sales of loans are generally subject to contractual restrictions that must be satisfied before a loan can be bought or sold. These restrictions may impede the Fund’s ability to buy or sell loans and may negatively impact the transaction price. It may take longer than seven days for transactions in loans to settle. The Fund may hold cash, sell investments or temporarily borrow from banks to meet short-term liquidity needs due to the extended loan settlement process, such as to satisfy redemption requests from Fund shareholders. U.S. federal securities laws afford certain protections against fraud and misrepresentation in connection with the offering or sale of a security, as well as against manipulation of trading markets for securities. The typical practice of a
lender in relying exclusively or primarily on reports from the borrower may involve the risk of fraud, misrepresentation, or market manipulation by the borrower. It is unclear whether U.S. federal securities law protections are available to an investment in a loan. In certain circumstances, loans may not be deemed to be securities, and in the event of fraud or misrepresentation by a borrower, lenders may not have the protection of the anti-fraud provisions of the federal securities laws. However, contractual provisions in the loan documents may offer some protections, and lenders may also avail themselves of common-law fraud protections under applicable state law.
CrossingBridge Ultra-Short Duration Fund | Below Investment Grade Securities Risk (Commonly Referred To As “Junk” Bonds) Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Below Investment Grade Securities Risks (commonly referred to as “junk” bonds). The Fund may invest 100% of its assets in fixed-income instruments that are or are deemed to be the equivalent in terms of quality to securities rated below investment grade by nationally recognized statistical rating agencies and accordingly involve great risk. Such securities are regarded as predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal in accordance with the terms of the obligations and involve major risk to adverse conditions. These securities offer higher returns than bonds with higher ratings as compensation for holding an obligation of an issuer perceived to be less creditworthy. The market prices of such securities are also subject to abrupt and erratic market movements and above-average price volatility, and the spread between the bid and ask prices of such securities may be greater than those prevailing in other securities markets. Changes in economic conditions or developments regarding issuers of non-investment grade debt securities are more likely to cause price volatility and weaken the capacity of such issuers to make principal and interest payments than is the case for higher grade debt securities. In addition, the market for lower grade debt securities may be thinner and less active than for higher grade debt securities.
CrossingBridge Ultra-Short Duration Fund | Convertible Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Convertible Securities Risk. A convertible security is a fixed-income security (a debt instrument or a preferred stock) which may be converted at a stated price within a specified period of time into a certain quantity of the common stock of the same or a different issuer. The market value of a convertible security performs like that of a regular debt security, that is, if market interest rates rise, the value of the convertible security falls.
CrossingBridge Ultra-Short Duration Fund | Corporate Events Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Corporate Events Risk. Corporate events risk is the risk that a corporate transaction or opportunity will not occur, or a natural disaster or regulatory change will cause an abrupt downgrade in a corporate bond which may lower the Fund’s performance.
CrossingBridge Ultra-Short Duration Fund | Credit-Related Instruments Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Credit-Related Instruments Risk. Interest rates may go up resulting in a decrease in the value of the securities held by the Fund. Interest rates have been rising from historically low levels, so the Fund faces a heightened risk that interest rates may continue to rise. A credit rating assigned to a particular debt security is essentially the opinion of an NRSRO as to the credit quality of an issuer and may prove to be inaccurate. There is also the risk that a bond issuer may “call,” or repay, its high yielding bonds before their maturity dates. Debt securities subject to prepayment can offer less potential for gains during a declining interest rate environment and similar or greater potential for loss in a rising interest rate environment. Limited trading opportunities for certain fixed income securities may make it more difficult to sell or buy a security at a favorable price or time, particularly during periods of market turmoil, and may also make these securities difficult to value.
CrossingBridge Ultra-Short Duration Fund | Credit Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock
Credit Risk. Debt portfolios are subject to credit risk. Credit risk refers to the likelihood that an issuer will default in the payment of principal and/or interest on an instrument. Financial strength and solvency of an issuer are the primary factors influencing credit risk. In addition, lack or inadequacy of collateral or credit enhancement for a debt instrument may affect its credit risk. Credit risk may change over the life of
an instrument, and debt obligations which are rated by rating agencies are often reviewed and may be subject to downgrade.
CrossingBridge Ultra-Short Duration Fund | Cybersecurity Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Cybersecurity Risk. With the increased use of technologies such as the Internet to conduct business, the Fund is susceptible to operational, information security, and related risks. Cyber incidents affecting the Fund or its service providers have the ability to cause disruptions and impact business operations, potentially resulting in financial losses, interference with the Fund’s ability to calculate its NAV, impediments to trading, the inability of shareholders to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs.
CrossingBridge Ultra-Short Duration Fund | Distressed Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Distressed Securities Risk. The Fund may invest in securities of companies that are experiencing significant financial or business difficulties, including companies involved in bankruptcy or other reorganization and liquidation proceedings. Although such investments may result in significant returns to the Fund, they involve a substantial degree of risk. Any one or all of the issuers of the securities in which the Fund may invest may be unsuccessful or not show any return for a considerable period of time. The level of analytical sophistication, both financial and legal, necessary for successful investment in companies experiencing significant business and financial difficulties is unusually high. There is no assurance that the Adviser will correctly evaluate the value of the assets collateralizing the Fund’s loans or the prospects for a successful reorganization or similar action. In any reorganization or liquidation proceeding relating to a company in which the Fund invests, the Fund may lose its entire investment or may be required to accept cash or securities with a value less than the Fund’s original investment. Under such circumstances, the returns generated from the Fund’s investments in distressed securities may not adequately compensate for the risks assumed. In addition, there is no minimum credit standard that is a prerequisite to the Fund’s investment in any instrument, and a significant portion of the obligations and preferred stock in which the Fund invests may be less than investment grade.
CrossingBridge Ultra-Short Duration Fund | Equity Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Equity Securities Risk. The Fund may invest in income producing equity securities. Although investments in income producing equity securities are considered safer than equity securities in general, and equities historically have been a leading choice for long-term investors, the values of stocks rise and fall depending on many factors. The stock or other security of a company may not perform as well as expected, and may decrease in value, because of factors related to the company (such as poorer than expected earnings or certain management decisions) or to the industry in which the company is engaged (such as a reduction in the demand for products or services in a particular industry). Market and economic factors may adversely affect securities markets generally, which could in turn adversely affect the value of the Fund’s investments, regardless of the performance or expected performance of companies in which the Fund invests.
CrossingBridge Ultra-Short Duration Fund | Fixed Income Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Fixed Income Securities Risk. The Fund invests a significant portion of its assets in fixed income securities. Fixed income securities are subject to credit risk and market risk, including interest rate risk. Credit risk is the risk of the issuer’s inability to meet its principal and interest payment obligations. Market risk is the risk of price volatility due to such factors as interest rate sensitivity, market perception of the creditworthiness of the issuer and general market liquidity. There is no limitation on the maturities of fixed income securities in which the Fund invests. Securities having longer maturities generally involve greater risk of fluctuations in value resulting from changes in interest rates.
CrossingBridge Ultra-Short Duration Fund | Fixed Income Securities Market Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock
Fixed Income Securities Market Risk. Difficult conditions in the broader financial markets have in the past resulted in a temporary but significant contraction in liquidity for fixed income securities. Liquidity relates to the ability of the Fund to sell its investments in a timely manner at a price approximately equal to its value on the Fund’s books. To the extent that the market for fixed income securities suffers such a contraction, securities that were considered liquid at the time of investment could become temporarily illiquid, and the Adviser may experience delays or difficulty in selling assets at the prices at which the Fund carries such assets, which may result in a loss to the Fund. There is no way to predict reliably when such market conditions could re-occur or how long such conditions could persist.
In the event of a severe market contraction precipitated by general market turmoil, economic conditions, changes in prevailing interest rates or otherwise, coupled with extraordinary levels of Fund shareholder
redemption requests, the Fund may have to consider selling its holdings at a loss including at prices below the current value on the Fund’s books, borrowing money to satisfy redemption requests in accordance with the Fund’s borrowing policy or postponing payment of redemption requests for up to seven days or longer, as permitted by applicable law, or other extraordinary measures. In addition, if the Fund needed to sell large blocks of investments to meet shareholder redemption requests or to raise cash, those sales could further reduce prices, particularly for lower-rated and unrated securities.
In response to rising inflation, the Federal Reserve began raising short-term interest rates in 2022 with the potential for further rate increases. Uncertainty regarding the ability of the Federal Reserve to successfully control inflation, the potential for incremental rate increases, and the full impact of prior rate increases may negatively impact fixed income security prices and increase market volatility. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities.
CrossingBridge Ultra-Short Duration Fund | Floating Rate Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Floating Rate Risk. Securities with floating interest rates generally are less sensitive to interest rate changes but may decline in value if their interest rates do not rise as much, or as quickly, as interest rates in general. Conversely, floating rate instruments will not generally increase in value if interest rates decline. Changes in interest rates will also affect the amount of interest income the Fund earns on its floating rate investments.
CrossingBridge Ultra-Short Duration Fund | Foreign Investments Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Foreign Investments Risk. Investments in fixed income securities of U.S. and foreign issuers and instruments that are linked to fixed income securities (collectively, “Credit-Related Instruments”) involve certain risks not generally associated with investments in the securities of U.S. issuers, including changes in currency exchange rates, unstable political, social and economic conditions, a lack of adequate or accurate company information, differences in the way securities markets operate, less secure international banks or securities depositories than those in the U.S. and foreign controls on investment. In addition, individual international country economies may differ favorably or unfavorably from the U.S. economy in such respects as growth of gross domestic product, rates of inflation, capital reinvestment, resources, self-sufficiency and balance of payments position. Income earned on foreign investments may be subject to foreign withholding taxes.
CrossingBridge Ultra-Short Duration Fund | Forward Currency Contracts Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock
Forward Currency Contracts. The Fund may enter into forward currency contracts. A forward currency contract is an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days from the date of the contract agreed upon by the parties, at a price set at the time of the contract. For example, the Fund might purchase a particular currency or enter into a forward currency contract to preserve the U.S. dollar price of securities it intends to or has contracted to purchase. Alternatively, it might sell a particular currency on either a spot or forward basis to hedge against an anticipated decline in the dollar value of securities it intends to or has contracted to sell. Although this
strategy could minimize the risk of loss due to a decline in the value of the hedged currency, it could also limit any potential gain from an increase in the value of the currency.
CrossingBridge Ultra-Short Duration Fund | General Market Risk Member

