EMERALD BANKING & FINANCE EVOLUTION FUND | Active Management Risk  
Prospectus [Line Items]  
Risk [Text Block]

Active Management Risk: The Fund is actively managed using proprietary investment strategies and processes. There can be no guarantee that these strategies and processes will be successful or that the Fund will achieve its investment objective.

EMERALD BANKING & FINANCE EVOLUTION FUND | Affiliated ETF Risk  
Prospectus [Line Items]  
Risk [Text Block]

Affiliated ETF Risk: Affiliated ETF risk is the risk that the Adviser may select Underlying ETF investments for the Fund based on its own financial interests rather than the Fund’s interests. The Adviser may be subject to potential conflicts of interest in selecting the Underlying ETFs because the fees paid to the Adviser by some Underlying ETFs may be higher than other ETFs, or the Underlying ETFs may be in need of assets to enhance their appeal to other investors, liquidity, and trading and/or to enable them to carry out their investment strategies. However, the Adviser is a fiduciary to the Fund and is legally obligated to act in the Fund’s best interest when selecting Underlying ETFs.

EMERALD BANKING & FINANCE EVOLUTION FUND | Concentration Risk  
Prospectus [Line Items]  
Risk [Text Block]

Concentration Risk: The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in a particular issue, issuer or issuers, country, market segment, industries, project types, or asset class.

EMERALD BANKING & FINANCE EVOLUTION FUND | Cyber Security Risk  
Prospectus [Line Items]  
Risk [Text Block]

Cyber Security Risk: Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, Adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The Fund and Adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers, and such third-party service providers may have limited indemnification obligations to the Fund or Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

EMERALD BANKING & FINANCE EVOLUTION FUND | Equity Securities Risk  
Prospectus [Line Items]  
Risk [Text Block]

Equity Securities Risk: The Fund is designed for investors who can accept the risks of investing in a portfolio with significant holdings of equity securities. Equity securities tend to be more volatile than other investment choices, such as debt and money market instruments. The value of your investment may decrease in response to overall stock market movements or the value of individual securities held by the Fund.

EMERALD BANKING & FINANCE EVOLUTION FUND | Foreign Market and Trading Risk  
Prospectus [Line Items]  
Risk [Text Block]

Foreign Market and Trading Risk: The trading markets for many foreign securities are not as active as U.S. markets and may have less governmental regulation and oversight. Foreign markets also may have clearance and settlement procedures that make it difficult for the Fund to buy and sell securities. These factors could result in a loss to the Fund by causing the Fund to be unable to dispose of an investment or to miss an attractive investment opportunity, or by causing Fund assets to be uninvested for some period of time. In addition, where all or portion of the Fund’s underlying securities trade in a foreign market that is closed when the market in which the Fund’s Shares are listed is open for trading, there may be changes between the last quote of the underlying securities’ value in the closed foreign market and the value of such underlying securities during the Fund’s domestic trading day.

EMERALD BANKING & FINANCE EVOLUTION FUND | Growth Stocks Risk  
Prospectus [Line Items]  
Risk [Text Block]

Growth Stocks Risk: Growth stocks are typically priced higher than other stocks, in relation to earnings and other measures, because investors believe they have more growth potential. This potential may or may not be realized and, if it is not realized, may result in a loss to the Fund. Growth stock prices also tend to be more volatile than the overall market. Because different types of stocks go out of favor with investors depending on market and economic conditions, the Fund’s return may be adversely affected during a market downturn and when growth stocks are out of favor.

EMERALD BANKING & FINANCE EVOLUTION FUND | Investment Companies and ETFs Risk  
Prospectus [Line Items]  
Risk [Text Block]

Investment Companies and ETFs Risk: The Fund’s investment performance may be affected by the investment performance of the underlying funds in which the Fund may invest. Investing in other investment companies, including ETFs, may result in duplication of expenses, including advisory fees, in addition to the Fund’s own expenses. The risk of owning an investment company or ETF generally reflects the risks of owning the underlying investments the investment company or ETF holds. The Fund may incur brokerage fees in connection with its purchase of ETF shares. Certain ETFs may be thinly traded and experience large spreads between the “ask” price quoted by a seller and the “bid” price offered by a buyer. The existence of extreme market volatility or potential lack of an active trading market for an ETF’s shares could result in such shares trading at a significant premium or discount to their NAV.

