Apr. 30, 2026
Active Management Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Active Management Risk—The Fund is actively managed with discretion and may underperform market indexes or other mutual funds with similar investment objectives. The Fund’s performance depends heavily on Morningstar’s skill and judgment in managing assets directly (through open- and closed-end investment companies, ETFs and individual securities) and allocating assets to subadvisers, and Morningstar and each subadviser’s skill in selecting securities and executing its strategy. The Fund could experience losses if these judgments prove to be incorrect.
Asset Allocation Risk [Member]

Risk [Text Block]
Asset Allocation Risk—In an attempt to invest in areas that look most attractive based on market, economic or other conditions, the Fund may favor asset classes or market segments that cause the Fund to underperform its benchmark.
Market Risks [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Market Risk—The value of stocks and other securities can be highly volatile and prices may fluctuate widely, which means you should expect a wide range of returns and could lose money, even over a long time period. Various economic, industry, regulatory, political or other factors (such as natural disasters, epidemics and pandemics, war, terrorism, changes in trade regulation or economic sanctions, conflicts, social unrest, recessions, or the threat or occurrence of a government shutdown) may disrupt U.S. and world economies and can dramatically affect markets generally, certain industry sectors, and/or individual companies.
Smaller Companies Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Smaller Companies Risk—The stocks of small- or mid‑sized 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 their securities may trade less frequently and in lower volume than the securities of larger companies, which could lead to higher transaction costs.
Sector Focus Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Sector Focus Risk—The Fund may from time to time have a significant amount of its assets invested in one market sector or group of related industries. To the extent that the Fund focuses on particular sectors, groups of industries or types of investment from time to time, the Fund may be subject to greater risks of adverse developments in such areas of focus than a fund that invests in a wider variety of industries, sectors or investments. Information about the Fund’s investment in a particular industry or market sector is available in its annual and semi-annual reports to shareholders, on the Fund’s website and/or on the Fund’s Forms N‑PORT and N‑CSR.
Technology Sector Risk. Factors that may significantly affect the market value of securities of issuers in the technology sector (which includes semiconductor companies) include the failure to obtain, or delays in obtaining, financing or regulatory approval, intense competition, aggressive pricing, product compatibility, changing consumer preferences, increased government scrutiny, high required corporate capital expenditure for research and development or infrastructure and development of new products, rapid obsolescence and competition from alternative technologies. Such issuers are also heavily dependent on patent and other intellectual property rights, and the loss or impairment of these rights may adversely affect an issuer’s profitability. Semiconductor companies, in particular, are subject to competitive pressures, cyclical demand, rapid innovation, fluctuations in the availability and price of components, and significant capital spending requirements, and are particularly sensitive to
wide fluctuations in securities prices, imbalances in supply and demand, inventory cycles, and disruptions in global manufacturing or distribution networks.
Quantitative Models Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Quantitative Models Risk—Morningstar may utilize quantitative models in managing all or a portion of the Fund. Such quantitative models may not perform as expected and may cause the Fund to underperform other investment strategies that do not use quantitative models. Flaws or errors in the quantitative model’s assumptions, design, execution, or data inputs may adversely affect Fund performance. Due to the significant role technology plays in a quantitative model, use of a quantitative model carries the risk of potential issues with the design, coding, implementation, or maintenance of the technology used in the quantitative model. Quantitative models may underperform in certain market environments including in stressed or volatile market conditions. There can be no assurance that the use of quantitative models by Morningstar will enable the Fund to achieve its objective.
Foreign Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Foreign Securities Risk—Securities of non‑U.S. issuers may be less liquid, more volatile, and harder to value than U.S. securities. They may also be subject to political, economic, and regulatory risks, and market instability. Non‑U.S. issuers also may not be subject to uniform accounting, auditing and financial reporting standards and there may be less reliable and publicly available financial and other information about such issuers, as compared to U.S. issuers.
Currency Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Currency Risk—Because this Fund may invest in securities of non‑U.S. issuers, changes in currency exchange rates (including in the markets in which such non‑U.S. issuers’ securities are traded) could hurt performance. Morningstar or a subadviser may decide not to hedge, or may not be successful in hedging, its currency exposure.
Derivatives Risks [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Derivatives Risk—A derivative is an instrument with a value based on the performance of an underlying currency, security, index, or other reference asset. Derivatives involve risks different from, or possibly greater than, the risks of investing in more traditional investments. Derivatives involve costs, may create leverage, and may be illiquid, volatile, or difficult to value. In addition, derivatives could cause losses if the counterparty to the transaction does not perform as promised. The investment results achieved by using derivatives may not match or fully offset changes in the value of the underlying currency, security, index, or other reference asset that the Fund was attempting to hedge or the investment opportunity it was trying to pursue. Derivatives also are susceptible to operational risks, such as system failures and inadequate controls, and legal risks, such as insufficient documentation and lack of enforceability of a contract.
ETF Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Investment Company/ETF Risk—An investment company, including an open- or closed-end mutual fund or ETF, in which the Fund invests may not achieve its investment objective or execute its investment strategies effectively, or a large purchase or redemption activity by shareholders might negatively affect the value of the shares. The Fund must also pay its pro rata portion of an investment company’s fees and expenses. Shares of ETFs trade on exchanges and may be bought and sold at market value. ETF shares may be thinly traded, making it difficult for the Fund to sell shares at a particular time or an anticipated price. ETF shares may also trade at a premium or discount to the net asset value of the ETF; at times, this premium or discount could be significant.
Valuation risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Valuation riskThe amount the Fund actually receives when selling (or otherwise disposing of) an investment may differ from the Fund’s recorded valuation of that investment. This discrepancy is more likely for investments that trade infrequently, are valued using fair-value methods or third-party pricing vendors, or are held during periods of market stress or heightened volatility. Consequently, the Fund may realize a larger loss or a smaller gain than anticipated based on its stated valuation. Additionally, the Fund’s valuation process could be disrupted by technology failures or errors originating from pricing vendors or other external service providers.
Cybersecurity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Cybersecurity Risk—The Fund, like all companies, may be susceptible to operational and information security risks. Cybersecurity failures or breaches of the Fund or its service providers or the issuers of securities in which a Fund invests, have the ability to cause disruptions and impact business operations, and the Fund and its shareholders could be negatively impacted as a result.
Multimanager and Subadviser Selection Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
Multimanager and Subadviser Selection Risk—To a significant extent, the Fund’s performance depends on Morningstar’s skill in selecting subadvisers and each subadviser’s skill in selecting securities and executing its strategy. Subadviser strategies may occasionally be out of favor and subadvisers may underperform relative to their peers or benchmarks.