The Fund invests in securities issued or guaranteed by the U.S. Government, its agencies and instrumentalities (including government-sponsored enterprises). Securities issued by agencies and instrumentalities may not be guaranteed or insured by the U.S. Government and may only be supported by the credit of the issuing entity.
CrossingBridge Ultra-Short Duration Fund | High Portfolio Turnover Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock High Portfolio Turnover Risk. The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Fund’s performance.
CrossingBridge Ultra-Short Duration Fund | Interest Rate Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Interest Rate Risk. The prices of securities in general and fixed-income securities in particular tend to be sensitive to interest rate fluctuations. Increases in interest rates can result in significant declines in the prices of fixed-income securities. Securities with floating interest rates generally are less sensitive to interest rate changes but may decline in value if their interest rates do not rise as much, or as quickly, as interest rates in general. The negative impact on fixed income securities generally from rate increases, regardless of the cause, could be swift and significant, which could result in losses by the Fund, even if anticipated by the Adviser. Starting in 2022, the Federal Reserve began to increase interest rates in an effort to combat inflation which has resulted in periods of volatility.
CrossingBridge Ultra-Short Duration Fund | Liquidity Risk Member

CrossingBridge Ultra-Short Duration Fund | Recent Market Events Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock
Recent Market Events Risk. U.S. and international markets have experienced and may continue to experience significant periods of volatility in recent years and months due to a number of economic, political and global macro factors including uncertainty regarding inflation and central banks’ interest rate increases, the possibility of a national or global recession, trade tensions, political events, the war between Russia and Ukraine, significant conflict between Israel and Hamas in the Middle East, and the impact of the coronavirus (COVID-19) global pandemic. The impact of COVID-19 may last for an extended period of time. As a result of continuing political tensions and armed conflicts, including the war between Ukraine and Russia, the U.S. and the European Union imposed sanctions on certain Russian individuals
and companies, including certain financial institutions, and have limited certain exports and imports to and from Russia. The war has contributed to recent market volatility and may continue to do so. Continuing market volatility as a result of recent market conditions or other events may have an adverse effect on the performance of the Fund.
CrossingBridge Ultra-Short Duration Fund | Redemption Risk Member

CrossingBridge Ultra-Short Duration Fund | Sovereign Debt Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Sovereign Debt Risk. The Fund may invest in securities issued or guaranteed by foreign governmental entities (known as sovereign debt securities). These investments are subject to the risk of payment delays or defaults, due, for example, to cash flow problems, insufficient foreign currency reserves, political considerations, large debt positions relative to the country’s economy, or failure to implement economic reforms. There is no legal or bankruptcy process for collecting sovereign debt.
CrossingBridge Ultra-Short Duration Fund | SPACs Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock SPACs Risk. The Fund invests in equity securities of SPACs, which raise assets to seek potential business combination opportunities. Unless and until a business combination is completed, a SPAC generally invests its assets in U.S. government securities, money market securities, and cash. Because SPACs have no operating history or ongoing business other than seeking a business combination, the value of their securities is particularly dependent on the ability of the entity’s management to identify and complete a profitable business combination. There is no guarantee that the SPACs in which the Fund invests will complete a business combination or that any business combination that is completed will be profitable. The market perception of a SPAC’s ability to complete a business combination could materially impact the market value of the SPAC’s securities. Public stockholders of SPACs may not be afforded a meaningful opportunity to vote on a proposed initial business combination because certain stockholders, including stockholders affiliated with the management of the SPAC, may have sufficient voting power, and a financial incentive, to approve such a transaction without support from public stockholders. As a result, a SPAC may complete a business combination even though a majority of its public stockholders do not support such a combination. Some SPACs may pursue a business combination only within certain industries or regions, which may increase the volatility of their prices.
CrossingBridge Ultra-Short Duration Fund | Trade Versus Settlement Risk Member

CrossingBridge Ultra-Short Duration Fund | Zero Coupon Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock
Zero Coupon Securities Risk. While interest payments are not made on such securities, holders of such securities are deemed to have received income annually, notwithstanding that cash may not be received currently. Some of these securities may be subject to substantially greater price fluctuations during periods of changing market interest rates than are comparable securities that pay interest currently.
Longer term zero coupon bonds are more exposed to interest rate risk than shorter term zero coupon bonds.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Fund seeks to achieve its investment objective by investing primarily in fixed income securities while actively managing interest rate and default risks. Under normal circumstances, the Fund invests at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in fixed income securities that meet the Adviser’s responsible investing criteria.
Investment decisions for the Fund are made by the Adviser based on a bottom-up analysis of an issuer’s business model, quantitative and qualitative factors, as well as the Adviser’s “responsible investing criteria” (i.e., specific exclusionary and inclusionary criteria based on environmental, social and governance (“ESG”) standards). The Adviser utilizes a proprietary matrix to measure an issuer’s ESG engagement. The Adviser’s proprietary matrix sets a minimum threshold level that must be achieved for an issuer’s securities or other instruments to satisfy the Fund’s responsible investing criteria. The Adviser sources information relating to its responsible investing criteria from publicly-available resources such as financial filings, presentations, news articles, and management discussions. The Adviser monitors an issuer’s conformity to its responsible investing criteria and each holding will be formally reviewed by the Adviser at least annually.

