Expense [Heading]	rr_ExpenseHeading	Fees and Expenses of the Fund
Expense Narrative [Text Block]	rr_ExpenseNarrativeTextBlock	This table describes the fees and expenses that are incurred, directly or indirectly, when a variable product owner buys, holds, or redeems an interest in an insurance company separate account that invests in the Series II shares of the Fund but does not represent the effect of any fees or other expenses assessed in connection with your variable product, and if it did, expenses would be higher.

Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	The Fund 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 fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 11% of the average value of its portfolio.

Expense Example [Heading]	rr_ExpenseExampleHeading	Example.
Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example does not represent the effect of any fees or other expenses assessed in connection with your variable product, and if it did, expenses would be higher. The Example assumes that you invest $10,000 in the Fund 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 Fund’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 of the Fund
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund will invest, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in common stocks of companies which pay dividends and other instruments that have economic characteristics similar to such securities. The Fund invests primarily in dividend-paying equity securities. The principal type of equity security in which the Fund invests is common stock. The Fund invests in securities that the portfolio managers believe are undervalued based on various valuation measures. The Fund may invest up to 25% of its net assets in securities of foreign issuers. The Fund may also invest up to 20% of its net assets in investment-grade debt securities of U.S. issuers. In selecting investments, the portfolio managers seek to identify dividend-paying issuers with strong profitability, solid balance sheets and capital allocation policies that support sustained or increasing dividends and share repurchases. Through fundamental research, financial statement analysis and the use of several valuation techniques, the management team estimates a target price for each security over a 2-3 year investment horizon. The portfolio managers manage risk utilizing a valuation framework, careful stock selection and a rigorous buy-and-sell discipline and incorporate an assessment of the potential reward relative to the downside risk to determine a fair valuation over the investment horizon. When evaluating cyclical businesses, the management team seeks companies that have normalized earnings power greater than that implied by their current market valuation and that return capital to shareholders via dividends and share repurchases. The portfolio managers then construct a portfolio they believe provides the best total return profile, which is created by seeking a combination of price appreciation potential, dividend income and capital preservation. The portfolio managers maintain a rigorous sell discipline and consider selling or trimming a stock when it no longer materially meets our investment criteria, including when (1) a stock reaches its fair valuation (target price); (2) a company’s fundamental business prospects deteriorate; or (3) a more attractive investment opportunity presents itself.
Risk [Heading]	rr_RiskHeading	Principal Risks of Investing in the Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency. The risks associated with an investment in the Fund can increase during times of significant market volatility. The principal risks of investing in the Fund are: Call Risk. If interest rates fall, it is possible that issuers of debt securities with high interest rates will prepay or call their securities before their maturity dates. In this event, the proceeds from the called securities would likely be reinvested by the Fund in securities bearing the new, lower interest rates, resulting in a possible decline in the Fund’s income and distributions to shareholders. Credit Risk. The issuer of instruments in which the Fund invests may be unable to meet interest and/or principal payments, thereby causing its instruments to decrease in value and lowering the issuer’s credit rating. Foreign Securities Risk. The Fund’s foreign investments may be affected by changes in a foreign country’s exchange rates, political and social instability, changes in economic or taxation policies, difficulties when enforcing obligations, decreased liquidity, and increased volatility. Foreign companies may be subject to less regulation resulting in less publicly available information about the companies. Interest Rate Risk. Interest rate risk refers to the risk that bond prices generally fall as interest rates rise; conversely, bond prices generally rise as interest rates fall. Specific bonds differ in their sensitivity to changes in interest rates depending on their individual characteristics, including duration. Management Risk. The investment techniques and risk analysis used by the Fund’s portfolio managers may not produce the desired results. Market Risk. The prices of and the income generated by the Fund’s securities may decline in response to, among other things, investor sentiment; general economic and market conditions; regional or global instability; and currency and interest rate fluctuations. Value Investing Style Risk. The Fund emphasizes a value style of investing, which focuses on undervalued companies with characteristics for improved valuations. This style of investing is subject to the risk that the valuations never improve or that the returns on value equity securities are less than returns on other styles of investing or the overall stock market. Value stocks also may decline in price, even though in theory they are already underpriced.
Risk Lose Money [Text]	rr_RiskLoseMoney	As with any mutual fund investment, loss of money is a risk of investing.

Bar Chart and Performance Table [Heading]	rr_BarChartAndPerformanceTableHeading	Performance Information
Performance Narrative [Text Block]	rr_PerformanceNarrativeTextBlock	The bar chart and performance table provide an indication of the risks of investing in the Fund. The bar chart shows changes in the performance of the Fund from year to year as of December 31. The performance table compares the Fund’s and the Morgan Stanley Variable Investment Series Dividend Growth Portfolio’s (the predecessor fund) performance to that of a broad-based securities market benchmark, a style specific benchmark and a peer group benchmark comprised of funds with investment objectives and strategies similar to those of the Fund. The bar chart and performance table below do not reflect charges assessed in connection with your variable product; if they did, the performance shown would be lower. The Fund’s and the predecessor fund past performance is not necessarily an indication of its future performance. The returns shown prior to June 1, 2010 are those of the Class Y shares of the predecessor fund, which are not offered by the Fund. The predecessor fund was advised by Morgan Stanley Investment Advisors Inc. The predecessor fund was reorganized into Series II shares of the Fund on June 1, 2010. Series II shares’ returns will be different from the predecessor fund as they have different expenses. All performance shown assumes the reinvestment of dividends and capital gains. Series I shares are not offered by this prospectus. The Series I shares and Series II shares invest in the same portfolio of securities and will have substantially similar performance, except to the extent that the expenses borne by each share class differ. Series II shares have higher expenses (and therefore lower performance) resulting from its Rule 12b-1 plan, which provides for a maximum fee equal to an annual rate of 0.25% (expressed as a percentage of average daily net assets of the Fund).
