Mar. 31, 2026
Equity Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Equity Securities Risk: The Fund is subject to the risk that stock prices will fall over short or extended periods of time. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments, or as a result of irregular and/or unexpected trading activity among retail investors. The prices of securities issued by these companies may decline in response to such developments, which could result in a decline in the value of the Fund’s shares.
Large-Cap Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Large-Cap Risk: Large-cap companies may be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes, and also may not be able to attain the high growth rate of successful smaller companies, especially during extended periods of economic expansion.
Mid-Cap Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Mid-Cap Risk: Stocks of mid-sized companies may be subject to more abrupt or erratic market movements than stocks of larger, more established companies. Mid-sized companies may have limited product lines or financial resources, and may be dependent upon a particular niche of the market.
Preferred Stock Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Preferred Stock Risk: In the event an issuer is liquidated or declares bankruptcy, the claims of owners of bonds take precedence over the claims of those who own preferred and common stock. If interest rates rise, the fixed dividend on preferred stocks may be less attractive, causing the price of preferred stocks to decline.
Small-Cap Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Small-Cap Risk: Stocks of smaller companies may be subject to more abrupt or erratic market movements than stocks of larger, more established companies. Small companies may have limited product lines or financial resources and may be dependent upon a small or inexperienced management group.
Foreign Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Foreign Securities Risk: Investing in foreign securities poses additional risks since political and economic events unique in a country or region will affect those markets and their issuers, while such events may not necessarily affect the U.S. economy or issuers located in the United States. In addition, investments in foreign securities are generally denominated in foreign currency. As a result, changes in the value of those currencies compared to the U.S. dollar may affect (positively or negatively) the value of the Fund’s investments. There are also risks associated with foreign accounting standards, government regulation, market information, and clearance and settlement procedures. To the extent that the securities held by the Fund trade on foreign exchanges or in foreign markets that may be closed when the U.S. market is open, there are likely to be deviations between the current price of the securities held by the Fund and their last quoted price or the securities’ quote from the closed foreign market. Foreign markets may be less liquid and more volatile than U.S. markets and offer less protection to investors. To the extent a Fund focuses its investments in a single country or only a few countries in a particular geographic region, economic, political, regulatory or other conditions affecting such country or region may have a greater impact on Fund performance relative to a more geographically diversified fund.
Depositary Receipts Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Depositary Receipts Risk: Foreign receipts, which include American Depositary Receipts, Global Depositary Receipts, and European Depositary Receipts, are securities that evidence ownership interests in a security or a pool of securities issued by a foreign issuer. The risks of depositary receipts include many risks associated with investing directly in foreign securities.
Emerging Markets Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Emerging Markets Risk: Emerging markets may be more likely to experience political turmoil or rapid changes in market or economic conditions than more developed countries. In addition, the financial stability of issuers (including governments) in emerging market countries may be more precarious than that of issuers in other countries.
Frontier Markets Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ●Frontier Markets Risk: Frontier markets have similar risks to emerging markets, except that these risks are often magnified in a frontier market due to its smaller and less developed economy. As a result, frontier markets may experience greater changes in market or economic conditions, financial stability, price volatility, currency fluctuations, and other risks inherent in foreign securities.
ESG Investing Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] ESG Investing Risk: The Fund's sub-adviser may consider ESG factors that it deems relevant or additive, along with other material factors and analysis, when selecting investments for the Fund. The Fund’s ESG criteria may cause the Fund to forgo opportunities to buy certain securities, or forgo opportunities to gain exposure to certain industries, sectors, regions and countries. In addition, the Fund may be required to sell a security when it might otherwise be disadvantageous for it to do so.
Economic and Market Events Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Economic and Market Events Risk: Events in the U.S. and global financial markets, including actions taken by the U.S. Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times, and for varying periods of time, result in unusually high market volatility, which could negatively impact the Fund’s performance and cause the Fund to experience illiquidity, shareholder redemptions, or other potentially adverse effects. Reduced liquidity in credit and fixed-income markets could negatively affect issuers worldwide. Financial institutions could suffer losses as interest rates rise or economic conditions deteriorate. In addition, the Fund’s service providers are susceptible to operational and information or cybersecurity risks that could result in losses to a Fund and its shareholders.
Management Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Management Risk: In managing the Fund’s portfolio, the Adviser engages one or more sub-advisers to make investment decisions for a portion of or the entire portfolio. There is a risk that the Adviser may be unable to identify and retain sub-advisers who achieve superior investment returns relative to other similar sub-advisers.
Convertible Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Convertible Securities Risk: Convertible securities are subject to the risks of both debt securities and equity securities. The values of convertible securities tend to decline as interest rates rise and, due to the conversion feature, tend to vary with fluctuations in the market value of the underlying security.
Other Investment Companies Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Other Investment Companies Risk: The Fund’s investments in other investment companies, including ETFs, will be subject to substantially the same risks as those associated with the direct ownership of the securities comprising the portfolios of such investment companies, and the value of the Fund’s investment will fluctuate in response to the performance of such portfolios. In addition, if the Fund acquires shares of other investment companies or ETFs, shareholders of the Fund will bear both their proportionate share of the fees and expenses of the Fund (including management and advisory fees) and, indirectly, the fees expenses of the other investment companies or ETFs.
Cyber Security Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Cybersecurity Risk: Cybersecurity breaches are either intentional or unintentional events that allow an unauthorized party to gain access to Fund assets, customer data, or proprietary information, or cause a Fund or Fund service provider to suffer data corruption or lose operational functionality. A cybersecurity breach could result in the loss or theft of customer data or funds, loss or theft of proprietary information or corporate data, physical damage to a computer or network system, or costs associated with system repairs, any of which could have a substantial impact on the Fund. Such incidents could affect issuers in which a Fund invests, thereby causing the Fund’s investments to lose value. The Fund has established risk management systems reasonably designed to seek to reduce the risks associated with cyber-events. However, there is no guarantee that the Fund will be able to prevent or mitigate the impact of any or all cyber-events.
Risk Lose Money [Member]  
Prospectus [Line Items]  
Risk [Text Block] You could lose money on your investment in the Fund and the Fund could also return less than other investments.
Risk Not Insured Depository Institution [Member]  
Prospectus [Line Items]