The Adviser believes that ESG industry standards will evolve over time, and such standards will continue to enhance the Adviser’s ability to identify and measure behaviors. The Adviser believes that certain products and business practices of an issuer may be detrimental and incompatible with mainstream views of responsible investing. Therefore, certain exclusionary criteria are applied by the Adviser as a first step in determining an individual investment’s suitability for the Fund. Issuers whose business is primarily engaged in one of the following activities will be excluded from the Fund:

•Weapons;
•Tobacco;
•Alcohol and Marijuana (for Recreational Purposes);
•Gambling;
•Pornography/Adult Entertainment;
•Certain Fossil Fuels (including Coal Mining and Fracking Exploration);
•Nuclear Fission (typically Power Plants);
•International Norms Violations; and
•Corporations or Sovereign Entities not adhering to the United Nations Global Compact Principles and the Organization for Economic Co-operation and Development (OECD) Guidelines for Multi-National Enterprises.
The Adviser considers any issuer whose business generates 10% or more of its revenues from one of the activities noted above to be “primarily engaged” in such activities and subject to exclusion. The Adviser may expand the list of exclusionary activities from time to time. The Adviser applies its exclusionary criteria to any investment considered for inclusion in the Fund’s portfolio.

The Adviser believes that applying an exclusionary screen to issuers that are non-conforming to its ESG standards is an important first step, but believes it is also important to integrate those issuers that have a positive ESG impact or ESG mindfulness that meet the Adviser’s inclusionary criteria described in the objectives below. The Adviser believes that responsible issuers can reward shareholders while being mindful of their ESG impact. As a responsible investor, the Adviser seeks to invest with issuers providing positive leadership in the pursuit of the following objectives:

Environmental Objectives:

•Reduce the negative operational impact and practices on the environment;
•Reduce the use of scarce resources;
•Reduce carbon emissions; and
•Pursue resource efficiency, sustainability, and innovation.

Social Objectives:

•Treat all constituencies in a proper and ethical manner;
•Address all constituencies in a fair and equitable manner;
•Promote health and well-being for all constituencies;
•Protect sensitive data for all constituencies;
•Market products in a sincere and factual approach;
•Provide employees with development and opportunity in an appropriate workplace; and
•Recognize barriers of underrepresented groups by supporting diversity and inclusion.

Governance Objectives:

•Independent members of an issuers Board that provide checks and balances;
•Diversification of backgrounds, skills, and philosophy among an issuers Board or executive officers;
•Promote transparency and communication;
•Exercise and supports law abidingness externally and from within;
•Develop programs to measure and improve environmental impact and social practices;
•Respect lenders rights and value similarly to shareholders; and
•Advocate ethical standards in operations and dealings with customers, employees, regulators, business partners and the greater community.

At least 80% of the Fund’s assets will be comprised of investments of issuers satisfying the Adviser’s minimum threshold for the inclusionary criteria. The Adviser deems governmental securities of G7 countries (Canada, France, Germany, Italy, Japan, the United Kingdom and the United States) to be of the highest ESG quality. Governmental securities of non-G7 countries will be evaluated by the Adviser on a case-by-case basis for inclusion in the Fund’s investment portfolio.

The Fund defines fixed income securities to include: bills, notes, bonds, debentures, convertible bonds, loan participations, mortgage- and asset-backed securities, Rule 144A fixed income securities, zero coupon securities, syndicated loan assignments, sovereign debt and other evidence of indebtedness issued by U.S. or foreign corporations, governments, government agencies or government instrumentalities,
including floating-rate securities, commercial paper, preferred stock and fixed income-like equities. Convertible bonds, preferred stocks, and fixed income-like equities (e.g. special purpose acquisition companies (“SPACs”)) provide interest income and/or the potential for capital appreciation while having an effective maturity. Floating-rate securities provide interest income that can increase or decrease with interest rates. The Fund invests in individual fixed income securities without restriction as to issuer credit quality, capitalization or security maturity. The Fund may invest up to 100% of its assets in lower-quality fixed income securities — commonly known as “high yield” or “junk” bonds. Junk bonds are generally rated lower than Baa3 by Moody’s Investors Service (“Moody’s”) or lower than BBB- by Standard and Poor’s Rating Group (“S&P”). The Fund may invest in junk bonds that are in default, subject to bankruptcy or reorganization. High yield bonds have a higher expected rate of default than higher quality bonds.
The Adviser seeks to manage duration, currency, and default risks. Although the Adviser will take macro factors into consideration, the portfolio duration is primarily driven by bottom-up investment opportunities. Under normal market conditions, the Adviser will generally pursue a portfolio duration of 2 to 4. Duration is a measure of sensitivity of a security’s price to changes in interest rates. For example, a security with a duration of 2 would be expected to decrease in price 2% for every 1% rise in interest rates (the inverse is true as well).
The Adviser manages default risk by selecting securities of issuers that it believes will pay interest and principal regardless of their credit rating, based upon the Adviser’s credit analysis of each issuer. The Adviser may also select securities that are in default, subject to bankruptcy or reorganization where the Adviser believes the risks to be consistent with capital preservation, based on the Adviser’s analysis of an issuer’s liquidation value or post-bankruptcy or post-reorganization value.
The Adviser manages foreign currency risk by investing primarily in securities denominated in U.S. dollars, such as Yankee bonds. If the Fund were to invest in foreign currency denominated securities, the Fund restricts such activity to less than 35% of the Fund’s total assets. When deemed appropriate, the Adviser may hedge the foreign currency exposure typically, and primarily, with forward currency contracts. A forward currency contract is an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days from the date of the contract agreed upon by the parties.
The Fund is “non-diversified” for purposes of the Investment Company Act of 1940, as amended (the “1940 Act”), which means that the Fund may invest in fewer securities at any one time than a diversified fund. However, the adviser manages the impact of the risk of each investment by a considered analysis of appropriate sizing and portfolio diversification.
The Fund may engage in active trading of its portfolio, resulting in a high turnover rate.
There is no assurance that the Fund will achieve its investment objective.
Strategy Portfolio Concentration [Text] rr_StrategyPortfolioConcentration Under normal market conditions, the Adviser will generally pursue a portfolio duration of 2 to 4.

