| Expense Narrative [Text Block] | oef_ExpenseNarrativeTextBlock | This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below. |

| Expense Example [Heading] | oef_ExpenseExampleHeading | Example | ||||||
| Expense Example Narrative [Text Block] | oef_ExpenseExampleNarrativeTextBlock | This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. The Example reflects the Fund’s contractual fee waiver and/or expense reimbursement only for the term of the contractual fee waiver and/or expense reimbursement. Although your actual costs may be higher or lower, based upon these assumptions your costs would be: |

| Portfolio Turnover [Heading] | oef_PortfolioTurnoverHeading | Portfolio Turnover | ||||||
| Portfolio Turnover [Text Block] | oef_PortfolioTurnoverTextBlock | The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover 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. During the most recent fiscal year, the Predecessor Fund’s portfolio turnover was 0% of the average value of its portfolio. The Fund’s portfolio turnover rate may vary from year to year as well as within a year. |
||||||
| Strategy [Heading] | oef_StrategyHeading | PRINCIPAL INVESTMENT STRATEGIES | ||||||
| Strategy Narrative [Text Block] | oef_StrategyNarrativeTextBlock | The Fund seeks to achieve its investment objective by investing primarily in the equity securities (common stocks, preferred stocks and convertible securities) of U.S. companies. The Fund’s sub-adviser, Bragg Financial Advisors, Inc., invests the Fund’s assets by pursuing a value-oriented strategy without limitation on issuer capitalization. The sub-adviser’s strategy begins with a screening process that seeks to identify companies whose stocks sell at discounted price-to-earnings (P/E) and price-to-cash flow (P/CF) multiples. The sub-adviser favors companies that maintain strong balance sheets and have experienced management. Generally, the sub-adviser attempts to identify situations where stock prices are undervalued by the market. Under normal circumstances, the Fund will invest at least 80% of its net assets (for the purpose of this requirement, net assets include net assets plus any borrowings for investment purposes) in equity securities of value companies. The Fund currently defines a value company as a company that (i) is included in at least one value index (as defined by the Fund’s sub-adviser (the “Value Indices”)), (ii) exhibits one or more valuation metrics (such as price-to-earnings ratio, price-to-book value ratio, price-to-cash flow ratio, price-to-sales ratio, enterprise value-to-EBIT, or enterprise value-to-EBITA, among others) that are lower than the average of an applicable equity market index, or (iii) exhibits characteristics that the sub-adviser determines, based on its proprietary valuation models, indicate the company’s shares are trading at a discount to the company’s intrinsic value. The Fund’s sub-adviser currently defines the Value Indices to include the following indices: S&P 500 Value Index, Russell 3000 Value Index, Morningstar Large Cap Value Index, Morningstar Mid Cap Value Index, Morningstar Small Cap Value Index, and S&P Composite 1500 Value Index. The sub-adviser generally sells securities (i) when it believes they are trading for more than their intrinsic value, (ii) to generate tax losses to offset taxable gains, or (iii) if additional cash is needed to fund redemptions. |

| Bar Chart and Performance Table [Heading] | oef_BarChartAndPerformanceTableHeading | PERFORMANCE | ||||||
| Performance Narrative [Text Block] | oef_PerformanceNarrativeTextBlock | The Fund will acquire the assets and liabilities of the FPA Queens Road Value Fund (the “Predecessor Fund”), a series of Investment Managers Series Trust III, through the reorganization of the Predecessor Fund into the Fund (the “Reorganization”), which is expected to occur in the second quarter of 2027. As a result of the Reorganization, the Fund will be the accounting and performance successor of the Predecessor Fund. The returns presented for the periods prior to July 28, 2023, reflect the performance of the FPA Queens Road Value Fund (the “Value Fund”), which was a series of Bragg Capital Trust and reorganized into the Predecessor Fund on July 28, 2023. As a result of this reorganization, the Predecessor Fund adopted the accounting and performance history of the Value Fund. Performance results shown in the bar chart and the performance table below for periods prior to the Reorganization reflect the performance of the Predecessor Fund and the Value Fund. The bar chart and Average Annual Total Returns table below provide an indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for the 1, 5 and 10 calendar year periods compare with those of the S&P 500 Index, a broad-based market index, and the S&P 500 Value Index, an additional index that provides a measure of the U.S. large cap value equity market. The chart and table reflect the reinvestment of dividends and distributions.

| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||
| Risk [Text Block] | oef_RiskTextBlock | Risks Associated with Investing in Equities. Equity securities, generally common stocks, held by the Fund may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect the securities markets generally, such as adverse changes in economic or political conditions, the general outlook for corporate earnings, interest rates or investor sentiment. Sustained periods of market volatility, either globally or in any jurisdiction in which the Fund invests, may increase the risks associated with an investment in the Fund. Equity securities may also lose value because of factors affecting an entire industry or sector, such as increases in production costs, or factors directly related to a specific company, such as decisions made by its management. Equity securities generally have greater price volatility than debt securities. |

| FPA Queens Road Value ETF | Issuer-Specific Changes [Member] | ||||||||
| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||
| Risk [Text Block] | oef_RiskTextBlock | Issuer-Specific Changes. The value of an individual security can be more volatile than the market as a whole and can perform differently than the value of the market as a whole. The prices of, and income generated by, securities held by the Fund may decline in response to various factors directly related to the issuers of such securities, including reduced demand for an issuer’s goods or services, poor management performance, major litigation, investigations or other controversies related to the issuer, changes in the issuer’s financial condition or credit rating, changes in government regulation affecting the issuer or its competitive environment, and strategic initiatives such as mergers, acquisitions or dispositions and the market response to any such initiatives. An individual security may also be affected by factors related to the industry or sector of the issuer or the securities markets as a whole, and conversely an industry or sector or the securities markets may be affected by a change in financial condition or another event affecting a single issuer. At times, the Fund may invest more significantly in a single issuer, which could increase the Fund’s volatility and the risk of loss arising from the factors described above. |

| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||
| Risk [Text Block] | oef_RiskTextBlock | Small and Medium Cap Securities. The prices of securities of small and medium capitalization companies generally are more volatile, less liquid, and more likely to be adversely affected by poor economic or market conditions than securities of larger companies. Small and medium size companies may have limited product lines, markets or financial resources, and they may be dependent upon a limited management group. |
||||||
| FPA Queens Road Value ETF | Risks Associated with Value Investing [Member] | ||||||||
| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||
| Risk [Text Block] | oef_RiskTextBlock | Risks Associated with Value Investing. Value securities, including those selected by the portfolio manager for the Fund, are subject to the risks that their intrinsic value may never be realized by the market and that their prices may go down. In addition, value style investing may fall out of favor and underperform growth or other styles of investing during given periods. The Fund’s value discipline may result in a portfolio of stocks that differs materially from its illustrative index. |
||||||
| FPA Queens Road Value ETF | Management Risk [Member] | ||||||||
| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||
| Risk [Text Block] | oef_RiskTextBlock | Management Risk. The Fund is subject to management risk as an actively-managed investment portfolio. The sub-adviser’s skill in choosing appropriate investments for the Fund will determine, in part, the Fund’s ability to achieve its investment objective. The portfolio manager will apply investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these will produce the desired results. The portfolio manager’s opinion about the intrinsic worth or creditworthiness of a company or security may be incorrect, the portfolio manager may not make timely purchases or sales of securities for the Fund, the Fund’s investment objective may not be achieved, or the market may continue to undervalue the Fund’s securities. In addition, the Fund may not be able to quickly dispose of certain securities holdings. The frequency of trading within the Fund impacts portfolio turnover rates, which are shown in the financial highlights table. A higher rate of portfolio turnover could produce higher trading costs and taxable distributions, which would detract from the Fund’s performance. Moreover, there can be no assurance that all of the sub-adviser’s personnel will continue to be associated with the sub-adviser for any length of time. The loss of services of one or more key employees of the sub-adviser, including the Fund’s portfolio manager, could have an adverse impact on the Fund’s ability to achieve its investment objective. Certain securities or other instruments in which the Fund seeks to invest may not be available in the quantities desired. In such circumstances, the portfolio manager may determine to purchase other securities or instruments as substitutes. Such substitute securities or instruments may not perform as intended, which could result in losses to the Fund. |

