Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock
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 the 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 37% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Fund is non-diversified and invests primarily in common stocks of growth-oriented, U.S. companies that the Adviser believes have capital appreciation potential and may grow faster than the U.S. economy. Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in securities issued by large-capitalization companies, which the Adviser defines as companies having a market capitalization, at the time of purchase, within the range of the market capitalization of companies constituting the Russell 1000® Growth Index. As of December 31, 2023, the capitalization range of the Russell 1000® Growth Index was between approximately $978 million and $3 trillion. This investment policy can be changed by the Fund upon 60 days’ prior written notice to shareholders. While the market capitalization range for the Russell 1000® Growth Index will change on a periodic basis, the Fund will normally invest in common stocks of companies with market capitalizations of at least $3 billion at the time of purchase. The Fund tends to hold a relatively focused portfolio of between 25 and 35 companies, although from time to time the Fund may hold fewer or more companies depending on the Adviser’s assessment of the investment opportunities available. From time to time, the Fund may focus its investments in securities of companies in the same economic sector, including the Information Technology sector.
Using a bottom-up approach in selecting securities for the Fund, the Adviser seeks to select securities of companies that it believes are beneficiaries of fundamental change, have strong competitive positions, attractive unit economics capable of generating strong and consistent cash flows as the business scales, shareholder-aligned management teams and the opportunity to generate consistent, long-term growth of intrinsic value. The Adviser typically considers a company’s operational efficiency and management’s plans for capital allocation. Through the Adviser’s investment research process, it seeks to identify the companies that it believes will exceed the market’s expectations for: 1) key financial metrics and 2) sustainable competitive advantage. The Adviser purchases these securities for the Fund when it believes the market has not already reflected these expectations in the current stock price. Additionally, the Adviser typically invests for a 3-5 year time horizon, allowing it to take advantage of discrepancies between short-term price movements and long-term fundamental prospects.
The Fund may invest up to 20% of its net assets in securities of foreign issuers, which may include global depositary receipts (“GDRs”) and, without limitation, sponsored and unsponsored American depositary receipts (“ADRs”) that are actively traded in the United States, including issuers located or operating in emerging markets and frontier markets. The Fund determines that a market is an emerging market if it is included in the MSCI Emerging Markets Index; the Fund determines that a market is a frontier market if it is included in the MSCI Frontier Markets Index. To the extent the Fund invests in securities denominated in a particular currency, it may invest in forward foreign currency exchange contracts to hedge currency risks associated with the investment.
In addition, the Fund may invest in real estate investment trusts (“REITs”). REITs are corporations or trusts that invest primarily in fee or leasehold ownership of real estate, mortgages or shares issued by other REITs, and that receive favorable tax treatment provided they meet certain conditions, including the requirement that they distribute at least 90% of their taxable income.
Holdings are typically sold to make room in the portfolio for more attractive stocks, or where the holding reaches the Adviser’s estimate for its intrinsic value, or in response to an unexpected, negative fundamental change, including a change in management’s strategic direction.

Performance Narrative [Text Block] rr_PerformanceNarrativeTextBlock
The accompanying bar chart and table provide some indication of the risks of investing in the Fund by showing how the Fund’s total returns have varied for the annual periods through December 31, 2023.

The Fund acquired the assets and assumed the liabilities of the Delaware U.S. Growth Fund, a series of Delaware Group Adviser Funds (the “Predecessor Fund”), effective at the close of business on April 16, 2021 (the “Reorganization”), and the Predecessor Fund is the accounting and performance history survivor of the Reorganization. The performance information shown below for the Fund’s Investor Class Shares represent the performance of the Predecessor Fund’s Class A shares, performance for the Fund’s Institutional Class Shares represent the performance of the Predecessor Fund’s Institutional Class shares, and performance for the Fund’s IS Class Shares represent the performance of the Predecessor Fund’s Class R6 shares. The Fund’s performance has not been restated to reflect any differences in expenses paid by the Predecessor Fund and those paid by the Fund. The Adviser of the Fund served as the sole sub-adviser to the Predecessor Fund.

Following the bar chart are the Fund’s highest and lowest quarterly returns during the period shown in the bar chart. The performance table that follows shows how the Fund’s average annual returns over time compare with a broad-based securities market index. The returns reflect any expense limitation arrangements in effect during these periods, without which, the returns would be lower. Past performance (before and after taxes) will not necessarily continue in the future. Updated performance information is available on the Fund’s website at https://jspartners.com/funds/ or by calling 844-577-3863.

