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 Annual Fund Operating Expenses or in the Expense Example, affect the Fund's performance.During the most recent fiscal year, the Fund's portfolio turnover rate was 91% of the average value of its portfolio.

Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock This Example is intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example shows costs if you sold (redeemed) your shares at the end of the period or continued to hold them. The Example also assumes that your investment had a 5% return each year and that the Fund's operating expenses remain the same. The Example reflects applicable expense limitation agreements and/or waivers in effect, if any, for the one-year period and the first year of the three-, five-, and ten-year periods. Although your actual costs may be higher or lower, based on these assumptions your costs would be:The Example does not reflect sales charges (loads) on reinvested dividends (and other distributions). If these sales charges (loads) were included, your costs would be higher.
Strategy [Heading] rr_StrategyHeading <span style="color:#000000;font-family:Arial;font-size:11.16pt;font-weight:bold;text-transform:uppercase;">Principal Investment Strategies</span>
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock Under normal market conditions, the Fund invests at least 65% of its total assets in equity securities of companies located in a number of different countries other than the U.S. The Fund may invest in securities of companies from emerging market countries. The Fund may also invest in depositary receipts, warrants, and rights of foreign issuers. The Fund may invest in real estate-related securities including real estate investment trusts (“REITs”).The Fund may use derivatives, including futures, options, swaps, and forward foreign currency exchange contracts, typically for hedging purposes to reduce risk (such as interest rate risk, currency risk, and price risk), as a substitute for the sale or purchase of the underlying securities, and for the purpose of maintaining equity market exposure on its cash balance.The Fund may invest in other investment companies, including exchange-traded funds (“ETFs”), to the extent permitted under the Investment Company Act of 1940, as amended, and the rules and regulations thereunder , and under the terms of applicable no-action relief or exemptive orders granted thereunder .Investment Adviser allocates the Fund’s assets to different sub-advisers. When selecting sub-advisers, the Investment Adviser takes into account a wide variety of factors and considerations, including among other things the investment strategy of a potential sub-adviser, its personnel, and its fit with other sub-advisers to the Fund. Among those, the Investment Adviser will typically consider the extent to which a potential sub-adviser takes into account environmental, social, and governance (“ESG”) factors as part of its investment process. ESG factors will be only one of many considerations in the Investment Adviser’s evaluation of any potential sub-adviser; the extent to which ESG factors will affect the Investment Adviser’s decision to retain a sub-adviser, if at all, will depend on the analysis and judgment of the Investment Adviser.PanAgora Asset Management, Inc. (“PanAgora”) and Voya Investment Management Co. LLC (“Voya IM”) (each, a “Sub-Adviser”and collectively, the “Sub-Advisers”) provide the day-to-day management of the Fund. The Sub-Advisers act independently of each other and use their own methodology for selecting investments. The Investment Adviser will determine the amount of Fund assets allocated to each Sub-Adviser.Each Sub-Adviser may sell securities for a variety of reasons, such as to secure gains, limit losses, or redeploy assets into opportunities believed to be more promising, among others.The Fund may lend portfolio securities on a short-term or long-term basis, up to 33 1∕3% of its total assets.PanAgora Asset Management, Inc.To manage its portion of the Fund’s assets, PanAgora employs a strategy which seeks to achieve the Fund’s investment objective by using a proprietary Dynamic Equity alpha model that integrates a variety of measures, including issuer-specific, sector-specific, and region-specific factors. The strategy seeks to identify and exploit investment opportunities resulting from investors’ under/over reactions to market information and market inefficiencies.PanAgora, using its proprietary Dynamic Equity investment process, constructs a forecasting model for every security in PanAgora’s defined investment universe, contingent on each security’s distinct characteristics. The model uses a broad array of factors that PanAgora believes are predictive of security returns including, but not limited to, value, momentum, and quality factors. The Dynamic Equity model then combines the return forecasts with information from a proprietary risk model to seek to derive PanAgora’s optimal constrained portfolio. PanAgora seeks to buy securities for the Fund with high forecasted returns, based on PanAgora’s proprietary forecasting model. Size limitations are placed on portfolio positions by PanAgora for risk management purposes.Voya Investment Management Co. LLCTo manage its portion of the Fund’s assets, Voya IM employs a “passive management” approach designed to track the performance of a custom index created by FTSE for Voya IM that was based on the FTSE Developed ex US Select Factor Index (the “Index”). The Index is designed to capture explicit exposure to a broad set of five factors contributing to developed equity market performance outside of the United States. These five factors include Momentum, Quality, Size, Value and Volatility. The Index is part of the FTSE Global Factor Index Series, and has been customized to minimize trading costs through a narrowing of index constituents while still maintaining strong factor exposure. As a result of the five factor selection process, the Index may be focused in one or more industries, which may change from time to time. As of December 31, 2022, a portion of the Index was focused in the industrials sector.The Fund’s portfolio may not always hold all of the same securities as the Index. Voya IM may also invest in ETFs, stock index futures and other derivatives as a substitute for the sale or purchase of securities in the Index and to provide equity exposure to the Fund’s cash position. Although Voya IM attempts to track, as closely as possible, the performance of the Index, the Fund’s portfolio does not always perform exactly like the Index. Unlike the Index, the Fund has operating expenses and transaction costs and therefore has a performance disadvantage versus the Index.
