Expense Narrative [Text Block]	rr_ExpenseNarrativeTextBlock	The table describes the fees and expenses that you may pay if you buy and hold shares of the Portfolio. The table and expense example do not reflect fees or expenses that are, or may be, imposed under your variable annuity contracts or variable life insurance policies (“Variable Contract”) or a qualified pension or retirement plan (“Qualified Plan”). If these fees or expenses were included in the table, the Portfolio’s expenses would be higher. For more information on these charges, please refer to the documents governing your Variable Contract or consult your plan administrator. The Management Agreement provides for a “bundled fee” arrangement under which the Adviser provides (in addition to advisory services and administrative services), custodial, transfer agency, portfolio accounting, auditing and ordinary legal services in return for a single management fee.

Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	The Portfolio 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. These costs, which are not reflected in Annual Portfolio Operating Expenses or in the Expense Example, affect the Portfolio's performance. During the most recent fiscal year, the Portfolio's portfolio turnover rate was 16% of the average value of its portfolio.

Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	The Example is intended to help you compare the cost of investing in shares of the Portfolio with the costs of investing in other mutual funds. The Example does not reflect expenses and charges which are, or may be, imposed under your Variable Contract or Qualified Plan. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated. The Example also assumes that your investment had a 5% return each year and that the Portfolio'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:
Strategy [Heading]	rr_StrategyHeading	PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Under normal market conditions, the Portfolio invests primarily in equity securities of issuers located throughout the world that it believes have, among other things, sustainable competitive advantages, capable management and financial strength. The Portfolio may invest in securities of companies of any market capitalization. The sub-adviser (“Sub-Adviser”) emphasizes individual stock selection and seeks to identify undervalued securities of issuers located throughout the world, including both developed and emerging market countries. Under normal market conditions, the Portfolio invests in securities of issuers from a number of different countries, including the United States. The Portfolio’s investment process focuses on the sustainability and direction of a company’s long-term returns on capital. Environmental, social and governance (“ESG”) considerations are a fundamental and integrated part of this process, as the Sub-Adviser believes material weaknesses in any of the ESG areas can potentially threaten the long-term sustainability of a company’s returns on capital. The Portfolio may also invest in derivatives for hedging currency and other risks for potential gains. Such derivatives may include forward foreign currency exchange contracts, futures contracts, options, swaps, and structured notes. The Portfolio is non-diversified, which means that it may invest a significant portion of its assets in a single issuer. The Portfolio may invest in real estate-related securities including real estate investment trusts. The Portfolio may also invest in other investment companies, including exchange-traded funds, to the extent permitted under the Investment Company Act of 1940, as amended, and the rules, regulations, and exemptive orders thereunder (“1940 Act”). The Sub-Adviser seeks to invest in companies that it believes have resilient business franchises, strong cash flows, modest capital requirements, capable managements, and growth potential. Securities are selected on a global basis with a bias towards value. The franchise focus of the Portfolio is based on the Sub-Adviser's belief that the intangible assets underlying a strong business franchise (such as patents, copyrights, brand names, licenses, or distribution methods) are difficult to create or to replicate and that carefully selected franchise companies can yield above-average potential for long-term capital appreciation. The Sub-Adviser relies on its research capabilities, analytical resources, and judgment to identify and monitor franchise businesses meeting its investment criteria. The Sub-Adviser believes that the number of issuers with strong business franchises meeting its criteria may be limited, and accordingly, the Portfolio may concentrate its holdings in a relatively small number of companies and may invest up to 25% of the Portfolio's total assets in a single issuer. The Sub-Adviser generally considers selling a portfolio holding when it determines that the holding no longer satisfies its investment criteria or that replacing the holding with another investment should improve the Portfolio's valuation and/or quality. The 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 Portfolio may lend portfolio securities on a short-term or long-term basis, up to 33 1⁄3% of its total assets.
Risk [Heading]	rr_RiskHeading	PRINCIPAL RISKS
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	You could lose money on an investment in the Portfolio. Any of the following risks, among others, could affect Portfolio performance or cause the Portfolio to lose money or to underperform market averages of other funds. 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 company goods or services, regulatory fines and judgments, or business challenges. If a company declares bankruptcy or becomes insolvent, its stock could become worthless. Currency: To the extent that the Portfolio 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 Portfolio 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 securities, credit risk with respect to the counterparty, risk of loss due to changes in market interest rates and liquidity and volatility risk. The amounts required to purchase certain derivatives may be small relative to the magnitude of exposure assumed by the Portfolio. Therefore, the purchase of certain derivatives may have an economic leveraging effect on the Portfolio and exaggerate any increase or decrease in the net asset value. Derivatives may not perform as expected, so the Portfolio 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 currency, security or other risk 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. In addition, given their complexity, derivatives expose the Portfolio to the risk of improper valuation. Foreign Investments/Developing and Emerging Markets: Investing in foreign (non-U.S.) securities may result in the Portfolio experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies due to: smaller markets; differing reporting, accounting, and auditing standards; nationalization, expropriation, or confiscatory taxation; foreign currency fluctuations, currency blockage, or replacement; potential for default on sovereign debt; or political changes or diplomatic developments, which may include the imposition of economic sanctions or other measures by the United States 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 investment risks may be greater in developing and emerging markets than in developed markets. Growth Investing: Prices of growth