During the quarter ended September 30, 2023, the Large-Cap Growth Fund received proceeds from a class action settlement from a company it no longer owns. This settlement had a material impact on the Fund’s performance. On the day the proceeds were received, the IS Class, Institutional Class, and Investor Class had their net asset value positively impacted by 5.81%, 5.79%, and 5.84% respectively.

Jackson Square Large-Cap Growth Fund | Risk Nondiversified Status [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Non-Diversified Fund Risk. Because the Fund is “non-diversified” and may invest a greater percentage of its assets in the securities of a single issuer, a decline in the value of an investment in a single issuer could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio.
Jackson Square Large-Cap Growth Fund | Risk Lose Money [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock In addition to not achieving your investment goals, you could lose all or a portion of your investment in the Fund over short or even long periods of time.
Jackson Square Large-Cap Growth Fund | Risk Not Insured Depository Institution [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock 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 governmental agency.
Jackson Square Large-Cap Growth Fund | General Market Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock General Market Risk. The Fund’s net asset value and investment return will fluctuate based upon changes in the value of its portfolio securities. 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.
Jackson Square Large-Cap Growth Fund | Management Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Management Risk. The Fund may not meet its investment objective or may underperform the market or other mutual funds with similar investment strategies if the Adviser cannot successfully implement the Fund’s investment strategies.
Jackson Square Large-Cap Growth Fund | Equity Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Equity Securities Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific industries, sectors, geographic markets or companies in which the Fund invests.
Jackson Square Large-Cap Growth Fund | Large-Cap Companies Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Large-Cap Companies Risk. The Fund’s investment in larger companies is subject to the risk that larger companies are sometimes unable to attain the high growth rates of successful, smaller companies, especially during extended periods of economic expansion.
Jackson Square Large-Cap Growth Fund | REIT Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
REIT Risk. The real estate industry has been subject to substantial fluctuations and declines on a local, regional and national basis in the past and may continue to be in the future. Also, the value of a REIT can be hurt by economic downturns or by changes in real estate values, rents, property taxes, interest rates, tax treatment, regulations, or the legal structure of a real estate investment trust.
Jackson Square Large-Cap Growth Fund | Foreign Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Foreign Securities Risk. Investments in securities of foreign issuers involve risks not ordinarily associated with investments in securities and instruments of U.S. issuers, including risks relating to political, social and economic developments abroad, differences between U.S. and foreign regulatory and accounting requirements, tax risks, and market practices, as well as fluctuations in foreign currencies. There may be less information publicly available about foreign companies than about a U.S. company, and many foreign companies are not subject to accounting, auditing, and financial reporting standards, regulatory framework and practices comparable to those in the U.S.
Jackson Square Large-Cap Growth Fund | Emerging Markets Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Emerging Markets Risk. Emerging markets are markets of countries in the initial stages of industrialization and that generally have low per capita income.  In addition to the risks of foreign securities in general, emerging markets are generally more volatile, have relatively unstable governments, social and legal systems that do not protect shareholders, economies based on only a few industries and securities markets that are substantially smaller, less liquid and more volatile with less government oversight than more developed countries.
Jackson Square Large-Cap Growth Fund | Frontier Market Countries Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Frontier Market Countries Risk. Frontier market countries generally have smaller economies and even less developed capital markets than traditional emerging markets, and, as a result, the risks of investing in emerging market countries are magnified in frontier market countries. The magnification of risks are the result of: potential for extreme price volatility and illiquidity in frontier markets; government ownership or control of parts of the private sector and of certain companies; trade barriers, exchange controls, managed adjustments in relative currency values and other protectionist measures imposed or
negotiated by the countries with which frontier market countries trade; and the relatively new and unsettled securities laws in many frontier market countries.
Jackson Square Large-Cap Growth Fund | Currency And Foreign Exchange Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Currency and Foreign Exchange Risk. When the Fund buys or sells securities on a foreign stock exchange, the transaction is undertaken in the local currency rather than in U.S. dollars. The value of the foreign currency may increase or decrease against the value of the U.S. dollar, which may impact the value of the Fund’s portfolio holdings and your investment. Other countries may adopt economic policies and/or currency exchange controls that affect their currency valuations in a manner that is disadvantageous to U.S. investors and companies. Such practices may restrict or prohibit the Fund’s ability to repatriate both investment capital and income, or may impose fees for doing so, which could place the Fund’s assets at risk of total loss. Currency risks may be greater in emerging market and frontier market countries than in developed market countries.