Risk [Heading] rr_RiskHeading <span style="color:#000000;font-family:Arial;font-size:11.16pt;font-weight:bold;text-transform:uppercase;">Principal Risks</span>
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock You could lose money on an investment in the Fund. Any of the following risks, among others, could affect Fund performance or cause the Fund to lose money or to underperform market averages of other funds. The principal risks are presented in alphabetical order to facilitate readability, and their order does not imply that the realization of one risk is more likely to occur or have a greater adverse impact than another risk.Company: The price of a company’s stock could decline or underperform for many reasons, including, among others, poor management, financial problems, reduced demand for the company’s goods or services, regulatory fines and judgments, or business challenges. If a company is unable to meet its financial obligations, declares bankruptcy, or becomes insolvent, its stock could become worthless.Currency: To the extent that the Fund invests directly or indirectly in foreign (non-U.S.) currencies or in securities denominated in, or that trade in, foreign (non-U.S.) currencies, it is subject to the risk that those foreign (non-U.S.) currencies will decline in value relative to the U.S. dollar or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency being hedged by the Fund through foreign currency exchange transactions.Derivative Instruments: Derivative instruments are subject to a number of risks, including the risk of changes in the market price of the underlying asset, reference rate, or index credit risk with respect to the counterparty, risk of loss due to changes in market interest rates, liquidity risk, valuation risk, and volatility risk. The amounts required to purchase certain derivatives may be small relative to the magnitude of exposure assumed by the Fund. Therefore, the purchase of certain derivatives may have an economic leveraging effect on the Fund and exaggerate any increase or decrease in the net asset value. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging purposes, the change in value of a derivative may not correlate as expected with the asset, reference rate, or index being hedged. When used as an alternative or substitute for direct cash investment, the return provided by the derivative may not provide the same return as direct cash investment.Environmental, Social, and Governance (Multi-Manager): The Investment Adviser’s consideration of ESG factors in selecting sub-advisers for the Fund is based on information that is not standardized, some of which can be qualitative and subjective by nature. There is no minimum percentage of the Fund’s assets that will be allocated to sub-advisers that consider ESG factors as part of their investment processes, and the Investment Adviser may choose to select sub-advisers that do not consider ESG factors as part of their investment processes. It is possible that the Fund will have less exposure to ESG-focused strategies than other comparable mutual funds. There can be no assurance that a sub-adviser selected by the Investment Adviser, which includes its consideration of ESG factors, will provide more favorable investment performance than another potential sub-adviser, and such a sub-adviser may, in fact, underperform other potential sub-advisers.Focused Investing (Index): To the extent that the Fund’s benchmark or other index is substantially composed of securities in a particular industry, sector, market segment, or geographic area, the Fund may allocate its investments to approximately the same extent as the index as part of its investment strategy. As a result, the Fund may be more sensitive to financial, economic, business, political, regulatory, and other developments and conditions, including natural or other disasters, affecting issuers in a particular industry, sector, market segment, or geographic area in which the Fund focuses its investments, and if securities of such industry, sector, market segment, or geographic area fall out of favor, the Fund could underperform, or be more volatile than, a fund that has greater diversification.•Industrials Sector: Companies involved in the industrials sector include those whose businesses are dominated by one of the following activities: the manufacture and distribution of capital goods, including aerospace and defense, construction, engineering and building products, electrical equipment, and industrial machinery; the provision of commercial services and supplies, including printing, employment, environmental, and office services; and the provision of transportation services, including airlines, couriers, marine, road and rail, and transportation infrastructure. Companies involved in the industrials sector are affected by changes in the supply and demand for products and services, product obsolescence, claims for environmental damage or product liability, and general economic conditions, among other factors.Foreign (Non-U.S.) Investments/Developing and Emerging Markets: Investing in foreign (non-U.S.) securities may result in the Fund experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies due, in part, to: smaller markets; differing reporting, accounting, auditing, and financial reporting standards and practices; nationalization, expropriation, or confiscatory taxation; foreign currency fluctuations, currency blockage, or replacement; potential for default on sovereign debt; and political changes or diplomatic developments, which may include the imposition of economic sanctions or other measures by the U.S. or other governments and supranational organizations. Markets and economies throughout the world are becoming increasingly interconnected, and conditions or events in one market, country, or region may adversely impact investments or issuers in another market, country, or region. Foreign (non-U.S.) investment risks may be greater in developing and emerging markets than in developed markets.Index Strategy (Fund): The index selected may underperform the overall market. To the extent the Fund (or a portion of the Fund) seeks to track an index’s performance, the