EMERALD BANKING & FINANCE EVOLUTION FUND | Liquidity Risk  
Prospectus [Line Items]  
Risk [Text Block]

Liquidity Risk: Liquidity risk is the risk that a limited market for a security may make it difficult for that security to be sold at an advantageous time or price, which could prevent the Fund from selling the security at the approximate price that it is valued or the time it desires to sell. Liquidity risk may be magnified during times of instability in the credit markets, rising interest rates, high selling activity, or other circumstances where investor redemptions from fixed income mutual funds may be higher than normal. The capacity of traditional dealers to engage in fixed income trading has not kept pace with the fixed income market’s growth, causing dealer inventories to be at or near historical lows relative to market size. The reduction in dealer inventories could lead to decreased liquidity, increased volatility and wider spreads, which may become exacerbated during periods of economic or political stress. Lower rated securities may be subject to greater levels of liquidity risk. If a fixed income security is downgraded or declines in price, the market demand may be limited, making that security difficult to sell. Additionally, the market for certain fixed-income securities may become illiquid under adverse market or economic conditions, independent of any specific adverse changes in the conditions of a particular issuer.

EMERALD BANKING & FINANCE EVOLUTION FUND | Market Risk  
Prospectus [Line Items]  
Risk [Text Block]

Market Risk: The Fund is subject to market risk, which is the risk that the Fund’s share price will fluctuate as market prices fluctuate. At times there may be an imbalance of supply and demand in the fixed income markets which could result in greater price volatility, less liquidity, wider trading spreads and a lack of price transparency. Decisions by the Federal Reserve on interest rate policy and the potential market reaction to these initiatives can have a significant effect on the value of fixed-income securities. The Fund is also subject to management risk, which is the risk that the Adviser’s analysis of economic conditions and expectations regarding interest rate changes may fail to produce the intended results. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The Fund may not be appropriate for use as a complete investment program. Events such as war, military conflict, acts of terrorism, social unrest, natural disasters, recessions, inflation, rapid interest rate changes, supply chain disruptions, sanctions, the spread of infectious illness or other public health threats could also significantly impact the Fund and its investments.

EMERALD BANKING & FINANCE EVOLUTION FUND | REIT Risk  
Prospectus [Line Items]  
Risk [Text Block]

REIT Risk: REITs may be affected by economic forces and other factors related to the real estate industry. These risks include possible declines in the value of real estate, possible lack of availability of mortgage funds and unexpected vacancies of properties. REITs are also subject to heavy cash flow dependency, defaults by borrowers, self liquidation, interest rate risks (especially mortgage REITS) and liquidity risks. REITs that invest in real estate mortgages are also subject to prepayment risk. Investing in REITs may involve risks similar to those associated with investing in small capitalization companies. REITs may have limited financial resources, may trade less frequently and in a limited volume, engage in dilutive offerings, and may be subject to more abrupt or erratic price movements than larger company securities. Historically, small capitalization stocks, such as REITs, have been more volatile in price than the larger capitalization stocks included in the S&P 500® Index. In addition, REITs could possibly fail to (i) qualify for favorable tax treatment under applicable tax law, or (ii) maintain their exemptions from registration under the Investment Company Act of 1940, as amended (the “1940 Act”). The Fund will indirectly bear its proportionate share of any expenses, including management fees, paid by an externally managed REIT in which it invests.