Jackson Square Large-Cap Growth Fund | Forward Foreign Currency Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Forward Foreign Currency Risk. The use of forward foreign currency exchange contracts may substantially change the Fund’s exposure to currency exchange rates and could result in losses to the Fund if currencies do not perform as the Adviser expects. The use of these investments as a hedging technique to reduce the Fund’s exposure to currency risks may also reduce its ability to benefit from favorable changes in currency exchange rates.
Jackson Square Large-Cap Growth Fund | Depositary Receipts Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Depositary Receipts Risk.  Depositary receipts are generally subject to the same risks as the foreign securities they represent because their values depend on the performance of the underlying foreign securities.  The Fund may invest in unsponsored depositary receipts that are issued without an agreement with the company that issues the underlying foreign securities. Holders of unsponsored depositary receipts generally bear all the costs of such depositary receipts, and the issuers of unsponsored depositary receipts frequently are under no obligation to distribute shareholder communications received from the company that issues the underlying foreign securities or to pass through voting rights to the holders of the depositary receipts.  Accordingly, available information concerning the issuer may not be current and the prices of unsponsored depositary receipts may be more volatile than the prices of sponsored depositary receipts.
Jackson Square Large-Cap Growth Fund | Liquidity Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Liquidity Risk. From time to time, the trading market for a particular security or type of security in which the Fund invests may become less liquid or even illiquid. Reduced liquidity will have an adverse impact on the Fund’s ability to sell such securities when necessary to meet the Fund’s liquidity needs or in response to a specific economic event and will also generally lower the value of a security. Market prices for such securities may be volatile.
Jackson Square Large-Cap Growth Fund | Growth-Style Investing Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Growth-Style Investing Risk. Investors expect growth companies to increase their earnings at a certain rate that is generally higher than the rate expected for non-growth companies. If a growth company does not meet these expectations, the price of its stock may decline significantly, even if it has increased earnings. Growth companies also typically do not pay dividends. Companies that pay dividends may experience less significant stock price declines during market downturns.
Jackson Square Large-Cap Growth Fund | Investment Focus Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Investment Focus Risk. The Fund may focus its investments, or have a relatively high concentration of assets in a small number of issuers and/or industry subcategories, which may reduce its diversification and result in increased volatility.
Jackson Square Large-Cap Growth Fund | Sector Emphasis Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Sector Emphasis Risk. The securities of companies in the same or related businesses, if comprising a significant portion of the Fund’s portfolio, may in some circumstances react negatively to market conditions, interest rates and economic, regulatory or financial developments and adversely affect the
value of the portfolio to a greater extent than if such securities comprised a lesser portion of the Fund’s portfolio or the Fund’s portfolio was diversified across a greater number of industry sectors. Some industry sectors have particular risks that may not affect other sectors.
Jackson Square Large-Cap Growth Fund | Technology Sector Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Technology Sector Risk: Technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Technology companies may have limited product lines, markets, financial resources or personnel.

Fees waived and expenses paid by the Adviser may be recouped by the Adviser for a period of 36 months following the month during which such fee waiver and expense payment was made, if such recoupment can be achieved without exceeding the expense limit in effect at the time the fee waiver and/or expense payment occurred and the expense limit in place at the time of recoupment. Expenses that were waived prior to April 16, 2021, may not be recouped. The Operating Expenses Limitation Agreement is indefinite but cannot be terminated through at least February 28, 2025.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Fund is non-diversified and invests primarily in common stocks of growth-oriented companies that the Adviser believes have long-term capital appreciation potential and may grow faster than the U.S. economy. Under normal circumstances, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in securities issued by small-and mid-capitalization companies. This investment policy can be changed by the Fund upon 60 days’ prior written notice to shareholders. The Adviser defines small-and mid-capitalization companies as companies, at the time of purchase, within the range of the capitalization of companies constituting the Russell 2500® Growth Index. As of December 31, 2023, the capitalization range of the Russell 2500® Growth Index was between approximately $24 million and $21 billion. The Fund tends to hold a relatively focused portfolio of between 25 and 35 companies, although from time to time the Fund may hold fewer or more stocks depending on the Adviser’s assessment of the investment opportunities available. From time to time, the Fund may focus its investments in securities of companies in the same economic sector, including the Information Technology sector.
The Fund may invest up to 20% of its net assets in securities of foreign issuers, which may include global depositary receipts (“GDRs”) and, without limitation, sponsored and unsponsored American depositary receipts (“ADRs”) that are actively traded in the United States, including issuers located or operating in emerging markets and frontier markets. The Fund determines that a market is an emerging market if it is included in the MSCI Emerging Markets Index; the Fund determines that a market is a frontier market if it is included in the MSCI Frontier Markets Index. To the extent the Fund invests in securities denominated in a particular currency, it may invest in forward foreign currency exchange contracts to hedge currency risks associated with the investment.
