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 69% 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 at least 80% of its net assets (plus borrowings for investment purposes) in common and preferred stocks of U.S. real estate investment trusts and real estate companies. The Portfolio will provide shareholders with at least 60 days' prior notice of any change in this investment policy. For this Portfolio, the sub-adviser (“Sub-Adviser”) defines a real estate company as a company that: (i) derives at least 50% of its total revenue or earnings from owning, operating, leasing, developing, managing, brokering and/or selling real estate; or (ii) has at least 50% of its assets invested in real estate. Companies principally engaged in the real estate industry may include real estate investment trusts, master limited partnerships, real estate owners, real estate managers, real estate brokers, real estate dealers, and companies with substantial real estate holdings. The Sub-Adviser may invest in companies of any market capitalization. However, the Sub-Adviser will generally not invest in companies with market capitalizations of less than $100 million at the time of purchase. The Portfolio also may invest in convertible securities, initial public offerings, and Rule 144A securities. 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 focuses on investments that generally provide income and also have the potential for long-term capital appreciation. The Sub-Adviser uses systematic, top-down research to evaluate property market conditions and trends to judge which market sectors offer potentially attractive returns. The Sub-Adviser uses proprietary analytical techniques to conduct fundamental company analysis, which provides a framework for security selection. This approach incorporates several quantitative and qualitative factors that aid in evaluating performance characteristics of individual securities independently and relative to each other. The Sub-Adviser will also typically employ third-party portfolio optimization tools to help in its evaluation of the Portfolio’s current portfolio and its identification of potential investments for the Portfolio. 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.
Strategy Portfolio Concentration [Text]	rr_StrategyPortfolioConcentration	Under normal market conditions, the Portfolio invests at least 80% of its net assets (plus borrowings for investment purposes) in common and preferred stocks of U.S. real estate investment trusts and real estate companies.
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. Concentration: As a result of the Portfolio “concentrating,” as that term is defined in the 1940 Act, its assets in securities related to a particular industry or group of industries, the Portfolio may be subject to greater market fluctuations than a fund that is more broadly invested across industries. Financial, economic, business, and other developments affecting issuers in a particular industry or group of industries will have a greater effect on the Portfolio, and if securities of the particular industry or group of industries as a group fall out of favor, the Portfolio could underperform, or its net asset value may be more volatile than, funds that have greater industry diversification. Convertible Securities: Convertible securities are securities that are convertible into or exercisable for common stocks at a stated price or rate. Convertible securities are subject to the usual risks associated with debt instruments, such as interest rate and credit risk. In addition, because convertible securities react to changes in the value of the stocks into which they convert, they are subject to market risk. Credit: The price of a bond or other debt instrument is likely to fall if the issuer’s actual or perceived financial health deteriorates, whether because of broad economic or issuer-specific reasons. In certain cases, the issuer could be late in paying interest or principal, or could fail to pay its financial obligations altogether. Initial Public Offerings: Investments in initial public offerings (“IPOs”) and companies that have recently gone public have the potential to produce substantial gains for the Portfolio. However, there is no assurance that the Portfolio will have access to profitable IPOs or that the IPOs in which the Portfolio invests will rise in value. Furthermore, the value of securities of newly public companies may decline in value shortly after the IPO. When the Portfolio’s asset base is small, the impact of such investments on the Portfolio’s return will be magnified. If the Portfolio’s assets grow, it is likely that the effect of the Portfolio’s investment in IPOs on the Portfolio’s return will decline. Interest Rate: With bonds and other fixed rate debt instruments, a rise in market interest rates generally causes values to fall; conversely, values generally rise as market interest rates fall. The higher the credit quality of the instrument, and the longer its maturity or duration, the more sensitive it is likely to be to interest rate risk. In the case of inverse securities, the interest rate paid by the securities is a floating rate, which generally will decrease when the market rate of interest to which the inverse security is indexed increases and will increase when the market rate of interest to which the inverse security is indexed decreases. As of the date of this Prospectus, the United States experiences a low interest rate environment, which may increase the Portfolio’s exposure to risks associated with rising market interest rates. Rising market interest rates could have unpredictable effects on the markets and may expose fixed-income and related markets to heightened volatility. To the extent that the Portfolio invests in fixed-income securities, an increase in market interest rates may lead to increased redemptions and increased portfolio turnover, which could reduce liquidity for certain investments, adversely affect values, and increase costs. Increased redemptions may cause the Portfolio to liquidate portfolio positions when it may not be advantageous to do so and may lower returns. If dealer capacity in fixed-income markets is insufficient for market conditions, it may further inhibit liquidity and increase volatility in the fixed-income markets. Further, recent and potential future changes in government policy may affect interest rates. Investment Model: A manager’s proprietary model may not adequately allow for existing or unforeseen market factors or the interplay between such factors. Portfolios that are actively managed, in whole or in part, according to a quantitative investment model can perform differently from the market as a whole 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 Portfolio. 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. 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. 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.