EMERALD BANKING & FINANCE EVOLUTION FUND | Sector Risk  
Prospectus [Line Items]  
Risk [Text Block]

Sector Risk: To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

oBanking Sector Risk. The banking sector can be adversely affected by legislation, regulation, competition, declines in economic conditions, corporate and consumer debt defaults, changing interest rates, and instability in the financial markets in general. Credit losses resulting from financial difficulties of borrowers can have a significant negative impact. Changes in legislation in past years may have tended to increase competition in the industry. The stability and profitability of this sector depends significantly upon the availability and cost of capital funds.

 

  o Financial Sector Risk. The Fund may be susceptible to adverse economic or regulatory occurrences affecting the financial sector. Financial services companies are subject to extensive government regulation and, as a result, their profitability may be affected by new regulations or regulatory interpretations. Changes in interest rates can have a disproportionate effect on the financial sector and financial services companies whose securities the Fund may purchase may themselves have concentrated portfolios, which makes them vulnerable to economic conditions that affect that sector. Financial services companies have also been affected by increased competition, which could adversely affect the profitability or viability of such companies.
EMERALD BANKING & FINANCE EVOLUTION FUND | Small and Medium Capitalization Issuers Risk  
Prospectus [Line Items]  
Risk [Text Block]

Small and Medium Capitalization Issuers Risk: Investing in equity securities of small and medium capitalization companies often involves greater risk than is customarily associated with investments in larger capitalization companies. This increased risk may be due to the greater business risks of smaller size, limited markets and financial resources, narrow product lines and frequent lack of depth of management. The securities of smaller companies are often traded in the over-the-counter market and even if listed on a national securities exchange may not be traded in volumes typical for that exchange. Consequently, the securities of smaller companies are less likely to be liquid, may have limited market stability, and may be subject to more abrupt or erratic market movements than securities of larger, more established companies or the market averages in general.

Sector Risk: To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

oHealth Care Sector Risk: Companies in the health care sector are subject to extensive government regulation and their profitability can be significantly affected by restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure (including price discounting), limited product lines and an increased emphasis on the delivery of healthcare through outpatient services. Companies in the health care sector are heavily dependent on obtaining and defending patents, which may be time consuming and costly, and the expiration of patents may also adversely affect the profitability of these companies. Health care companies are also subject to extensive litigation based on product liability and similar claims. In addition, their products can become obsolete due to industry innovation, changes in technologies or other market developments. Many new products in the health care sector require significant research and development and may be subject to regulatory approvals, all of which may be time consuming and costly with no guarantee that any product will come to market.

 

  o Technology Companies Risk: Technology companies and companies that rely heavily on technological advances may have limited product lines, markets, financial resources and personnel. These companies may face rapid product obsolescence, as well as unexpected risks and costs related to new product introduction and technological developments, such as artificial intelligence and machine learning. Technology companies may be adversely affected by disruptions to supply chains and distribution networks, as well as issues at third-party partners. They are heavily dependent on patent and other intellectual property rights, and the loss or impairment of these rights may adversely affect their profitability. Technology companies may face increased government scrutiny and may be subject to adverse governmental or legal action. These companies may also be adversely affect by, among other things, actual or perceived security vulnerabilities or other defects in their products and services, which may result in lawsuits, government enforcement actions and other remediation costs.

 

  o Industrial Sector Risk: Companies in the industrial sector may be adversely affected by changes in the supply and demand for products and services, product obsolescence or discontinuance, claims for environmental damage or product liability and changes in general economic conditions, among other factors.

Risk [Text Block]
Concentration Risk. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund invests more heavily in a particular issue, issuer or issuers, country, market segment, industries, project types, or asset class.
F/m Emerald Special Situations ETF | Cyber Security Risk  
Prospectus [Line Items]  
Risk [Text Block]
Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the Adviser, the Sub-Adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The Fund, the Adviser, and the Sub-Adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers and such third-party service providers may have limited indemnification obligations to the Fund, the Adviser or the Sub-Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.
F/m Emerald Special Situations ETF | Equity Securities Risk