In addition, the Fund may invest in real estate investment trusts (“REITs”). REITs are corporations or trusts that invest primarily in fee or leasehold ownership of real estate, mortgages or shares issued by other REITs, and that receive favorable tax treatment provided they meet certain conditions, including the requirement that they distribute at least 90% of their taxable income.
Using a bottom-up approach in selecting securities for the Fund, the Adviser seeks to select securities of companies that it believes are beneficiaries of fundamental change, have strong competitive positions, attractive unit economics capable of generating strong and consistent cash flows as the business scales, shareholder-aligned management teams and the opportunity to generate consistent, long-term growth of intrinsic value. The Adviser typically considers a company’s operational efficiency and management’s plans for capital allocation. Through the Adviser’s investment research process, it seeks to identify the companies that it believes will exceed the market’s expectations for: 1) key financial metrics and 2) sustainable competitive advantage. The Adviser purchases these securities for the Fund when it believes the market has not already reflected these expectations in the current stock price. Additionally, the Adviser typically invests for a 3-5 year time horizon, allowing it to take advantage of discrepancies between short-term price movements and long-term fundamental prospects.
Holdings are typically sold to make room in the portfolio for more attractive stocks, or where the holding reaches the Adviser’s estimate for its intrinsic value, or in response to an unexpected, negative fundamental change, including a change in management’s strategic direction.

Jackson Square SMID-Cap Growth Fund | Risk Nondiversified Status [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Non-Diversified Fund Risk. Because the Fund is “non-diversified” and may invest a greater percentage of its assets in the securities of a single issuer, a decline in the value of an investment in a single issuer could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio.

Risk [Text Block] rr_RiskTextBlock 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 governmental agency.
Jackson Square SMID-Cap Growth Fund | General Market Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock General Market Risk. The Fund’s net asset value and investment return will fluctuate based upon changes in the value of its portfolio securities. 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.
Jackson Square SMID-Cap Growth Fund | Management Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Management Risk. The Fund may not meet its investment objective or may underperform the market or other mutual funds with similar investment strategies if the Adviser cannot successfully implement the Fund’s investment strategies.
Jackson Square SMID-Cap Growth Fund | Equity Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Equity Securities Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific industries, sectors, geographic markets or companies in which the Fund invests.
Jackson Square SMID-Cap Growth Fund | Small-Cap And Mid-Cap Companies Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Small-Cap and Mid-Cap Companies Risk. The small-cap companies in which the Fund invests may not have the management experience, financial resources, product diversification and competitive strengths of large cap companies. Small-cap company stocks may also be bought and sold less often and in smaller amounts than larger company stocks. Securities of small-cap and mid-cap companies may be more volatile and less liquid than the securities of large-cap companies.
Jackson Square SMID-Cap Growth Fund | REIT Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
REIT Risk. The real estate industry has been subject to substantial fluctuations and declines on a local, regional and national basis in the past, and may continue to be in the future. Also, the value of a REIT can be hurt by economic downturns or by changes in real estate values, rents, property taxes, interest rates, tax treatment, regulations, or the legal structure of a real estate investment trust.
Jackson Square SMID-Cap Growth Fund | Foreign Securities Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Foreign Securities Risk. Investments in securities of foreign issuers involve risks not ordinarily associated with investments in securities and instruments of U.S. issuers, including risks relating to political, social, and economic developments abroad, differences between U.S. and foreign regulatory and accounting requirements, tax risks, and market practices, as well as fluctuations in foreign currencies. There may be less information publicly available about foreign companies than about a U.S. company, and many foreign companies are not subject to accounting, auditing, and financial reporting standards, regulatory framework and practices comparable to those in the U.S.
Jackson Square SMID-Cap Growth Fund | Emerging Markets Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Emerging Markets Risk. Emerging markets are markets of countries in the initial stages of industrialization and that generally have low per capita income.  In addition to the risks of foreign securities in general, emerging markets are generally more volatile, have relatively unstable governments, social, and legal systems that do not protect shareholders, economies based on only a few industries, and securities markets that are substantially smaller, less liquid, and more volatile with less government oversight than more developed countries.
Jackson Square SMID-Cap Growth Fund | Frontier Market Countries Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Frontier Market Countries Risk. Frontier market countries generally have smaller economies and even less developed capital markets than traditional emerging markets, and, as a result, the risks of investing in emerging market countries are magnified in frontier market countries. The magnification of risks are the result of: potential for extreme price volatility and illiquidity in frontier markets; government ownership or control of parts of the private sector and of certain companies; trade barriers, exchange controls, managed adjustments in relative currency values and other protectionist measures imposed or negotiated by the countries with which frontier market countries trade; and the relatively new and unsettled securities laws in many frontier market countries.