| FPA Queens Road Value ETF | Market Risk [Member] | ||||||||
| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||
| Risk [Text Block] | oef_RiskTextBlock | Market Risk. The market price of a security or instrument may decline, sometimes rapidly or unpredictably, due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic, political, or geo-political conditions throughout the world, changes in the general outlook for corporate earnings, changes in interest or currency rates, or adverse investor sentiment generally. The market value of a security or instrument also may decline because of factors that affect a particular industry or industries, such as tariffs, labor shortages or increased production costs and competitive conditions within an industry. In addition, local, regional or global events such as war, acts of terrorism, international conflicts, trade disputes, supply chain disruptions, cybersecurity events, the spread of infectious illness or other public health issues, natural disasters or climate events, or other events could have a significant impact on a security or instrument. The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. |

| FPA Queens Road Value ETF | ETF Structure Risks [Member] | ||||||||
| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||
| Risk [Text Block] | oef_RiskTextBlock | ETF Structure Risks. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks: • Authorized Participant Concentration Risk. Only an authorized participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that act as authorized participants on an agency basis (i.e., on behalf of other market participants). To the extent that these institutions exit the business or are unable to proceed with creation and/or redemption orders with respect to the Fund and no other authorized participant is able to step forward to create or redeem, shares may trade at a discount to the Fund’s net asset value per share (“NAV”) and possibly face delisting. • Market Maker Risk. If the Fund has lower average daily trading volumes, it may rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund shares. Any trading halt or other problem relating to the trading activity of these market makers could result in a dramatic change in the spread between the Fund’s NAV and the price at which the Fund shares are trading on the Exchange, which could result in a decrease in value of the Fund shares. In addition, decisions by market makers or authorized participants to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the Fund’s NAV and the Fund’s market price. This reduced effectiveness could result in Fund shares trading at a discount to NAV and also in greater than normal intra-day bid-ask spreads for Fund shares. • Fluctuation of NAV Risk. As with all ETFs, shares may be bought and sold in the secondary market at market prices. Although it is expected that the market prices of shares will approximate the Fund’s NAV, there may be times when the market prices of shares are more than the NAV intra-day (premium) or less than the NAV intra-day (discount). Differences in market price and NAV may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for shares will be closely related to, but not identical to, the same forces influencing the prices of the holdings of the Fund trading individually or in the aggregate at any point in time. These differences can be especially pronounced during times of market volatility or stress. During these periods, the demand for Fund shares may decrease considerably and cause the market price of Fund shares to deviate significantly from the Fund’s NAV. • Trading Issues Risk. Although the Fund shares are listed for trading on the Exchange, there can be no assurance that an active trading market for such Fund shares will develop or be maintained. Trading in Fund shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund shares inadvisable. In addition, trading in Fund shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “circuit breaker” rules. Market makers are under no obligation to make a market in the Fund shares, and authorized participants are not obligated to submit purchase or redemption orders for Creation Units (as defined below). There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. Initially, due to the small asset size of the Fund, it may have difficulty maintaining its listings on the Exchange. • Costs of Buying or Selling Shares. Investors buying or selling shares in the secondary market will pay brokerage commissions or other charges imposed by brokers, as determined by that broker. Brokerage commissions are often a fixed amount and may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of shares. In addition, secondary market investors will also incur the cost of the difference between the price at which an investor is willing to buy shares (the “bid” price) and the price at which an investor is willing to sell shares (the “ask” price). This difference in bid and ask prices is often referred to as the “spread” or “bid-ask spread.” The bid-ask spread varies over time for shares based on trading volume and market liquidity, and the spread is generally lower if shares have more trading volume and market liquidity and higher if shares have little trading volume and market liquidity. Further, a relatively small investor base in the Fund, asset swings in the Fund, and/or increased market volatility may cause increased bid-ask spreads. Due to the costs of buying or selling shares, including bid-ask spreads, frequent trading of shares may significantly reduce investment results and an investment in shares may not be advisable for investors who anticipate regularly making small investments. |
||||||
| FPA Queens Road Value ETF | Sector Focus Risk [Member] | ||||||||
| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||
| Risk [Text Block] | oef_RiskTextBlock | Sector Focus Risk. The Fund may invest a larger portion of its assets in one or more sectors than many other funds, and thus will be more susceptible to negative events affecting those sectors. For example, as of May 31, 2026, 26.21% of the Predecessor Fund’s assets were invested in the financial sector, and 25.70% of the Predecessor Fund’s assets were invested in the industrials sector. • Financial Sector Risk. Companies in the financial sector are subject to extensive governmental regulation, which may limit both the amounts and types of loans and other financial commitments they can make, the interest rates and fees they can charge, the scope of their activities, the prices they can charge and the amount of capital they must maintain. Profitability is largely dependent on the availability and cost of capital funds and can fluctuate significantly when interest rates change or due to increased competition. In addition, deterioration of the credit markets generally may cause an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. Certain events in the financial sector may cause an unusually high degree of volatility in the financial markets, both domestic and foreign, and cause certain companies in the financial sector to incur large losses. Securities of companies in the financial sector may experience a dramatic decline in value when such companies experience substantial declines in the valuations of their assets, take action to raise capital (such as the issuance of debt or equity securities), or cease operations. Credit losses resulting from financial difficulties of borrowers and financial losses associated with investment activities can negatively impact the sector. Adverse economic, business or political developments could adversely affect financial institutions engaged in mortgage finance or other lending or investing activities directly or indirectly connected to the value of real estate. • Industrials Sector Risk. Industrial companies are affected by supply and demand both for their specific product or service and for industrial sector products and services in general. Government regulation, world events, exchange rates and economic conditions, technological developments and liabilities for environmental damage and general civil liabilities may likewise affect the performance of these companies. Aerospace and defense companies, a component of the industrial sector, can be significantly affected by government spending policies because companies involved in this industry rely, to a significant extent, on U.S. and foreign government demand for their products and services. Thus, the financial condition of, and investor interest in, aerospace and defense companies are heavily influenced by governmental defense spending policies which are typically under pressure from efforts to control the U.S. (and other) government budgets. Transportation securities, another component of the industrial sector, are cyclical and have occasional sharp price movements which may result from changes in the economy, fuel prices, labor agreements and insurance costs. |
||||||
| FPA Queens Road Value ETF | Recent Market Events [Member] | ||||||||
| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||
| Risk [Text Block] | oef_RiskTextBlock | Recent Market Events. Periods of market volatility may occur in response to market events, public health emergencies, natural disasters or climate events, and other economic, political, and global macro factors. U.S. and international markets have recently experienced, and may continue to experience, periods of significant volatility due to various factors, including uncertainty regarding inflation and central banks’ interest rate changes, the possibility of a national or global recession, trade tensions and tariffs, and political and geopolitical events. In addition, wars or threats of war and aggression, such as Russia’s invasion of Ukraine and conflicts among nations and militant groups in the Middle East, have led, and in the future may lead, to increased short-term market volatility and may have adverse long-term effects on the U.S. and world economies and markets generally, each of which may negatively impact the Fund’s investments. Additionally, since the change in the U.S. presidential administration in 2025, the administration has pursued an aggressive foreign policy agenda, including actual or potential imposition of tariffs, which may have consequences on the United States’ relations with foreign countries, the economy, and markets generally. These and other similar events could be prolonged and could adversely affect the value and liquidity of the Fund’s investments, impair the Fund’s ability to satisfy redemption requests, and negatively impact the Fund’s performance. |
||||||
| FPA Queens Road Value ETF | Cybersecurity Risk [Member] | ||||||||
| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||
| Risk [Text Block] | oef_RiskTextBlock | Cybersecurity Risk. Cybersecurity incidents may allow an unauthorized party to gain access to Fund assets, customer data (including private shareholder information), or proprietary information, or cause the Fund, the Adviser, the sub-adviser and/or other service providers (including custodians, sub-custodians, transfer agents and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality. In an extreme case, a shareholder’s ability to exchange or redeem Fund shares may be affected. The use of artificial intelligence and machine learning could exacerbate these risks. Issuers of securities in which the Fund invests are also subject to cybersecurity risks, and the value of those securities could decline if the issuers experience cybersecurity incidents. |