Equity Securities Risk. The Fund may invest in, or have exposure to, equity securities. Equity securities tend to be more volatile than other investment choices, such as debt and money market instruments. The value of your investment may decrease in response to overall stock market movements or the value of individual securities.
F/m Emerald Special Situations ETF | Liquidity Risk  
Prospectus [Line Items]  
Risk [Text Block]
Liquidity Risk. Liquidity risk is the risk, due to certain investments trading in lower volumes or to market and economic conditions that the Fund may be unable to find a buyer for its investments when it seeks to sell them or to receive the price it expects based on the Fund’s valuation of the investments. Events that may lead to increased redemptions, such as market disruptions, may also negatively impact the liquidity of the Fund’s investments when it needs to dispose of them. If the Fund is forced to sell its investments at an unfavorable time and/or under adverse conditions in order to meet redemption requests, such sales could negatively affect the Fund. Liquidity issues may also make it difficult to value the Fund’s investments.
F/m Emerald Special Situations ETF | Market Risk  
Prospectus [Line Items]  
Risk [Text Block]
Market Risk. The NAV of the Fund will change with changes in the market value of its portfolio positions. Investors may lose money. The value of investments held by the Fund may increase or decrease in response to economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets.

Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Technology Sector Risk. To the extent the Fund invests a significant portion of its assets in technology companies, the Fund is particularly vulnerable to factors affecting the technology section. In addition to market or economic factors, companies in the technology sector and companies that rely heavily on technology are particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition.
F/m Emerald Special Situations ETF | Convertible Securities Risk  
Prospectus [Line Items]  
Risk [Text Block]
Convertible Securities Risk. Securities that can be converted into common stock, such as certain securities and preferred stock, are subject to the usual risks associated with fixed income investments, such as interest rate risk and credit risk. In addition, because they react to changes in the value of the equity securities into which they will convert, convertible securities are also subject to the risks associated with equity securities.
F/m Emerald Special Situations ETF | Currency Risk  
Prospectus [Line Items]  
Risk [Text Block]
Currency Risk. Currency risk results from changes in the rate of exchange between the currency of the country in which a foreign company is domiciled or keeps its books and the U.S. dollar. Whenever the Fund holds securities valued in a foreign currency or holds the currency itself in connection with its purchases and sales of foreign securities, changes in the exchange rate add to or subtract from the value of the investment in U.S. dollars. The Fund generally does not seek to hedge currency risk, and although the Sub-Adviser considers currency risks as part of its investment process, its judgments in this regard may not always be correct.
F/m Emerald Special Situations ETF | Distributed Ledger Technology (“DLT”) and Blockchain Investments Risk  
Prospectus [Line Items]  
Risk [Text Block]
Distributed Ledger Technology (“DLT”) and Blockchain Investments Risk. The Fund may invest in companies listed on U.S. and Canadian exchanges that are engaged in the use of, or have exposure to, DLT and blockchain. The mechanics of using DLT, including blockchain, to transact in assets, including securities, is relatively new and untested and there is no assurance that widespread adoption will occur. DLT and blockchain are subject to a rapidly-evolving regulatory landscape in the United States and in other countries, which might include security, privacy or other regulatory concerns that could negatively impact the companies in which the Fund invests. Companies in which the Fund invests may also be subject to the risk of fraud and cybersecurity threats and intellectual property claims. A significant disruption of internet connectivity could impede the functionality of these technologies and could adversely affect the Fund.
F/m Emerald Special Situations ETF | Depositary Receipts Risk  
Prospectus [Line Items]  
Risk [Text Block]
Depositary Receipts Risk. The Fund may purchase depositary receipts (American Depositary Receipts (“ADRs”), European Depositary receipts (“EDRs”), Global Depositary receipts (“GDRs”), and Non-Voting Depositary Receipts (“NVDRs”)) to facilitate its investments in foreign securities. By investing in ADRs rather than investing directly in the securities of foreign issuers, the Fund can avoid currency risks during the settlement period for purchase and sales. However, ADRs do not eliminate all the risks inherent in investing in the securities of foreign issuers. Depositary receipts may be issued in a sponsored program, in which an issuer has made arrangements to have its securities traded in the form of depositary receipts, or in an unsponsored program, in which the issuer may not be directly involved. The holders of depositary receipts that are unsponsored generally bear various costs associated with the facilities, while a larger portion of the costs associated with sponsored depositary receipts are typically borne by the foreign issuers.
F/m Emerald Special Situations ETF | Emerging Markets Risk  
Prospectus [Line Items]  
Risk [Text Block]
Emerging Markets Risk. The Fund may have exposure to securities in emerging markets. Investment in emerging market securities involves greater risk than that associated with investment in foreign securities of developed foreign countries. These risks include volatile currency exchange rates, periods of high inflation, increased risk of default, greater social, economic and political uncertainty and instability, less governmental supervision and regulation of securities markets, weaker auditing and financial reporting standards, lack of liquidity in the markets, and the significantly smaller market capitalizations of emerging market issuers. The information available about an emerging market issuer may be less reliable than for comparable issuers in more developed capital markets. In addition, investments in certain emerging markets are subject to an elevated risk of loss resulting from market manipulation and the imposition of exchange controls (including repatriation restrictions). The legal rights and remedies available for investors in emerging markets may be more limited than the rights and remedies available in the U.S., and the ability of U.S. authorities (e.g., SEC and the U.S. Department of Justice) to bring actions against bad actors in emerging markets may be limited.
F/m Emerald Special Situations ETF | ETF Risk  
Prospectus [Line Items]  
Risk [Text Block]
ETF Risk. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks: “Authorized Participants, Market Makers and Liquidity Providers Concentration Risk,” “Cash Transactions Risk,” “Secondary Market Trading Risk,” and “Shares May Trade at Prices Other Than Net Asset Value (“NAV”) Risk.”