Fund will not use defensive strategies or attempt to reduce its exposure to poor performing securities in the index. To the extent the Fund’s investments track its target index, such Fund may underperform other funds that invest more broadly. Errors in index data, index computations or the construction of the index in accordance with its methodology may occur from time to time and may not be identified and corrected by the index provider for a period of time or at all, which may have an adverse impact on the Fund. The correlation between the Fund’s performance and index performance may be affected by the Fund’s expenses and the timing of purchases and redemptions of the Fund’s shares. In addition, the Fund’s actual holdings might not match the index and the Fund’s effective exposure to index securities at any given time may not precisely correlate.Investing through Stock Connect: Shares in mainland China-based companies that trade on Chinese stock exchanges such as the Shanghai Stock Exchange and the Shenzhen Stock Exchange (“China A-Shares”) may be purchased directly or indirectly through the Shanghai-Hong Kong Stock Connect (“Stock Connect”), a mutual market access program designed to, among other things, enable foreign investment in the People’s Republic of China (“PRC”) via brokers in Hong Kong. There are significant risks inherent in investing in China A-Shares through Stock Connect. The underdeveloped state of PRC’s investment and banking systems subjects the settlement, clearing, and registration of China A-Shares transactions to heightened risks. Stock Connect can only operate when both PRC and Hong Kong markets are open for trading and when banking services are available in both markets on the corresponding settlement days. As such, if either or both markets are closed on a U.S. trading day, the Fund may not be able to dispose of its China A-Shares in a timely manner, which could adversely affect the Fund’s performance.The Chinese economy is generally considered an emerging and volatile market. Significant portions of the Chinese securities markets may become rapidly illiquid because Chinese issuers have the ability to suspend the trading of their equity securities under certain circumstances, and have shown a willingness to exercise that option in response to market volatility, epidemics, pandemics, adverse economic, market or political events, and other events. In addition, there may be restrictions on investments in Chinese companies. For example, on November 12, 2020, the President of the United States signed an Executive Order prohibiting U.S. persons from purchasing or investing in publicly-traded securities of companies identified by the U.S. government as “Communist Chinese military companies.” The list of such companies can change from time to time, and as a result of forced selling or inability to participate in an investment the Investment Adviser/Sub-Adviser otherwise believes is attractive, the Fund may incur losses.Investment Model: A Sub-Adviser’s proprietary model may not adequately take into account existing or unforeseen market factors or the interplay between such factors. Funds that are actively managed, in whole or in part, according to a quantitative investment model can perform differently from the market, based on the investment model and the factors used in the analysis, the weight placed on each factor, and changes from the factors’ historical trends. Mistakes in the construction and implementation of the investment models (including, for example, data problems and/or software issues) may create errors or limitations that might go undetected or are discovered only after the errors or limitations have negatively impacted performance. There is no guarantee that the use of these investment models will result in effective investment decisions for the Fund.Liquidity: If a security is illiquid, the Fund might be unable to sell the security at a time when the Fund’s manager might wish to sell, or at all. Further, the lack of an established secondary market may make it more difficult to value illiquid securities, exposing the Fund to the risk that the prices at which it sells illiquid securities will be less than the prices at which they were valued when held by the Fund, which could cause the Fund to lose money. The prices of illiquid securities may be more volatile than more liquid securities, and the risks associated with illiquid securities may be greater in times of financial stress.Market: The market values of securities will fluctuate, sometimes sharply and unpredictably, based on overall economic conditions, governmental actions or intervention, market disruptions caused by trade disputes or other factors, political developments, and other factors. Prices of equity securities tend to rise and fall more dramatically than those of fixed-income instruments. Additionally, legislative, regulatory, or tax policies or developments may adversely impact the investment techniques available to a manager, add to costs and impair the ability of the Fund to achieve its investment objectives.Market Capitalization: Stocks fall into three broad market capitalization categories: large, mid, and small. Investing primarily in one category carries the risk that, due to current market conditions, that category may be out of favor with investors. If valuations of large-capitalization companies appear to be greatly out of proportion to the valuations of mid- or small-capitalization companies, investors may migrate to the stocks of mid- and small-capitalization companies causing a fund that invests in these companies to increase in value more rapidly than a fund that invests in large-capitalization companies. Investing in mid- and small-capitalization companies may be subject to special risks associated with narrower product lines, more limited financial resources, smaller management groups, more limited publicly available information, and a more limited trading market for their stocks as compared with large-capitalization companies. As a result, stocks of mid- and small-capitalization companies may be more volatile and may decline significantly in market downturns.Market Disruption and