In making investments in such loans, which are made by banks or other financial intermediaries to borrowers, the Fund will depend primarily upon the creditworthiness of the borrower for payment of principal and interest. As a result, sale proceeds related to the sale of loans may not be available to make additional investments or to meet the Fund’s redemption obligations until potentially a substantial period after the sale of the loans. The Fund, therefore, may be forced to sell other assets at a loss to pay redemption proceeds. A significant portion of bank loans may be “covenant lite” loans that may contain fewer or less restrictive constraints on the borrower and fewer or no financial maintenance covenants and restrictions. A covenant lite loan typically contains fewer clauses which allow an investor to proactively enforce financial covenants. Covenant lite loans also generally provide fewer investor protections if certain criteria are breached. The Fund may experience losses or delays in enforcing its rights on its holdings of covenant lite loans. The secondary market for bank loans is a private, unregulated inter-dealer or inter-bank resale market. Purchases and sales of loans are generally subject to contractual restrictions that must be satisfied before a loan can be bought or sold. These restrictions may impede the Fund’s ability to buy or sell loans and may negatively impact the transaction price. It may take longer than seven days for transactions in loans to settle. The Fund may hold cash, sell investments or temporarily borrow from banks to meet short-term liquidity needs due to the extended loan settlement process, such as to satisfy redemption requests from Fund shareholders. U.S. federal securities laws afford certain protections against fraud and misrepresentation in connection with the offering or sale of a security, as well as against manipulation of trading markets for securities. The typical practice of a lender in relying exclusively or primarily on reports from the borrower may involve the risk of fraud, misrepresentation, or market manipulation by the borrower. It is unclear whether U.S. federal securities law protections are available to an investment in a loan. In certain circumstances, loans may not be deemed to be securities, and in the event of fraud or misrepresentation by a borrower, lenders may not have the protection of the anti-fraud provisions of the federal securities laws. However, contractual provisions in the loan documents may offer some protections, and lenders may also avail themselves of common-law fraud protections under applicable state law.
CrossingBridge Responsible Credit Fund | Below Investment Grade Securities Risk (Commonly Referred To As “Junk” Bonds) Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Below Investment Grade Securities Risks (commonly referred to as “junk” bonds). The Fund may invest 100% of its assets in fixed-income instruments that are or are deemed to be the equivalent in terms of quality to securities rated below investment grade by nationally recognized statistical rating agencies and accordingly involve great risk. Such securities are regarded as predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal in accordance with the terms of the obligations and involve major risk to adverse conditions. These securities offer higher returns than bonds with higher ratings as compensation for holding an obligation of an issuer perceived to be less creditworthy. The market prices of such securities are also subject to abrupt and erratic market movements and above-average price volatility, and the spread between the bid and ask prices of such securities may be greater than those prevailing in other securities markets. Changes in economic conditions or developments regarding issuers of non-investment grade debt securities are more likely to cause price volatility and weaken the capacity of such issuers to make principal and interest payments than is the case for higher grade debt securities. In addition, the market for lower grade debt securities may be thinner and less active than for higher grade debt securities.
CrossingBridge Responsible Credit Fund | Convertible Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Convertible Securities Risk. A convertible security is a fixed-income security (a debt instrument or a preferred stock) which may be converted at a stated price within a specified period of time into a certain quantity of the common stock of the same or a different issuer. The market value of a convertible security performs like that of a regular debt security, that is, if market interest rates rise, the value of the convertible security falls.
CrossingBridge Responsible Credit Fund | Corporate Events Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Corporate Events Risk. Corporate events risk is the risk that a corporate transaction or opportunity will not occur, or a natural disaster or regulatory change will cause an abrupt downgrade in a corporate bond which may lower the Fund’s performance.
CrossingBridge Responsible Credit Fund | Credit-Related Instruments Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Credit-Related Instruments Risk. Interest rates may go up resulting in a decrease in the value of the securities held by the Fund. Interest rates have been rising from historically low levels, so the Fund faces a heightened risk that interest rates may continue to rise. A credit rating assigned to a particular debt security is essentially the opinion of an NRSRO as to the credit quality of an issuer and may prove to be inaccurate. There is also the risk that a bond issuer may “call,” or repay, its high yielding bonds before their maturity dates. Debt securities subject to prepayment can offer less potential for gains during a declining interest rate environment and similar or greater potential for loss in a rising interest rate environment. Limited trading opportunities for certain fixed income securities may make it more difficult to sell or buy a security at a favorable price or time, particularly during periods of market turmoil, and may also make these securities difficult to value.
CrossingBridge Responsible Credit Fund | Credit Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Credit Risk. Debt portfolios are subject to credit risk. Credit risk refers to the likelihood that an issuer will default in the payment of principal and/or interest on an instrument. Financial strength and solvency of an issuer are the primary factors influencing credit risk. In addition, lack or inadequacy of collateral or credit enhancement for a debt instrument may affect its credit risk. Credit risk may change over the life of an instrument, and debt obligations which are rated by rating agencies are often reviewed and may be subject to downgrade.
CrossingBridge Responsible Credit Fund | Cybersecurity Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Cybersecurity Risk. With the increased use of technologies such as the Internet to conduct business, the Fund is susceptible to operational, information security, and related risks. Cyber incidents affecting the Fund or its service providers have the ability to cause disruptions and impact business operations, potentially resulting in financial losses, interference with the Fund’s ability to calculate its NAV, impediments to trading, the inability of shareholders to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs.
CrossingBridge Responsible Credit Fund | Distressed Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock
Distressed Securities Risk. The Fund may invest in securities of companies that are experiencing significant financial or business difficulties, including companies involved in bankruptcy or other reorganization and liquidation proceedings. Although such investments may result in significant returns to the Fund, they involve a substantial degree of risk. Any one or all of the issuers of the securities in which the Fund may invest may be unsuccessful or not show any return for a considerable period of time. The level of analytical sophistication, both financial and legal, necessary for successful investment in companies experiencing significant business and financial difficulties is unusually high. There is no assurance that the Adviser will correctly evaluate the value of the assets collateralizing the Fund’s loans or the prospects for a successful reorganization or similar action. In any reorganization or liquidation proceeding relating to a company in which the Fund invests, the Fund may lose its entire investment or may be required to accept cash or securities with a value less than the Fund’s original investment. Under
such circumstances, the returns generated from the Fund’s investments in distressed securities may not adequately compensate for the risks assumed. In addition, there is no minimum credit standard that is a prerequisite to the Fund’s investment in any instrument, and a significant portion of the obligations and preferred stock in which the Fund invests may be less than investment grade.
CrossingBridge Responsible Credit Fund | Equity Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Equity Securities Risk. The Fund may invest in income producing equity securities. Although investments in income producing equity securities are considered safer than equity securities in general, and equities historically have been a leading choice for long-term investors, the values of stocks rise and fall depending on many factors. The stock or other security of a company may not perform as well as expected, and may decrease in value, because of factors related to the company (such as poorer than expected earnings or certain management decisions) or to the industry in which the company is engaged (such as a reduction in the demand for products or services in a particular industry). Market and economic factors may adversely affect securities markets generally, which could in turn adversely affect the value of the Fund’s investments, regardless of the performance or expected performance of companies in which the Fund invests.
CrossingBridge Responsible Credit Fund | ESG Investment Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock ESG Investment Risk. The Fund’s focus on sustainability considerations (ESG criteria) may limit the number of investment opportunities available to the Fund, and as a result, at times, the Fund may underperform funds that are not subject to similar investment considerations.
CrossingBridge Responsible Credit Fund | Fixed Income Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock
Fixed Income Securities Risk. The Fund invests a significant portion of its assets in fixed income securities. Fixed income securities are subject to credit risk and market risk, including interest rate risk. Credit risk is the risk of the issuer’s inability to meet its principal and interest payment obligations. Market risk is the risk of price volatility due to such factors as interest rate sensitivity, market perception
of the creditworthiness of the issuer and general market liquidity. There is no limitation on the maturities of fixed income securities in which the Fund invests. Securities having longer maturities generally involve greater risk of fluctuations in value resulting from changes in interest rates.
CrossingBridge Responsible Credit Fund | Fixed Income Securities Market Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock
Fixed Income Securities Market Risk. Difficult conditions in the broader financial markets have in the past resulted in a temporary but significant contraction in liquidity for fixed income securities. Liquidity relates to the ability of the Fund to sell its investments in a timely manner at a price approximately equal to its value on the Fund’s books. To the extent that the market for fixed income securities suffers such a contraction, securities that were considered liquid at the time of investment could become temporarily illiquid, and the Adviser may experience delays or difficulty in selling assets at the prices at which the Fund carries such assets, which may result in a loss to the Fund. There is no way to predict reliably when such market conditions could re-occur or how long such conditions could persist.
In the event of a severe market contraction precipitated by general market turmoil, economic conditions, changes in prevailing interest rates or otherwise, coupled with extraordinary levels of Fund shareholder redemption requests, the Fund may have to consider selling its holdings at a loss including at prices below the current value on the Fund’s books, borrowing money to satisfy redemption requests in accordance with the Fund’s borrowing policy or postponing payment of redemption requests for up to seven days or longer, as permitted by applicable law, or other extraordinary measures. In addition, if the Fund needed to sell large blocks of investments to meet shareholder redemption requests or to raise cash, those sales could further reduce prices, particularly for lower-rated and unrated securities.
In response to rising inflation, the Federal Reserve began raising short-term interest rates in 2022 with the potential for further rate increases. Uncertainty regarding the ability of the Federal Reserve to successfully control inflation, the potential for incremental rate increases, and the full impact of prior rate increases may negatively impact fixed income security prices and increase market volatility. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities.
CrossingBridge Responsible Credit Fund | Floating Rate Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Floating Rate Risk. Securities with floating interest rates generally are less sensitive to interest rate changes but may decline in value if their interest rates do not rise as much, or as quickly, as interest rates in general. Conversely, floating rate instruments will not generally increase in value if interest rates decline. Changes in interest rates will also affect the amount of interest income the Fund earns on its floating rate investments.
CrossingBridge Responsible Credit Fund | Foreign Investments Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Foreign Investments Risk. Investments in fixed income securities of U.S. and foreign issuers and instruments that are linked to fixed income securities (collectively, “Credit-Related Instruments”) involve certain risks not generally associated with investments in the securities of U.S. issuers, including changes in currency exchange rates, unstable political, social and economic conditions, a lack of adequate or accurate company information, differences in the way securities markets operate, less secure international banks or securities depositories than those in the U.S. and foreign controls on investment. In addition, individual international country economies may differ favorably or unfavorably from the U.S. economy in such respects as growth of gross domestic product, rates of inflation, capital reinvestment, resources, self-sufficiency and balance of payments position. Income earned on foreign investments may be subject to foreign withholding taxes.
CrossingBridge Responsible Credit Fund | Forward Currency Contracts Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Forward Currency Contracts. The Fund may enter into forward currency contracts. A forward currency contract is an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days from the date of the contract agreed upon by the parties, at a price set at the time of the contract. For example, the Fund might purchase a particular currency or enter into a forward currency contract to preserve the U.S. dollar price of securities it intends to or has contracted to purchase. Alternatively, it might sell a particular currency on either a spot or forward basis to hedge against an anticipated decline in the dollar value of securities it intends to or has contracted to sell. Although this strategy could minimize the risk of loss due to a decline in the value of the hedged currency, it could also limit any potential gain from an increase in the value of the currency.
CrossingBridge Responsible Credit Fund | General Market Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems

Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Government Securities Risk. The Fund invests in securities issued or guaranteed by the U.S. Government, its agencies and instrumentalities (including government-sponsored enterprises). Securities issued by agencies and instrumentalities may not be guaranteed or insured by the U.S. Government and may only be supported by the credit of the issuing entity.
CrossingBridge Responsible Credit Fund | High Portfolio Turnover Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock High Portfolio Turnover Risk. The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Fund’s performance.
CrossingBridge Responsible Credit Fund | Interest Rate Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock
Interest Rate Risk. The prices of securities in general and fixed-income securities in particular tend to be sensitive to interest rate fluctuations. Increases in interest rates can result in significant declines in the prices of fixed-income securities. Securities with floating interest rates generally are less sensitive to interest rate changes but may decline in value if their interest rates do not rise as much, or as quickly, as
interest rates in general. The negative impact on fixed income securities generally from rate increases, regardless of the cause, could be swift and significant, which could result in losses by the Fund, even if anticipated by the Adviser. Starting in 2022, the Federal Reserve began to increase interest rates in an effort to combat inflation which has resulted in periods of volatility.
CrossingBridge Responsible Credit Fund | Liquidity Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems

CrossingBridge Responsible Credit Fund | Preferred Stock Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Preferred Stock Risk. Preferred stocks may be more volatile than fixed income securities and are more correlated with the issuer’s underlying common stock than fixed income securities. Additionally, the dividend on a preferred stock may be changed or omitted by the issuer, and participation in the growth of an issuer may be limited.
CrossingBridge Responsible Credit Fund | Prepayment Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Prepayment Risk. The risk that the issuer of a debt security repays all or a portion of the principal prior to the security’s maturity therefore resulting in lower yields to shareholders of the Fund. The Fund may be unable to re-invest the proceeds in an investment with as great a yield.
CrossingBridge Responsible Credit Fund | Risk Nondiversified Status [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Non-Diversification Risk. The Fund is classified as a “non-diversified” investment company under the Investment Company Act of 1940, as amended (the “1940 Act”). Therefore, the Fund may invest a relatively high percentage of its assets in a smaller number of issuers or may invest a larger proportion of its assets in the obligations of a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s net asset value (“NAV”) and may make the Fund more volatile than more diversified funds.
CrossingBridge Responsible Credit Fund | Recent Market Events Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Recent Market Events Risk. U.S. and international markets have experienced and may continue to experience significant periods of volatility in recent years and months due to a number of economic, political and global macro factors including uncertainty regarding inflation and central banks’ interest rate increases, the possibility of a national or global recession, trade tensions, political events, the war between Russia and Ukraine, significant conflict between Israel and Hamas in the Middle East, and the impact of the coronavirus (COVID-19) global pandemic. The impact of COVID-19 may last for an extended period of time. As a result of continuing political tensions and armed conflicts, including the war between Ukraine and Russia, the U.S. and the European Union imposed sanctions on certain Russian individuals and companies, including certain financial institutions, and have limited certain exports and imports to and from Russia. The war has contributed to recent market volatility and may continue to do so. Continuing market volatility as a result of recent market conditions or other events may have an adverse effect on the performance of the Fund.
CrossingBridge Responsible Credit Fund | Redemption Risk Member

Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Rule 144A Securities Risk. The market for Rule 144A securities typically is less active than the market for publicly-traded securities.

CrossingBridge Responsible Credit Fund | Sovereign Debt Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Sovereign Debt Risk. The Fund may invest in securities issued or guaranteed by foreign governmental entities (known as sovereign debt securities). These investments are subject to the risk of payment delays or defaults, due, for example, to cash flow problems, insufficient foreign currency reserves, political considerations, large debt positions relative to the country’s economy, or failure to implement economic reforms. There is no legal or bankruptcy process for collecting sovereign debt.
CrossingBridge Responsible Credit Fund | SPACs Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock SPACs Risk. The Fund invests in equity securities of SPACs, which raise assets to seek potential business combination opportunities. Unless and until a business combination is completed, a SPAC generally invests its assets in U.S. government securities, money market securities, and cash. Because SPACs have no operating history or ongoing business other than seeking a business combination, the value of their securities is particularly dependent on the ability of the entity’s management to identify and complete a profitable business combination. There is no guarantee that the SPACs in which the Fund invests will complete a business combination or that any business combination that is completed will be profitable. The market perception of a SPAC’s ability to complete a business combination could materially impact the market value of the SPAC’s securities. Public stockholders of SPACs may not be afforded a meaningful opportunity to vote on a proposed initial business combination because certain stockholders, including stockholders affiliated with the management of the SPAC, may have sufficient voting power, and a financial incentive, to approve such a transaction without support from public stockholders. As a result, a SPAC may complete a business combination even though a majority of its public stockholders do not support such a combination. Some SPACs may pursue a business combination only within certain industries or regions, which may increase the volatility of their prices.
CrossingBridge Responsible Credit Fund | Trade Versus Settlement Risk Member

While interest payments are not made on such securities, holders of such securities are deemed to have received income annually, notwithstanding that cash may not be received currently. Some of these securities may be subject to substantially greater price fluctuations during periods of changing market interest rates than are comparable securities that pay interest currently. Longer term zero coupon bonds are more exposed to interest rate risk than shorter term zero coupon bonds.