 

Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. Only an authorized participant (“AP”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of financial institutions that are institutional investors and may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to its net asset value (“NAV”) and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. These events, among others, may lead to the Shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than the NAV when you buy Shares in the secondary market, and you may receive less (or more) than NAV when you sell those Shares in the secondary market. A diminished market for an ETF’s shares substantially increases the risk that a shareholder may pay considerably more or receive significantly less than the underlying value of the ETF shares bought or sold. In periods of market volatility, APs, market makers and/or liquidity providers may be less willing to transact in Shares.

 

Cash Transactions Risk. Unlike certain ETFs, the Fund may effect its creations and redemptions partially or wholly for cash rather than on an in-kind basis. Because of this, the Fund may incur costs such as brokerage costs or be unable to realize certain tax benefits associated with in-kind transfers of portfolio securities that may be realized by other ETFs. These costs may decrease the Fund’s NAV to the extent that the costs are not offset by a transaction fee payable by an AP. Shareholders may be subject to tax on gains they would not otherwise have been subject to and/ or at an earlier date than if the Fund had effected redemptions wholly on an in-kind basis.

 

Secondary Market Trading Risk. Although Shares are listed on a national securities exchange, the Nasdaq Stock Market LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted. Trading may be halted because of market conditions or for reasons that, in the view of the Exchange, make trading in the Fund inadvisable. These may include: (a) the extent to which trading is not occurring in the securities and/or the financial instruments composing the Fund’s Portfolio; or (b) whether other unusual conditions or circumstances detrimental to the maintenance of a fair and orderly market are present. During periods of market stress, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount). This risk is heightened in times of market volatility or periods of steep market declines.

