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 Examples, affect the Portfolio's performance. During the most recent fiscal year, the Portfolio's portfolio turnover rate was 98% 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 Examples do 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. 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 stock of mid-sized U.S. companies. The Portfolio will provide shareholders with at least 60 days' prior notice of any change in this investment policy. The Portfolio normally invests in companies that the sub-adviser ("Sub-Adviser") believes have above average prospects for growth. For this Portfolio, the Sub-Adviser defines mid-sized companies as those companies with market capitalizations that fall within the range of companies in the Russell Midcap® Growth Index at the time of purchase. Capitalization of companies in the Russell Midcap® Growth Index will change with market conditions. The market capitalization of companies in the Russell Midcap® Growth Index as of September 30, 2015, ranged from $903.4 million to $27.8 billion. The Portfolio may also invest in derivative instruments including futures or index futures that have a similar profile to the benchmark of the Portfolio. The Portfolio typically uses derivatives for the purpose of maintaining equity market exposure on its cash balance. The Portfolio may also invest in foreign securities. 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"). In managing the Portfolio, the Sub-Adviser uses a stock selection process that combines the discipline of quantitative screens with rigorous fundamental security analysis. The quantitative screens focus the fundamental analysis by seeking to identify the stocks of companies with strong business momentum that demonstrate relative price strength, and have a perceived value not reflected in the current price. The objective of the fundamental analysis is to confirm the persistence of the company's revenue and earnings growth and validate the Sub-Adviser's expectations for earnings estimate revisions, particularly relative to consensus. A determination of reasonable valuation for individual securities is based on the judgment of the Sub-Adviser. 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	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 given company's stock could decline or underperform for many reasons including, among others, poor management, financial problems, 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 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. 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 interest rates and liquidity risk. The use of certain derivatives may also have a leveraging effect which may increase the volatility of the Portfolio and reduce its returns. Derivatives may not perform as expected, so the Portfolio may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the currency, security or other risk being hedged. In addition, given their complexity, derivatives expose the Portfolio to the risk of improper valuation. Foreign Investments    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. Investment Model    The 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, changes from the factors' historical trends, and technical issues in the construction and implementation of the investment models (including, for example, data problems and/or software issues). 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, and the security could have the effect of decreasing the overall level of the Portfolio's liquidity. Further, the lack of an established secondary market may make it more difficult to value illiquid securities, which could vary from the amount the Portfolio could realize upon disposition. The Portfolio may make investments that become less liquid in response to market developments or adverse investor perception. 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 and are affected by the real or perceived impacts of such factors as economic conditions 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. From time to time, the stock market may not favor the growth-oriented securities in which the Portfolio invests. Rather, the market could favor value-oriented securities or may not favor equities at all. Additionally, legislative, regulatory or tax policies or developments in these areas may adversely impact the investment techniques available to a manager, add to Portfolio costs and impair the ability of the Portfolio to achieve its investment objectives. Mid-Capitalization Company    Investments in mid-capitalization companies may involve greater risk than is customarily associated with larger, more established companies due to the greater business risks of smaller size, limited markets and financial resources, narrow product lines and the frequent lack of depth of management. Consequently, the securities of smaller companies may have limited market stability and may be subject to more abrupt or erratic market movements than securities of larger, more established growth companies or the market averages in general. Other Investment Companies    The main risk of investing in other investment companies, including exchange-traded funds, 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. In addition, because the Portfolio may invest in other investment companies, 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. Securities Lending    Securities lending involves two primary risks: "investment risk" and "borrower default risk." 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 in a timely manner. 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. Because Class R6 shares of the Portfolio had not commenced operations as of the calendar year ended December 31, 2014, the following bar chart shows the changes in the Portfolio's Class I shares' performance from year to year, and the table compares the Portfolio's Class I shares' performance to the performance of a broad-based securities market index/indices for the same period. Class R6 shares and Class I shares of the Portfolio would have substantially similar performance because they invest in the same portfolio of securities and have similar expenses. 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. Performance 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.
Performance Information Illustrates Variability of Returns [Text]	rr_PerformanceInformationIllustratesVariabilityOfReturns	the following bar chart shows the changes in the Portfolio's Class I shares' performance from year to year, and the table compares the Portfolio's Class I shares' performance to the performance of a broad-based securities market index/indices for the same period.
