Risk Lose Money [Member]
Prospectus [Line Items]
Risk [Text Block]	The fund is subject to risks, any of which could cause an investor to lose money.
Market Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Market Risk. Financial markets rise and fall in response to a variety of factors, sometimes rapidly and unpredictably. Markets may be impacted by economic, political, regulatory and other conditions, including economic sanctions, tariffs and other government actions. In addition, the occurrence of global events, such as war, terrorism, environmental disasters, natural disasters and epidemics, may also negatively affect the financial markets. As with any investment whose performance is tied to these markets, the value of an investment in the fund will fluctuate, which means that an investor could lose money over short or long periods.
Multi-Manager Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Multi-Manager Risk. Each subadviser makes investment decisions independently, and it is possible that the investment styles of subadvisers may not complement one another. As a result, the fund’s exposure to a given stock, industry or investment style could unintentionally be smaller or larger than if the fund had a single subadviser.
Management Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Management Risk. As with all actively managed funds, the fund is subject to the risk that the subadvisers will select investments or allocate assets in a manner that could cause the fund to underperform or otherwise not meet its investment objective. The fund’s subadvisers apply their own investment techniques and risk analyses in making investment decisions for the fund, but there can be no guarantee that they will produce the desired results.
Equity Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Equity Risk. The prices of equity securities rise and fall daily. These price movements may result from factors affecting individual companies, industries or the securities market as a whole. In addition, equity markets tend to move in cycles, which may cause stock prices to fall over short or extended periods of time.
Market Capitalization Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Market Capitalization Risk. Securities issued by companies of different market capitalizations tend to go in and out of favor based on market and economic conditions. During a period when securities of a particular market capitalization fall behind other types of investments, the fund’s performance could be impacted.
Large-Cap Company Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Large-Cap Company Risk. Large-cap companies are generally more mature and the securities issued by these companies may not be able to reach the same levels of growth as the securities issued by small- or mid-cap companies.
Growth Investing Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Growth Investing Risk. Growth stocks can be volatile. Growth companies usually invest a high portion of earnings in their businesses and may lack the dividends of value stocks that can cushion stock prices in a falling market. The prices of growth stocks are based largely on projections of the issuer’s future earnings and revenues. If a company’s earnings or revenues fall short of expectations, its stock price may fall dramatically. Growth stocks may also be more expensive relative to their earnings or assets compared to value or other stocks.
Foreign Investment Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Foreign Investment Risk. The fund’s investments in securities of foreign issuers involve certain risks that may be greater than those associated with investments in securities of U.S. issuers. These include risks of adverse changes in foreign economic, political, regulatory and other conditions; changes in currency exchange rates or exchange control regulations (including limitations on currency movements and exchanges); the imposition of economic sanctions or other government restrictions; differing accounting, auditing, financial reporting and legal standards and practices; differing securities market structures; and higher transaction costs. These risks may negatively impact the value or liquidity of the fund’s investments, and could impair the fund’s ability to meet its investment objective or invest in accordance with its investment strategy. There is a risk that investments in securities denominated in, and/or receiving revenues in, foreign 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 hedged, resulting in the dollar value of the fund’s investment being adversely affected. Foreign securities also include American Depositary Receipts (ADRs), Global Depositary Receipts (GDRs) and European Depositary Receipts (EDRs) which may be less liquid than the underlying shares in their primary trading market and GDRs, many of which are issued by companies in emerging markets, may be more volatile. These risks may be heightened in connection with investments in emerging markets or securities of issuers that conduct their business in emerging markets.
Derivatives Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Derivatives Risk. The fund’s use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. The fund’s use of derivatives could reduce the fund’s performance, increase its volatility and cause the fund to lose more than the initial amount invested. In addition, investments in derivatives may involve leverage, which means a small percentage of assets invested in derivatives can have a disproportionately large impact on the fund.
Leverage Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Leverage Risk. Certain fund transactions, such as derivatives transactions, may give rise to a form of leverage and may expose the fund to greater risk. Leverage tends to magnify the effect of any increase or decrease in the value of the fund’s portfolio securities, which means even a small amount of leverage can have a disproportionately large impact on the fund.
Liquidity Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Liquidity Risk. The fund may be unable to sell certain securities, such as illiquid securities, readily at a favorable time or price, or the fund may have to sell them at a loss.