 

Shares May Trade at Prices Other Than NAV Risk. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. There is a risk that market prices for Fund Shares will vary significantly from the Fund’s NAV. Where all or portion of the Fund’s underlying securities trade in a foreign market that is closed when the market in which the Fund’s Shares are listed is open for trading, there may be changes between the last quote of the underlying securities’ value in the closed foreign market and the value of such underlying securities during the Fund’s domestic trading day.
F/m Emerald Special Situations ETF | Financial Technology Risk

Financial Technology Risk. The Fund may invest in companies engaged in financial technology-related activities. Companies that are developing financial technologies that seek to disrupt or displace established financial institutions generally face competition from much larger and more established firms. Financial technology companies may not be able to capitalize on their disruptive technologies if they face political and/or legal attacks from competitors, industry groups or local and national governments. Laws generally vary by country, creating some challenges to achieving scale. These financial technology companies may not currently derive any revenue, and there is no assurance that such company will derive any revenue from innovative technologies in the future. Additionally, financial technology companies may be adversely impacted by potential rapid product obsolescence, cybersecurity attacks, increased regulatory oversight and disruptions in the technology they depend on.
F/m Emerald Special Situations ETF | Foreign Investments Risk  
Prospectus [Line Items]  
Risk [Text Block]
Foreign Investments Risk. The Fund may invest in the securities of foreign companies. Investing in securities of foreign companies involves risks generally not associated with investments in the securities of U.S. companies, including the risks associated with fluctuations in foreign currency exchange rates, less stringent investor protections, unreliable and untimely information about issuers, and political and economic instability. Foreign securities in which the Fund invests may be traded in markets that close before the time that the Fund calculates its NAV. Furthermore, certain foreign securities in which the Fund invests may be listed on foreign exchanges that trade on weekends or other days when the Fund does not calculate its NAV. As a result, the value of the Fund’s holdings may change on days when shareholders are not able to purchase or redeem the Fund’s shares.
F/m Emerald Special Situations ETF | Growth Stock Risk  
Prospectus [Line Items]  
Risk [Text Block]
Growth Stock Risk. Growth stocks are typically priced higher than other stocks, in relation to earnings and other measures, because investors believe they have more growth potential. This potential may or may not be realized and, if it is not realized, may result in a loss to the Fund. Growth stock prices also tend to be more volatile than the overall market. Because different types of stocks go out of favor with investors depending on market and economic conditions, the Fund’s return may be adversely affected during a market downturn and when growth stocks are out of favor.
F/m Emerald Special Situations ETF | Illiquid Investments Risk  
Prospectus [Line Items]  
Risk [Text Block]
Illiquid Investments Risk. Investing in illiquid investments is subject to certain risks, such as limitations on resale and uncertainty in determining valuation. Limitations on resale may adversely affect the marketability of portfolio securities and the Fund might be unable to dispose of restricted or other illiquid investments promptly or at reasonable prices and might thereby experience difficulty satisfying redemptions within seven days. The Fund might, in order to dispose of restricted securities, have to register securities resulting in additional expense and delay. Adverse market conditions could impede such a public offering of such securities. Less liquid securities that the Fund may want to invest in may be difficult or impossible to purchase. Federal banking regulations may also cause certain dealers to reduce their inventories of certain securities, which may further decrease the Fund’s ability to buy or sell such securities.
F/m Emerald Special Situations ETF | Initial Public Offerings (“IPOs”) Risk  
Prospectus [Line Items]  
Risk [Text Block]
Initial Public Offerings (“IPOs”) Risk. Special risks associated with IPOs may include, among others, the fact that there may be only a limited number of shares available for trading. The market for those securities may be unseasoned. The issuer may have a limited operating history. These factors may contribute to price volatility. The limited number of shares available for trading in some IPOs may also make it more difficult for the Fund to buy or sell significant amounts of shares without an unfavorable impact on prevailing prices.
F/m Emerald Special Situations ETF | Issuer Risk  
Prospectus [Line Items]  
Risk [Text Block]
