Expense Narrative [Text Block]	rr_ExpenseNarrativeTextBlock	The table below shows the fees and expenses that you may pay if you invest in shares of the Portfolio. The table does not include Contract charges. Because Contract charges are not included, the total fees and expenses that you will incur will be higher than the fees and expenses set forth in the table. See your Contract prospectus for more information about Contract charges.

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 example, affect the Portfolio's performance. During the Portfolio's most recent fiscal year ended December 31, the Portfolio's portfolio turnover rate was 62% of the average value of its portfolio.

Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	The following example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The table does not include Contract charges. Because Contract charges are not included, the total fees and expenses that you will incur will be higher than the fees and expenses set forth in the example. See your Contract prospectus for more information about Contract charges.The example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has 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 Narrative [Text Block]	rr_StrategyNarrativeTextBlock	In pursuing its investment objective, the Portfolio normally invests at least 80% of its assets (net assets plus any borrowings made for investment purposes) in common stock of major established companies as well as smaller companies. The Portfolio considers major established companies to be those companies with market capitalizations within the market capitalization range of the Russell 1000® Index (measured at the time of purchase).A bottom-up stock selection process is utilized and the Portfolio invests in securities of growth and value stocks. Each portfolio manager is responsible for selecting the securities within his discipline. The growth portfolio manager believes that growth in earnings and cash flows drives share prices over the long term; that excess returns are generated by investing in market-leading companies that create economic value through long-duration competitive advantages; and that a deeply researched understanding of company and industry fundamentals leads to successful stock selection. The growth portfolio manager looks for companies with unique business models that build sustainable competitive advantages; catalysts that drive growth rates well above that of the market; superior financial characteristics; and attractive long-term valuations. The growth portfolio manager seeks to capture acceleration or duration of growth that is not fully reflected in a stock’s price. The value portfolio manager seeks investments in companies he believes are being valued at a discount to their intrinsic value. A company’s valuation is very important in this determination, as are the durability of a company’s free cash flow and earnings growth. A disciplined process to manage risk in both security selection and portfolio construction is a critical component of the value portfolio manager’s investment process. The Portfolio may invest up to 30% of its total assets in foreign securities (not including American Depositary Receipts and similar instruments). The Portfolio employs a bottom-up stock selection process and invests in growth and value stocks.
Risk [Heading]	rr_RiskHeading	<span style="font-family:Arial;font-size:10pt;font-weight:bold;margin-left:0%;">Principal Risks of Investing in the Portfolio.</span>
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	The risks summarized below are the principal risks of investing in the Portfolio. All investments have risks to some degree and it is possible that you could lose money by investing in the Portfolio.An investment in the Portfolio is not a deposit with a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. While the Portfolio makes every effort to achieve its objective, the Portfolio cannot guarantee success. The order of the below risk factors does not indicate the significance of any particular risk factor.Blend Style Risk. The Portfolio's blend investment style may subject the Portfolio to risks of both value and growth investing. The portion of the Portfolio's portfolio that makes investments pursuant to a growth strategy may be subject to above-average fluctuations as a result of seeking high quality stocks with good future growth prospects. The portion of the Portfolio's portfolio that makes investments pursuant to a value strategy may be subject to the risk that the market may not recognize a security's intrinsic value for long periods of time or that a stock judged to be undervalued may actually be appropriately priced. Issuers of value stocks may have experienced adverse business developments or may be subject to special risks that have caused the stock to be out of favor. If the Portfolio's assessment of market conditions or a company’s value is inaccurate, the Portfolio could suffer losses or produce poor performance relative to other funds. Historically, growth stocks have performed best during later stages of economic expansion and value stocks have performed best during periods of economic recovery. Therefore, both styles may over time go in and out of favor with the markets. At times when a style is out of favor, that portion of the portfolio may lag the other portion of the portfolio, which may cause the overall Portfolio to underperform the market in general, its benchmark and other mutual funds. Growth and value stocks have historically produced similar long-term results, though each category has periods when it outperforms the other.Economic and Market Events Risk. Events in the US and global financial markets, including actions taken