The Fund seeks to achieve its investment objective by investing in both investment grade and non-investment grade debt, preferred stock, convertible bonds (i.e., debt securities that provide the Fund with a right or an obligation to exchange the debt security for a predetermined number of shares in the issuing
company), bank loans, high yield bonds, mortgage- and asset-backed securities, special purpose acquisition companies (“SPACs”) and income producing equities (collectively, “Securities”) that CrossingBridge Advisors, LLC (the “Adviser”), the Fund’s investment adviser, deems appropriate for the Fund’s investment objective. The Fund will invest at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in fixed income securities and income producing equities. The Fund may invest up to 100% of its assets in fixed income securities. The Fund will invest in fixed income securities of various credit qualities (i.e., investment grade and below investment grade (i.e., junk bonds)) and maturities (i.e., long-term, intermediate and short-term). The Fund may invest up to 100% of its assets in below investment grade fixed income securities. The Fund will invest in individual fixed income securities without restriction as to duration. The Fund’s investment in below investment grade fixed income securities may include distressed securities, which are fixed income securities issued by companies experiencing significant financial or business difficulties such as bankruptcy, reorganization or liquidation proceedings. The Fund will invest primarily in U.S. dollar-denominated securities but may invest up to 35% of its assets in foreign fixed income securities including sovereign debt and foreign currency-denominated securities. The Fund may hedge the foreign currency exposure by investing in forward currency contracts. A forward currency contract is an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days from the date of the contract agreed upon by the parties. The Fund may also invest up to 35% of its assets in income producing equities that either have a substantial dividend yield or where the Adviser believes the issuing company will distribute significant assets over a certain period of time. The Fund’s investments will be diversified across individual issuers and industries. The Fund, however, will invest without restriction as to issuer credit quality, or security maturity.

Although the Adviser will take macro factors (i.e., the effect of interest rates on the Fund’s investments) into consideration, the Fund’s portfolio construction is primarily driven by bottom-up investment analysis. This means that the Adviser looks at Securities on an individual basis to determine if a Security is an attractive investment opportunity and if it is consistent with the Fund’s investment objective. The Fund’s buy and sell decisions are driven by the Adviser’s investment process. The Fund may hold Securities until maturity but will sell a Security when the Adviser determines a Security is no longer an attractive investment opportunity consistent with the Fund’s investment objective, when a more attractive investment opportunity becomes available or to satisfy redemption requests. In addition, a Security may be purchased at a premium or discount and/or sold prior to maturity where the Adviser believes it is advantageous to do so. The Fund may invest up to 15% of the value of its total assets to effect short sales of securities, including up to 10% in short sales of exchange-traded funds (“ETFs”) to hedge the portfolio if the Adviser believes it is consistent with achieving the Fund’s investment objective. Other than for temporary purposes, the Fund will not borrow in order to gain leverage.

The Fund may engage in active trading of its portfolio, resulting in a high turnover rate.

There is no assurance that the Fund will achieve its investment objectives.
Strategy Portfolio Concentration [Text] rr_StrategyPortfolioConcentration The Fund seeks to achieve its investment objective by investing in both investment grade and non-investment grade debt, preferred stock, convertible bonds (i.e., debt securities that provide the Fund with a right or an obligation to exchange the debt security for a predetermined number of shares in the issuing company), bank loans, high yield bonds, mortgage- and asset-backed securities, special purpose acquisition companies (“SPACs”) and income producing equities (collectively, “Securities”) that CrossingBridge Advisors, LLC (the “Adviser”), the Fund’s investment adviser, deems appropriate for the Fund’s investment objective. The Fund will invest at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in fixed income securities and income producing equities. The Fund may invest up to 100% of its assets in fixed income securities. The Fund will invest in fixed income securities of various credit qualities (i.e., investment grade and below investment grade (i.e., junk bonds)) and maturities (i.e., long-term, intermediate and short-term). The Fund may invest up to 100% of its assets in below investment grade fixed income securities. The Fund will invest in individual fixed income securities without restriction as to duration. The Fund’s investment in below investment grade fixed income securities may include distressed securities, which are fixed income securities issued by companies experiencing significant financial or business difficulties such as bankruptcy, reorganization or liquidation proceedings. The Fund will invest primarily in U.S. dollar-denominated securities but may invest up to 35% of its assets in foreign fixed income securities including sovereign debt and foreign currency-denominated securities. The Fund may hedge the foreign currency exposure by investing in forward currency contracts. A forward currency contract is an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days from the date of the contract agreed upon by the parties. The Fund may also invest up to 35% of its assets in income producing equities that either have a substantial dividend yield or where the Adviser believes the issuing company will distribute significant assets over a certain period of time. The Fund’s investments will be diversified across individual issuers and industries. The Fund, however, will invest without restriction as to issuer credit quality, or security maturity.

The Average Annual Total Returns table also demonstrates these risks by showing how average annual returns for the Fund’s Institutional Class and Retail Class shares for the one year, five year, and ten year periods compare with those of a broad measure of market performance as well as the performance of two categories of mutual funds comprised
of funds that are managed with similar investment strategies to the Fund. Performance data for the classes varies based on differences in their fee and expense structures. Performance for Retail Class shares would be lower as expenses for Retail Class shares are higher.

Effective on May 12, 2023, the RiverPark Strategic Income Fund, a series of RiverPark Funds Trust (the “Predecessor Fund”) reorganized into the Fund, a newly-created series of the Trust (the “Reorganization”). For periods prior to the Reorganization the performance figures for Institutional Class and Retail Class shares reflect the historical performance of the Institutional Class and Retail Class shares, respectively, of the Predecessor Fund. Cohanzick Management, LLC, an affiliated entity of the Adviser, served as the investment sub-adviser of the Predecessor Fund, and David K. Sherman, the Fund’s sole portfolio manager, served as the sole portfolio manager of the Predecessor Fund since the Predecessor Fund’s inception. The Fund has adopted the performance and financial history of the Predecessor Fund.

Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Asset-Backed and Mortgage-Backed Securities Risk. Asset-backed and mortgage-backed securities are subject to risk of prepayment. These types of securities may also decline in value because of mortgage foreclosures or defaults on the underlying obligations. Asset-backed and mortgage-backed securities are also subject to extension risk, the risk that rising interest rates could cause prepayments to decrease, extending the life of asset-backed and mortgage-backed securities with lower payment rates.
RiverPark Strategic Income Fund | Bank Loans Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Bank Loans Risk. The Fund’s investments in secured and unsecured assignments and/or participations in bank loans may create substantial risk. In making investments in such loans, which are made by banks or other financial intermediaries to borrowers, the Fund will depend primarily upon the creditworthiness of the borrower for payment of principal and interest. As a result, sale proceeds related to the sale of loans may not be available to make additional investments or to meet the Fund’s redemption obligations until potentially a substantial period after the sale of the loans. The Fund, therefore, may be forced to sell other assets at a loss to pay redemption proceeds. A significant portion of bank loans may be “covenant lite” loans that may contain fewer or less restrictive constraints on the borrower and fewer or no financial maintenance covenants and restrictions. A covenant lite loan typically contains fewer clauses which allow an investor to proactively enforce financial covenants. Covenant lite loans also generally provide fewer investor protections if certain criteria are breached. The Fund may experience losses or delays in enforcing its rights on its holdings of covenant lite loans. The secondary market for bank loans is a private, unregulated inter-dealer or inter-bank resale market. Purchases and sales of loans are generally subject to contractual restrictions that must be satisfied before a loan can be bought or sold. These restrictions may impede the Fund’s ability to buy or sell loans and may negatively impact the transaction price. It may take longer than seven days for transactions in loans to settle. The Fund may hold cash, sell investments or temporarily borrow from banks to meet short-term liquidity needs due to the extended loan settlement process, such as to satisfy redemption requests from Fund shareholders. U.S. federal securities laws afford certain protections against fraud and misrepresentation in connection with the offering or sale of a security, as well as against manipulation of trading markets for securities. The typical practice of a lender in relying exclusively or primarily on reports from the borrower may involve the risk of fraud, misrepresentation, or market manipulation by the borrower. It is unclear whether U.S. federal securities law protections are available to an investment in a loan. In certain circumstances, loans may not be deemed to be securities, and in the event of fraud or misrepresentation by a borrower, lenders may not have the protection of the anti-fraud provisions of the federal securities laws. However, contractual provisions in the loan documents may offer some protections, and lenders may also avail themselves of common-law fraud protections under applicable state law.
RiverPark Strategic Income Fund | Below Investment Grade Securities Risk (Commonly Referred To As “Junk” Bonds) Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Below Investment Grade Securities Risks (commonly referred to as “junk” bonds). The Fund may invest 100% of its assets in fixed-income instruments that are or are deemed to be the equivalent in terms of quality to securities rated below investment grade by nationally recognized statistical rating agencies and accordingly involve great risk. Such securities are regarded as predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal in accordance with the terms of the obligations and involve major risk to adverse conditions. These securities offer higher returns than bonds with higher ratings as compensation for holding an obligation of an issuer perceived to be less creditworthy. The market prices of such securities are also subject to abrupt and erratic market movements and above-average price volatility, and the spread between the bid and ask prices of such securities may be greater than those prevailing in other securities markets. Changes in economic conditions or developments regarding issuers of non-investment grade debt securities are more likely to cause price volatility and weaken the capacity of such issuers to make principal and interest payments than is the case for higher grade debt securities. In addition, the market for lower grade debt securities may be thinner and less active than for higher grade debt securities.
RiverPark Strategic Income Fund | Convertible Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Convertible Securities Risk. A convertible security is a fixed-income security (a debt instrument or a preferred stock) which may be converted at a stated price within a specified period of time into a certain quantity of the common stock of the same or a different issuer. The market value of a convertible security performs like that of a regular debt security, that is, if market interest rates rise, the value of the convertible security falls.
RiverPark Strategic Income Fund | Credit Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Credit Risk. Debt portfolios are subject to credit risk. Credit risk refers to the likelihood that an issuer will default in the payment of principal and/or interest on an instrument. Financial strength and solvency of an issuer are the primary factors influencing credit risk. In addition, lack or inadequacy of collateral or credit enhancement for a debt instrument may affect its credit risk. Credit risk may change over the life of an instrument, and debt obligations which are rated by rating agencies are often reviewed and may be subject to downgrade.
RiverPark Strategic Income Fund | Cybersecurity Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Cybersecurity Risk. With the increased use of technologies such as the Internet to conduct business, the Fund is susceptible to operational, information security, and related risks. Cyber incidents affecting the Fund or its service providers have the ability to cause disruptions and impact business operations, potentially resulting in financial losses, interference with the Fund’s ability to calculate its NAV, impediments to trading, the inability of shareholders to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs.
RiverPark Strategic Income Fund | Distressed Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Distressed Securities Risk. The Fund may invest in securities of companies that are experiencing significant financial or business difficulties, including companies involved in bankruptcy or other reorganization and liquidation proceedings. Although such investments may result in significant returns to the Fund, they involve a substantial degree of risk. Any one or all of the issuers of the securities in which the Fund may invest may be unsuccessful or not show any return for a considerable period of time. The level of analytical sophistication, both financial and legal, necessary for successful investment in companies experiencing significant business and financial difficulties is unusually high. There is no assurance that the Adviser will correctly evaluate the value of the assets collateralizing the Fund’s loans or the prospects for a successful reorganization or similar action. In any reorganization or liquidation proceeding relating to a company in which the Fund invests, the Fund may lose its entire investment or may be required to accept cash or securities with a value less than the Fund’s original investment. Under such circumstances, the returns generated from the Fund’s investments in distressed securities may not adequately compensate for the risks assumed. In addition, there is no minimum credit standard that is a prerequisite to the Fund’s investment in any instrument, and a significant portion of the obligations and preferred stock in which the Fund invests may be less than investment grade.
RiverPark Strategic Income Fund | Equity Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Equity Securities Risk. The Fund may invest in income producing equity securities. Although investments in income producing equity securities are considered safer than equity securities in general, and equities historically have been a leading choice for long-term investors, the values of stocks rise and fall depending on many factors. The stock or other security of a company may not perform as well as expected, and may decrease in value, because of factors related to the company (such as poorer than expected earnings or certain management decisions) or to the industry in which the company is engaged (such as a reduction in the demand for products or services in a particular industry). Market and economic factors may adversely affect securities markets generally, which could in turn adversely affect the value of the Fund’s investments, regardless of the performance or expected performance of companies in which the Fund invests.
RiverPark Strategic Income Fund | Fixed Income Securities Market Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock
Fixed Income Securities Market Risk. Difficult conditions in the broader financial markets have in the past resulted in a temporary but significant contraction in liquidity for fixed income securities. Liquidity relates to the ability of the Fund to sell its investments in a timely manner at a price approximately equal to its value on the Fund’s books. To the extent that the market for fixed income securities suffers such a contraction, securities that were considered liquid at the time of investment could become temporarily illiquid, and the Adviser may experience delays or difficulty in selling assets at the prices at which the Fund carries such assets, which may result in a loss to the Fund. There is no way to predict reliably when such market conditions could re-occur or how long such conditions could persist.
In the event of a severe market contraction precipitated by general market turmoil, economic conditions, changes in prevailing interest rates or otherwise, coupled with extraordinary levels of Fund shareholder redemption requests, the Fund may have to consider selling its holdings at a loss including at prices below the current value on the Fund’s books, borrowing money to satisfy redemption requests in accordance with the Fund’s borrowing policy or postponing payment of redemption requests for up to seven days or longer, as permitted by applicable law, or other extraordinary measures. In addition, if the Fund needed to sell large blocks of investments to meet shareholder redemption requests or to raise cash, those sales could further reduce prices, particularly for lower-rated and unrated securities.
In response to rising inflation, the Federal Reserve began raising short-term interest rates in 2022 with the potential for further rate increases. Uncertainty regarding the ability of the Federal Reserve to successfully control inflation, the potential for incremental rate increases, and the full impact of prior rate increases may negatively impact fixed income security prices and increase market volatility. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities.
Fixed Income Securities Risk. The Fund invests a significant portion of its assets in fixed income securities. Fixed income securities are subject to credit risk and market risk, including interest rate risk. Credit risk is the risk of the issuer’s inability to meet its principal and interest payment obligations. Market risk is the risk of price volatility due to such factors as interest rate sensitivity, market perception of the creditworthiness of the issuer and general market liquidity. There is no limitation on the maturities of fixed income securities in which the Fund invests. Securities having longer maturities generally involve greater risk of fluctuations in value resulting from changes in interest rates.
RiverPark Strategic Income Fund | Foreign Investments Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Foreign Investments Risk. Investments in fixed income securities of U.S. and foreign issuers and instruments that are linked to fixed income securities (collectively, “Credit-Related Instruments”) involve certain risks not generally associated with investments in the securities of U.S. issuers, including changes in currency exchange rates, unstable political, social and economic conditions, a lack of adequate or accurate company information, differences in the way securities markets operate, less secure international banks or securities depositories than those in the U.S. and foreign controls on investment. In addition, individual international country economies may differ favorably or unfavorably from the U.S. economy in such respects as growth of gross domestic product, rates of inflation, capital reinvestment, resources, self-sufficiency and balance of payments position. Income earned on foreign investments may be subject to foreign withholding taxes.
RiverPark Strategic Income Fund | Forward Currency Contracts Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock
Forward Currency Contracts. The Fund may enter into forward currency contracts. A forward currency contract is an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days from the date of the contract agreed upon by the parties, at a price set at the time of the contract. For example, the Fund might purchase a particular currency or enter into a forward currency contract to preserve the U.S. dollar price of securities it intends to or has contracted to purchase. Alternatively, it might sell a particular currency on either a spot or forward basis to hedge against an
anticipated decline in the dollar value of securities it intends to or has contracted to sell. Although this strategy could minimize the risk of loss due to a decline in the value of the hedged currency, it could also limit any potential gain from an increase in the value of the currency.
RiverPark Strategic Income Fund | General Market Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock General Market Risk. Certain securities selected for the Fund’s portfolio may be worth less than the price originally paid for them, or less than they were worth at an earlier time.
RiverPark Strategic Income Fund | High Portfolio Turnover Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock High Portfolio Turnover Risk. The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Fund’s performance.
RiverPark Strategic Income Fund | Illiquid Investments Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Illiquid Investments Risk. Illiquid investments include any investment that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or dispositions significantly changing the market value of the investment, and include repurchase agreements maturing in more than seven days. The Fund’s investments in certain types of fixed income securities such as bank loans, mortgage-backed securities and below investment grade fixed income securities could have the effect of increasing the amount of the Fund’s assets invested in illiquid investments if market conditions develop that make such investments difficult to sell. Liquidity risk may be higher in a rising interest rate environment, when the value and liquidity of fixed-income securities generally decline. Illiquid investments involve the risk that the securities will not be able to be sold at the time desired by the Adviser or at prices approximating the value at which the Fund is carrying the securities.
RiverPark Strategic Income Fund | Interest Rate Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Interest Rate Risk. The prices of securities in general and fixed-income securities in particular tend to be sensitive to interest rate fluctuations. Increases in interest rates can result in significant declines in the prices of fixed-income securities. Securities with floating interest rates generally are less sensitive to interest rate changes but may decline in value if their interest rates do not rise as much, or as quickly, as interest rates in general. The negative impact on fixed income securities generally from rate increases, regardless of the cause, could be swift and significant, which could result in losses by the Fund, even if anticipated by the Adviser. Starting in 2022, the Federal Reserve began to increase interest rates in an effort to combat inflation which has resulted in periods of volatility.
RiverPark Strategic Income Fund | Management Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Management Risk. Investment strategies employed by the Adviser in selecting investments for the Fund may not result in an increase in the value of your investment or in overall performance equal to other investments.
RiverPark Strategic Income Fund | Preferred Stock Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Preferred Stock Risk. Preferred stocks may be more volatile than fixed income securities and are more correlated with the issuer’s underlying common stock than fixed income securities. Additionally, the dividend on a preferred stock may be changed or omitted by the issuer, and participation in the growth of an issuer may be limited.
RiverPark Strategic Income Fund | Recent Market Events Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock
Recent Market Events Risk. U.S. and international markets have experienced and may continue to experience significant periods of volatility in recent years and months due to a number of economic, political and global macro factors including uncertainty regarding inflation and central banks’ interest rate increases, the possibility of a national or global recession, trade tensions, political events, the war between Russia and Ukraine, significant conflict between Israel and Hamas in the Middle East, and the impact of the coronavirus (COVID-19) global pandemic. The impact of COVID-19 may last for an extended period
of time. As a result of continuing political tensions and armed conflicts, including the war between Ukraine and Russia, the U.S. and the European Union imposed sanctions on certain Russian individuals and companies, including certain financial institutions, and have limited certain exports and imports to and from Russia. The war has contributed to recent market volatility and may continue to do so. Continuing market volatility as a result of recent market conditions or other events may have an adverse effect on the performance of the Fund.
RiverPark Strategic Income Fund | Short Sales Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Short Sales Risk. A short sale is the sale by the Fund of a security which it does not own in anticipation of purchasing the same security in the future at a lower price to close the short position. A short sale will be successful if the price of the shorted security decreases. However, if the underlying security goes up in price during the period in which the short position is outstanding, the Fund will realize a loss. The risk on a short sale is unlimited because the Fund must buy the shorted security at the higher price to complete the transaction. Therefore, short sales may be subject to greater risks than investments in long positions. With a long position, the maximum sustainable loss is limited to the amount paid for the security plus the transaction costs, whereas there is no maximum attainable price of the shorted security. The Fund would also incur increased transaction costs associated with selling securities short. In addition, if the Fund sells securities short, it must maintain a segregated account with its custodian containing cash or high-grade securities equal to (i) the greater of the current market value of the securities sold short or the market value of such securities at the time they were sold short, less (ii) any collateral deposited with the Fund’s broker (not including the proceeds from the short sales).
RiverPark Strategic Income Fund | Sovereign Debt Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock Sovereign Debt Risk. The Fund may invest in securities issued or guaranteed by foreign governmental entities (known as sovereign debt securities). These investments are subject to the risk of payment delays or defaults, due, for example, to cash flow problems, insufficient foreign currency reserves, political considerations, large debt positions relative to the country’s economy, or failure to implement economic reforms. There is no legal or bankruptcy process for collecting sovereign debt.
RiverPark Strategic Income Fund | SPACs Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk Narrative [Text Block] rr_RiskTextBlock SPACs Risk. The Fund invests in equity securities of SPACs, which raise assets to seek potential business combination opportunities. Unless and until a business combination is completed, a SPAC generally invests its assets in U.S. government securities, money market securities, and cash. Because SPACs have no operating history or ongoing business other than seeking a business combination, the value of their securities is particularly dependent on the ability of the entity’s management to identify and complete a profitable business combination. There is no guarantee that the SPACs in which the Fund invests will complete a business combination or that any business combination that is completed will be profitable. The market perception of a SPAC’s ability to complete a business combination could materially impact the market value of the SPAC’s securities. Public stockholders of SPACs may not be afforded a meaningful opportunity to vote on a proposed initial business combination because certain stockholders, including stockholders affiliated with the management of the SPAC, may have sufficient voting power, and a financial incentive, to approve such a transaction without support from public stockholders. As a result, a SPAC may complete a business combination even though a majority of its public stockholders do not support such a combination. Some SPACs may pursue a business combination only within certain industries or regions, which may increase the volatility of their prices.