Issuer Risk. The performance of the Fund depends on the performance of individual securities or other assets to which the Fund has exposure. The value of securities or other assets may decline, or perform different from the market as a whole, due to changes in the financial condition or credit rating of the issuer or counterparty.
F/m Emerald Special Situations ETF | Large-Capitalization Investing Risk  
Prospectus [Line Items]  
Risk [Text Block]
Large-Capitalization Investing Risk. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion.
F/m Emerald Special Situations ETF | Management Risk  
Prospectus [Line Items]  
Risk [Text Block]
Management Risk. The Fund is subject to management risk as an actively-managed investment portfolio. The Sub- Adviser’s investment approach may fail to produce the intended results. The Sub-Adviser has limited experience in managing ETFs. Accordingly, shareholders in the Fund bear the risk that the Sub-Adviser’s limited experience may impact its effectiveness.
F/m Emerald Special Situations ETF | Micro-Cap and Small Cap Companies Risk  
Prospectus [Line Items]  
Risk [Text Block]
Micro-Cap and Small Cap Companies Risk. Investments in securities of micro- and small-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of larger-capitalization companies. The securities of micro- and small-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than larger capitalization stocks or the stock market as a whole. Some micro- and small-capitalization companies have limited product lines, markets, and financial and managerial resources and tend to concentrate on fewer geographical markets relative to larger capitalization companies. There is typically less publicly available information concerning smaller-capitalization companies than for larger, more established companies. Micro- and small-capitalization companies also may be particularly sensitive to changes in interest rates, government regulation, borrowing costs and earnings.
F/m Emerald Special Situations ETF | Mid-Capitalization Companies Risk  
Prospectus [Line Items]  
Risk [Text Block]
Mid-Capitalization Companies Risk. The securities of mid-capitalization companies may involve greater risks than do investments in larger, more established companies. The prices of securities of mid-cap companies tend to be more vulnerable to adverse developments specific to a company or its industry, or the securities markets generally, than are securities of larger capitalization companies.
F/m Emerald Special Situations ETF | Operational Risk  
Prospectus [Line Items]  
Risk [Text Block]
Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties, or other third parties, failed or inadequate processes or technology or systems failures. The Fund and the Adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address significant operational risks.
F/m Emerald Special Situations ETF | Preferred Stock Risk  
Prospectus [Line Items]  
Risk [Text Block]
Preferred Stock Risk. Preferred stocks are subject to the risks of equity securities generally and also risks associated with fixed-income securities, such as interest rate risk. A company’s preferred stock generally pays dividends only after the company makes required payments to creditors. As a result, the value of a company’s preferred stock will react more strongly than bonds and other debt to actual or perceived changes in the company’s financial condition or prospects.
F/m Emerald Special Situations ETF | Private Placements Risk  
Prospectus [Line Items]  
Risk [Text Block]
Private Placements Risk. Investments in private placements could decrease the Fund’s liquidity profile or prevent the Fund from disposing of such securities promptly at advantageous prices. Private placements may be less liquid than other investments because such securities may not always be readily sold in broad public markets and may have no active trading market. As a result, they may be difficult to value because market quotations may not be readily available, and the Fund might be unable to dispose of such securities promptly or at prices reflecting their true value. Transaction costs may be higher for these securities, and the Fund may only get limited information about the issuer of a private placement security, so it may be less able to anticipate a loss.
F/m Emerald Special Situations ETF | REITs Risk  
Prospectus [Line Items]  
Risk [Text Block]
REITs Risk. Real estate investment trusts (“REITs”) may be affected by economic forces and other factors related to the real estate industry. These risks include possible declines in the value of real estate, possible lack of availability of mortgage funds and unexpected vacancies of properties. REITs are also subject to heavy cash flow dependency, defaults by borrowers, self-liquidation, interest rate risks (especially mortgage REITS) and liquidity risks. REITs that invest in real estate mortgages are also subject to prepayment risk. Investing in REITs may involve risks similar to those associated with investing in small capitalization companies. REITs may have limited financial resources, may trade less frequently and in a limited volume, engage in dilutive offerings, and may be subject to more abrupt or erratic price movements than larger company securities.