by the US Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in periods of unusually high volatility in a market or a segment of a market, which could negatively impact performance. Reduced liquidity in credit and fixed income markets could adversely affect issuers worldwide.Equity Securities Risk. The value of a particular stock or equity-related security held by the Portfolio could fluctuate, perhaps greatly, in response to a number of factors, such as changes in the issuer’s financial condition or the value of the equity markets or a sector of those markets. Such events may result in losses to the Portfolio.Expense Risk. The actual cost of investing in the Portfolio may be higher than the expenses shown in the “Annual Portfolio Operating Expenses” table above for a variety of reasons, including, for example, if the Portfolio’s average net assets decrease.Foreign Investment Risk. Investments in foreign securities generally involve more risk than investments in securities of US issuers, including: changes in currency exchange rates may affect the value of foreign securities held by the Portfolio; foreign markets generally are more volatile than, and generally are not subject to regulatory requirements comparable to, US markets; foreign financial reporting standards usually differ from those in the US; foreign exchanges are often less liquid than US markets; political or social developments may adversely affect the value of foreign securities; foreign holdings may be subject to special taxation and limitations on repatriating investment proceeds; and certain events in foreign markets may adversely affect foreign and domestic issuers, including interruptions in the global supply chain, natural disasters and outbreaks of infectious diseases.Market and Management Risk. Markets in which the Portfolio invests may experience volatility and go down in value, and possibly sharply and unpredictably. Investment techniques, risk analyses and investment strategies, which may include quantitative models or methods, used by a subadviser in making investment decisions for the Portfolio are subject to human error and may not produce the intended or desired results. The value of the Portfolio’s investments may be negatively affected by the occurrence of domestic or global events,including war, terrorism, environmental disasters, natural disasters or events, political or civil instability, and public health emergencies (such as the spread of infectious diseases, pandemics, or epidemics), among others. Such events may reduce consumer demand or economic output, result in market closures, travel restrictions or quarantines, and significantly adversely impact the economy. There is no guarantee that the investment objective of the Portfolio will be achieved.Market Capitalization Risk. Investing in issuers within the same market capitalization category carries the risk that the category may be out of favor due to current market conditions or investor sentiment. Because the Portfolio may invest a portion of its assets in securities issued by small-cap companies, it is likely to be more volatile than a portfolio that focuses on securities issued by larger companies. Small-sized companies often have less experienced management, narrower product lines, more limited financial resources, and less publicly available information than larger companies. In addition, smaller companies are typically more sensitive to changes in overall economic conditions and their securities may be difficult to trade.Real Estate Risk. Investments in real estate investment trusts (REITs) and real estate-linked derivative instruments are subject to risks similar to those associated with direct ownership of real estate. Poor performance by the manager of the REIT and adverse changes to or inability to qualify with favorable tax laws will adversely affect the Portfolio. In addition, some REITs have limited diversification because they invest in a limited number of properties, a narrow geographic area, or a single type of property.Regulatory Risk. The Portfolio is subject to a variety of laws and regulations which govern its operations. The Portfolio is subject to regulation by the SEC, and depending on the Portfolio, the CFTC. Similarly, the businesses and other issuers of the securities and other instruments in which the Portfolio invests are also subject to considerable regulation. Changes in laws and regulations may materially impact the Portfolio, a security, business, sector or market.

Performance Narrative [Text Block]	rr_PerformanceNarrativeTextBlock	The bar chart and table provide some indication of the risks of investing in the Portfolio by showing changes in the Portfolio's performance from year to year and by showing how the Portfolio's average annual returns for 1, 5, and 10 years compare with those of a broad measure of market performance.Past performance does not mean that the Portfolio will achieve similar results in the future.The annual returns and average annual returns shown in the chart and table are after deduction of expenses and do not include Contract charges. If Contract charges were included, the returns shown would have been lower than those shown. Consult your Contract prospectus for information about Contract charges.The table also demonstrates how the Portfolio's performance compares to the returns of the Russell 1000 Index which includes stocks of companies with similar investment objectives. Annual return information is provided only for Class I shares. Because all of the Portfolio’s shares are invested in the same portfolio of securities, annual returns for Class II and Class III shares would be lower because Class II and Class III shares do not have the same expenses as Class I shares.
