Expense Narrative [Text Block]	rr_ExpenseNarrativeTextBlock	The table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Portfolio. You may pay other fees and expenses such as fees and expenses imposed under your variable annuity contracts or variable life insurance policies (“Variable Contract”) or a qualified pension or retirement plan (“Qualified Plan”), which are not reflected in the tables and examples below. 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.

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 128% 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	<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 Portfolio invests at least 80% of its net assets (plus borrowings for investment purposes) in common stock of smaller, lesser-known U.S. 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 smaller companies as those with market capitalizations that fall within the range of companies in the Russell 2000® Growth Index (“Index”) at the time of purchase. The Russell 2000®Growth Index is an index that measures the performance of small growth companies. The market capitalization of companies within the Russell 2000® Growth Index will change with market conditions. The market capitalization of companies in the Russell 2000® Growth Index as of December 31, 2021, ranged from $31.6 million to $13.9 billion.The Sub-Adviser uses fundamental research in an effort to identify companies with the potential for superior earnings growth and sustainable valuations. The Sub-Adviser’s intensive bottom-up, fundamental research drives stock selection, which the Sub-Adviser believes is key to seeking excess returns.Most of the Portfolio’s assets will be invested in U.S. common stocks that the Sub-Adviser expects will experience long-term, above average earnings growth. The Portfolio may at times invest a significant portion of its assets (greater than 25%) in specific sectors of the economy, such as in the technology and health care sectors, respectively. The Portfolio may also invest up to 20% of its net assets in equity securities of foreign issuers, including issuers located in emerging markets that are American Depositary Receipts (“ADRs”) or traded on a U.S. stock exchange, when consistent with the Portfolio’s investment objective.The Portfolio may 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 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% of its total assets.
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 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.Focused Investing: To the extent that the Portfolio invests a substantial portion of its assets in securities related to a particular industry, sector, market segment, or geographic area, its investments will be sensitive to developments in that industry, sector, market segment, or geographic area. The Portfolio is subject to the risk that changing economic conditions; changing political or regulatory conditions; or natural and other disasters affecting the particular industry, sector, market segment, or geographic area in which the Portfolio focuses its investments could have a significant impact on its investment performance and could ultimately cause the Portfolio to underperform, or its net asset value to be more volatile than, other funds that invest more broadly.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, 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; 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.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 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. Wars, 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 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. In addition, military action by Russia in Ukraine could adversely affect global energy and financial markets and therefore could affect the value of a Portfolio’s investments, including beyond a Portfolio’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 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.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.Small-Capitalization Company: Investments in small-capitalization companies may involve greater risk than is customarily associated with larger, more established companies due to the greater business risks of a limited operating history, small size, limited markets and financial resources, narrow product lines, less management depth and more reliance on key personnel. The securities of smaller companies are subject to liquidity risk as they are often traded over-the-counter and may not be traded in volume typical on a national securities exchange.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.

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 I 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.The Portfolio’s performance prior to February 1, 2022 reflects returns achieved pursuant to different principal investment strategies. If the Portfolio’s current strategies had been in place for the prior periods, the performance information shown would have been different.