 

Historically, small capitalization stocks, such as REITs, have been more volatile in price than the larger capitalization stocks included in the S&P 500® Index. In addition. REITs could possibly fail to (i) qualify for favorable tax treatment under applicable tax law, or (ii) maintain their exemptions from registration under the 1940 Act. The Fund will indirectly bear its proportionate share of any expenses, including management fees, paid by an externally managed REIT in which it invests.

Risk of Investing in the United States. Certain changes in the United States economy, such as when the economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.
F/m Emerald Special Situations ETF | Securities issued by Other Investment Companies Risk  
Prospectus [Line Items]  
Risk [Text Block]
Securities issued by Other Investment Companies Risk. The Fund may invest in shares of other investment companies, including other mutual funds, money market funds, exchange-traded funds, exchange-traded products, holding company depository receipt (“HOLDRs”), unit investment trusts, and closed-end funds, to gain exposure to a particular portion of the market rather than purchase securities directly. Shareholders of the Fund will indirectly be subject to the fees and expenses of the other investment companies in which the Fund invests and these fees and expenses are in addition to the fees and expenses that Fund shareholders directly bear in connection with the Fund’s own operations. In addition, shareholders will be exposed to the investment risks associated with investments in the other investment companies. The SEC has adopted revisions to the rules permitting funds to invest in other investment companies. While Rule 12d1-4 permits more types of fund of fund arrangements without reliance on an exemptive order or no-action letters, it imposes new conditions, including limits on control and voting of acquired funds’ shares, evaluations and findings by investment advisers, fund investment agreements, and limits on most three-tier fund structures. Rule 12d1-4 went into effect on January 19, 2021. The rescission of the applicable exemptive orders and the withdrawal of the applicable no-action letters was effective on January 19, 2022. These regulatory changes may adversely impact the Fund’s investment strategies and operations.
F/m Emerald Special Situations ETF | Special Purpose Acquisition Company Risk  
Prospectus [Line Items]  
Risk [Text Block]
Special Purpose Acquisition Company Risk. The Fund may invest in stock, rights, warrants, and other securities of special purpose acquisition companies or similar special purpose entities (collectively, “SPACs’). SPACs are often subject to extreme price volatility and speculative trading. SPACs may have little to no liquidity, and may trade at a discounted NAV. SPACs are “blank check” companies with no operating history. Accordingly, there is a limited basis, if any, on which to evaluate the SPAC’s ability to achieve its business objective, and the value of its securities is particularly dependent on the ability of the entity’s management to complete a profitable acquisition. The value of a SPAC’s securities can by highly volatile and may depreciate over time. A SPAC will not generate any revenues until, at the earliest, after the consummation of a transaction. Among other conflicts of interest, an investment in a SPAC may include the potential for misalignment of incentives in the structure of the SPAC.
F/m Emerald Special Situations ETF | Special Situations Risk  
Prospectus [Line Items]  
Risk [Text Block]
Special Situations Risk. The Fund will seek to benefit from Special Situations, such as mergers, reorganizations, or other unusual events expected to affect a particular issuer. There is a risk that the Special Situation might not occur or involve longer time frames than originally expected, which could have a negative impact on the price of the issuer’s securities and fail to produce gains or produce a loss for the Fund.
F/m Emerald Special Situations ETF | Turnover Rate Risk  
Prospectus [Line Items]  
Risk [Text Block]
Turnover Rate Risk. The Fund may have portfolio turnover rates in excess of 100%. Increased portfolio turnover causes the Fund to incur higher brokerage costs, which may adversely affect the Fund’s performance and may produce increased taxable distributions. The Fund’s portfolio turnover rate is expected to vary from year to year.
F/m Emerald Special Situations ETF | Warrants and Rights Risk  
Prospectus [Line Items]  
Risk [Text Block]
Warrants and Rights Risk. Rights are similar to warrants but normally have a short duration and are distributed directly by the issuer to its shareholders. Warrants and rights are not dividend-paying investments and do not have the voting rights of common stock. They also do not represent any rights in the assets of the issuer. As a result, warrants and rights may be considered more speculative than direct equity investments.