Geopolitical: The Fund is subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets. Due to the increasing interdependence among global economies and markets, conditions in one country, market, or region might adversely impact markets, issuers and/or foreign exchange rates in other countries, including the United States. Wars, terrorism, global health crises and pandemics, and other geopolitical events that have led, and may continue to lead, to increased market volatility and may have adverse short- or long-term effects on U.S., and global economies and markets, generally. For example, the COVID-19 pandemic has resulted, and may continue to result, in significant market volatility, exchange suspensions and closures, declines in global financial markets, higher default rates, supply chain disruptions, and a substantial economic downturn in economies throughout the world. Natural and environmental disasters and systemic market dislocations are also highly disruptive to economies and markets. In addition, military action by Russia in Ukraine has, and may continue to, adversely affect global energy and financial markets and therefore could affect the value of the Fund’s investments, including beyond the Fund’s direct exposure to Russian issuers or nearby geographic regions. The extent and duration of the military action, sanctions, and resulting market disruptions are impossible to predict and could be substantial. Those events as well as other changes in foreign (non-U.S.) and domestic economic, social, and political conditions also could adversely affect individual issuers or related groups of issuers, securities markets, interest rates, credit ratings, inflation, investor sentiment, and other factors affecting the value of the Fund’s investments. Any of these occurrences could disrupt the operations of the Fund and of the Fund’s service providers.Other Investment Companies: The main risk of investing in other investment companies, including ETFs, is the risk that the value of an investment company’s underlying investments might decrease. Shares of investment companies that are listed on an exchange may trade at a discount or premium from their net asset value. You will pay a proportionate share of the expenses of those other investment companies (including management fees, administration fees, and custodial fees) in addition to the Fund’s expenses. The investment policies of the other investment companies may not be the same as those of the Fund; as a result, an investment in the other investment companies may be subject to additional or different risks than those to which the Fund is typically subject. In addition, shares of ETFs may trade at a premium or discount to net asset value and are subject to secondary market trading risks. Secondary markets may be subject to irregular trading activity, wide bid/ask spreads, and extended trade settlement periods in times of market stress because market makers and authorized participants may step away from making a market in an ETF’s shares, which could cause a material decline in the ETF’s net asset value.Real Estate Companies and Real Estate Investment Trusts: Investing in real estate companies and REITs may subject the Fund to risks similar to those associated with the direct ownership of real estate, including losses from casualty or condemnation, changes in local and general economic conditions, supply and demand, market interest rates, zoning laws, regulatory limitations on rents, property taxes, overbuilding, high foreclosure rates, and operating expenses in addition to terrorist attacks, wars, or other acts that destroy real property. In addition, REITs may also be affected by tax and regulatory requirements in that a REIT may not qualify for favorable tax treatment or regulatory exemptions. Investments in REITs are affected by the management skill of the REIT’s sponsor. The Fund will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests.Securities Lending: Securities lending involves two primary risks: “ investment risk ” and “ borrower default risk. ” When lending securities, the Fund will receive cash or U.S. government securities as collateral. Investment risk is the risk that the Fund will lose money from the investment of the cash collateral received from the borrower. Borrower default risk is the risk that the Fund will lose money due to the failure of a borrower to return a borrowed security. Securities lending may result in leverage. The use of leverage may exaggerate any increase or decrease in the net asset value, causing the Fund to be more volatile. The use of leverage may increase expenses and increase the impact of the Fund’s other risks.An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

Performance Narrative [Text Block] rr_PerformanceNarrativeTextBlock The following information is intended to help you understand the risks of investing in the Fund. The following bar chart shows the changes in the Fund's performance from year to year, and the table compares the Fund's performance to the performance of a broad-based securities market index/indices with investment characteristics similar to those of the Fund for the same period. The Fund's performance information reflects applicable fee waivers and/or expense limitations in effect during the period presented. Absent such fee waivers/expense limitations, if any, performance would have been lower. The bar chart shows the performance of the Fund's Class I shares. Performance for other share classes would differ to the extent they have differences in their fees and expenses.On January 20, 2017, PanAgora and Voya IM were added as sub-advisers and Wellington Management Company LLP (which served as a sub-adviser from date of inception to January 20, 2017) was removed as a sub-adviser. These changes to the sub-advisers resulted in a change to the Fund’s principal investment strategies. On November 22, 2013 Thornburg Investment Management, Inc. (which served as a sub-adviser from date of inception to November 22, 2013) was removed as a sub-adviser. If the Fund’s current sub-advisers and strategies had been in place for the prior period, the performance information shown would have been different.