[3] The returns shown in the bar chart are for Institutional Class shares of the Fund. Retail Class shares would have substantially
similar annual returns because the shares are invested in the same portfolio of securities and the annual returns would differ only
to the extent that the classes do not have the same expenses.

[6] Pursuant to an operating expense limitation agreement between CrossingBridge Advisors, LLC (the “Adviser”), the Fund’s investment adviser, and the Trust, on behalf of the Fund, the Adviser has agreed to waive its management fees and/or reimburse Fund expenses to ensure that Total Annual Fund Operating Expenses (exclusive of front-end or contingent deferred loads, Rule 12b-1 plan fees, shareholder servicing plan fees, leverage (i.e., any expenses incurred in connection with borrowings made by the Fund) interest (including interest incurred in connection with bank and custody overdrafts), brokerage commissions and other transactional expenses, expenses incurred in connection with any merger or reorganization, dividends or interest on short positions, acquired fund fees and expenses or extraordinary expenses such as litigation (collectively “Excluded Expenses”)) do not exceed 0.80% of the Fund’s average annual net assets, through at least January 31, 2025. To the extent the Fund incurs Excluded Expenses, Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement may be greater than 0.80%. The operating expense limitation agreement can be terminated only by, or with the consent of, the Board of Trustees. The Adviser may request recoupment of previously waived fees and paid expenses from the Fund up to three years from the date such fees and expenses were waived or paid, subject to the operating expense limitation agreement, if such reimbursement will not cause the Fund’s expense ratio, after recoupment has been taken into account, to exceed the lesser of: (1) the expense limitation in place at the time of the waiver and/or expense payment; or (2) the expense limitation in place at the time of the recoupment.