Jackson Square SMID-Cap Growth Fund | Currency And Foreign Exchange Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Currency and Foreign Exchange Risk. When the Fund buys or sells securities on a foreign stock exchange, the transaction is undertaken in the local currency rather than in U.S. dollars. The value of the foreign currency may increase or decrease against the value of the U.S. dollar, which may impact the value of the Fund’s portfolio holdings and your investment. Other countries may adopt economic policies and/or currency exchange controls that affect their currency valuations in a manner that is disadvantageous to U.S. investors and companies. Such practices may restrict or prohibit the Fund’s ability to repatriate both investment capital and income, or may impose fees for doing so, which could place the Fund’s assets at risk of total loss. Currency risks may be greater in emerging market and frontier market countries than in developed market countries.
Jackson Square SMID-Cap Growth Fund | Forward Foreign Currency Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Forward Foreign Currency Risk. The use of forward foreign currency exchange contracts may substantially change the Fund’s exposure to currency exchange rates and could result in losses to the Fund if currencies do not perform as the Adviser expects. The use of these investments as a hedging technique to reduce the Fund’s exposure to currency risks may also reduce its ability to benefit from favorable changes in currency exchange rates.
Jackson Square SMID-Cap Growth Fund | Depositary Receipts Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Depositary Receipts Risk.  Depositary receipts are generally subject to the same risks as the foreign securities they represent because their values depend on the performance of the underlying foreign securities.  The Fund may invest in unsponsored depositary receipts that are issued without an agreement with the company that issues the underlying foreign securities. Holders of unsponsored depositary receipts generally bear all the costs of such depositary receipts, and the issuers of unsponsored depositary receipts frequently are under no obligation to distribute shareholder communications received from the company that issues the underlying foreign securities or to pass through voting rights to the holders of the depositary receipts.  Accordingly, available information concerning the issuer may not be current and the prices of unsponsored depositary receipts may be more volatile than the prices of sponsored depositary receipts.
Jackson Square SMID-Cap Growth Fund | Liquidity Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Liquidity Risk. From time to time, the trading market for a particular security or type of security in which the Fund invests may become less liquid or even illiquid. Reduced liquidity may have an adverse impact on the Fund’s ability to sell such securities when necessary to meet the Fund’s liquidity needs or in response to a specific economic event and may also generally lower the value of a security. Market prices for such securities may be volatile.
Jackson Square SMID-Cap Growth Fund | Growth-Style Investing Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Growth-Style Investing Risk. Investors expect growth companies to increase their earnings at a certain rate that is generally higher than the rate expected for non-growth companies. If a growth company does not meet these expectations, the price of its stock may decline significantly, even if it has increased earnings. Growth companies also typically do not pay dividends. Companies that pay dividends may experience less significant stock price declines during market downturns.
Jackson Square SMID-Cap Growth Fund | Investment Focus Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Investment Focus Risk. The Fund may focus its investments, or have a relatively high concentration of assets in a small number of issuers and/or industry subcategories, which may reduce its diversification and result in increased volatility.
Jackson Square SMID-Cap Growth Fund | Sector Emphasis Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Sector Emphasis Risk. The securities of companies in the same or related businesses, if comprising a significant portion of the Fund’s portfolio, may in some circumstances react negatively to market conditions, interest rates and economic, regulatory or financial developments and adversely affect the value of the portfolio to a greater extent than if such securities comprised a lesser portion of the Fund’s portfolio or the Fund’s portfolio was diversified across a greater number of industry sectors. Some industry sectors have particular risks that may not affect other sectors.
Jackson Square SMID-Cap Growth Fund | Technology Sector Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Technology Sector Risk: Technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Technology companies may have limited product lines, markets, financial resources or personnel.
Jackson Square SMID-Cap Growth Fund | Healthcare Sector Risk Member  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock
Healthcare Sector Risk: To the extent the Fund invests a significant portion of its assets in the healthcare sector, the Fund’s performance will be sensitive to changes in and, to a greater extent, depend on the overall condition of the healthcare sector. Companies in the healthcare sector are subject to extensive government regulation and their profitability can be significantly affected by regulatory changes. Other factors impacting the healthcare sector include rising costs of medical products and services, pricing pressure and limited product lines, loss or impairment of intellectual property rights and litigation regarding product or service liability.