stocks are more sensitive to investor perceptions of the issuing company’s growth potential and may fall quickly and significantly if investors suspect that actual growth may be less than expected. There is a risk that funds that invest in growth-oriented stocks may underperform other funds that invest more broadly. Growth stocks tend to be more volatile than value stocks, and may underperform the market as a whole over any given time period. Issuer Non-Diversification: A “non-diversified” investment company is subject to the risks of focusing investments in a small number of issuers, industries or foreign currencies, including being more susceptible to risks associated with a single economic, political or regulatory occurrence than a more diversified portfolio might be. Liquidity: If a security is illiquid, the Portfolio might be unable to sell the security at a time when the Portfolio’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 Portfolio to the risk that the price at which it sells illiquid securities will be less than the price at which they were valued when held by the Portfolio. The prices of illiquid securities may be more volatile than more liquid investments. The risks associated with illiquid securities may be greater in times of financial stress. The Portfolio could lose money if it cannot sell a security at the time and price that would be most beneficial to the Portfolio. Market: Stock prices may be volatile or have reduced liquidity in response to real or perceived impacts of factors including, but not limited to, economic conditions, changes in market interest rates, and political events. Stock markets tend to be cyclical, with periods when stock prices generally rise and periods when stock prices generally decline. Any given stock market segment may remain out of favor with investors for a short or long period of time, and stocks as an asset class may underperform bonds or other asset classes during some periods. Additionally, legislative, regulatory or tax policies or developments in these areas may adversely impact the investment techniques available to a manager, add to costs and impair the ability of the Portfolio 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-sized companies causing a fund that invests in these companies to increase in value more rapidly than a fund that invests in larger 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 larger 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 Portfolio 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 U.S. War, terrorism, global health crises and pandemics, and other geopolitical events have led, and in the future may lead, to increased market volatility and may have adverse short- or long-term effects on U.S. and world economies and markets generally. For example, the recent COVID-19 pandemic has resulted, and may continue to result, in significant market volatility, exchange trading suspensions and closures, declines in global financial markets, higher default rates, 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. Those events as well as other changes in 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 investments of the Portfolio and the Portfolio. Any of these occurrences could disrupt the operations of the Portfolio and of the Portfolio’s service providers. Other Investment Companies: The main risk of investing in other investment companies, including exchange-traded funds (“ETFs”), is the risk that the value of the securities underlying an investment company 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 expenses of the Portfolio. The investment policies of the other investment companies may not be the same as those of the Portfolio; as a result, an investment in the other investment companies may be subject to additional or different risks than those to which the Portfolio is typically subject. Real Estate Companies and Real Estate Investment Trusts (“REITs”): Investing in real estate companies and REITs may subject the Portfolio 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, and operating expenses in addition to terrorist attacks, war, or other acts that destroy real property. Investments in REITs are affected by the management skill and creditworthiness of the REIT. The Portfolio 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 Portfolio will receive cash or U.S. government securities as collateral. Investment risk is the risk that the Portfolio will lose money from the investment of the cash collateral received from the borrower. Borrower default risk is the risk that the Portfolio 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 Portfolio to be more volatile. The use of leverage may increase expenses and increase the impact of the Portfolio’s other risks. Value Investing: Securities that appear to be undervalued may never appreciate to the extent expected. Further, because the prices of value-oriented securities tend to correlate more closely with economic cycles than growth-oriented securities, they generally are more sensitive to changing economic conditions, such as changes in market interest rates, corporate earnings and industrial production. The manager may be wrong in its assessment of a company’s value and the securities the Portfolio holds may not reach their full values. A particular risk of the Portfolio’s value approach is that some holdings may not recover and provide the capital growth anticipated or a security judged to be undervalued may actually be appropriately priced. The market may not favor value-oriented securities and may not favor equities at all. During those periods, the Portfolio’s relative performance may suffer. There is a risk that funds that invest in value-oriented stocks may underperform other funds that invest more broadly. An investment in the Portfolio 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.

Bar Chart and Performance Table [Heading]	rr_BarChartAndPerformanceTableHeading	PERFORMANCE INFORMATION
Performance Narrative [Text Block]	rr_PerformanceNarrativeTextBlock	The following information is intended to help you understand the risks of investing in the Portfolio. The following bar chart shows the changes in the Portfolio's performance from year to year, and the table compares the Portfolio's performance to the performance of a broad-based securities market index/indices for the same period. The Portfolio'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 Portfolio's Class ADV shares. Performance for other share classes would differ to the extent they have differences in their fees and expenses. The Class R6 shares performance shown for the period prior to their inception date is the performance of Class S shares without adjustment for any differences in the expenses between the two classes. If adjusted for such differences, returns would be different. Performance shown in the bar chart and in the Average Annual Total Returns table does not include insurance-related charges imposed under a Variable Contract or expenses related to a Qualified Plan. If these charges or expenses were included, performance would be lower. Thus, you should not compare the Portfolio's performance directly with the performance information of other investment products without taking into account all insurance-related charges and expenses payable under your Variable Contract or Qualified Plan. The Portfolio's past performance is no guarantee of future results.
