| Expense Narrative [Text Block] | rr_ExpenseNarrativeTextBlock | This table describes the fees and expenses that you may pay if you buy and hold shares of the fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in certain funds in the Dreyfus Family of Funds. More information about these and other discounts is available from your financial professional and in the Shareholder Guide section beginning on page 8 of the Prospectus and in the How to Buy Shares section and the Additional Information About How to Buy Shares section beginning on page II-1 and page III-1, respectively, of the fund's Statement of Additional Information. Class A shares bought without an initial sales charge as part of an investment of $1 million or more may be charged a deferred sales charge of 1.00% if redeemed within one year. |

| 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 may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. 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 61.52% 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 the fund with the cost of investing in other mutual funds. 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. The one-year examples and the first year of the three-, five-, and ten-year examples are based on net operating expenses, which reflect the expense waiver/reimbursement by The Dreyfus Corporation. Although your actual costs may be higher or lower, based on these assumptions your costs would be: |
||||
| Expense Example, No Redemption, By Year, Caption [Text] | rr_ExpenseExampleNoRedemptionByYearCaption | You would pay the following expenses if you did not redeem your shares: | ||||
| Strategy [Heading] | rr_StrategyHeading | Principal Investment Strategy | ||||
| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | To pursue its goal, the fund normally invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities of large capitalization companies. The fund considers large-cap companies to be those companies with market capitalizations of $5 billion or more at the time of purchase. The fund's investment philosophy is based on the premise that earnings growth is the primary determinant of long term stock appreciation. With this, the fund's portfolio manager uses an approach that combines top-down and bottom-up analysis. Therefore, stock selection and sector allocation are both factors in determining the fund's holdings. Fundamental financial analysis is used to identify companies that the portfolio manager believes offer one or more of the following characteristics, among others: · expected earnings growth rate exceeds market and industry trends; · potential for positive earnings surprise relative to market expectations; · positive operational or financial catalysts; · attractive valuation based on growth prospects; and · strong financial condition. The fund may use listed equity options to seek to enhance returns and/or mitigate risk. The fund will engage in "covered" option transactions only, where the fund has in its possession, for the duration of the strategy, the underlying physical asset or cash to satisfy any obligation the fund may have with respect to the option strategy. The fund will limit investments in options to 20% (based on the notional value of the options) of the fund's total assets and will limit the value of all total premiums paid or received to 5% of the fund's total assets. |
||||
| Strategy Portfolio Concentration [Text] | rr_StrategyPortfolioConcentration | To pursue its goal, the fund normally invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities of large capitalization companies. | ||||
| Risk [Heading] | rr_RiskHeading | Principal Risks | ||||
| Risk Narrative [Text Block] | rr_RiskNarrativeTextBlock | An investment in the fund is not a bank deposit. It is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. It is not a complete investment program. The fund's share price fluctuates, sometimes dramatically, which means you could lose money. · Risks of stock investing. Stocks generally fluctuate more in value than bonds and may decline significantly over short time periods. There is the chance that stock prices overall will decline because stock markets tend to move in cycles, with periods of rising prices and falling prices. The market value of a stock may decline due to general weakness in the stock market or because of factors that affect the company or its particular industry. · Large cap stock risk. To the extent the fund invests in large capitalization stocks, the fund may underperform funds that invest primarily in the stocks of lower quality, smaller capitalization companies during periods when the stocks of such companies are in favor. · Growth stock risk. Investors often expect growth companies to increase their earnings at a certain rate. If these expectations are not met, investors can punish the stocks inordinately, even if earnings do increase. In addition, growth stocks may lack the dividend yield that may cushion stock prices in market downturns. · Derivatives risk. A small investment in derivatives could have a potentially large impact on the fund's performance. The use of derivatives involves risks different from, or possibly greater than, the risks associated with investing directly in the underlying assets. Derivatives can be highly volatile, illiquid and difficult to value. |

| Bar Chart and Performance Table [Heading] | rr_BarChartAndPerformanceTableHeading | Performance | ||||
| Performance Narrative [Text Block] | rr_PerformanceNarrativeTextBlock | The following bar chart and table provide some indication of the risks of investing in the fund. The bar chart shows changes in the performance of the fund's Class A shares from year to year. The table compares the average annual total returns of the fund's shares to those of a broad measure of market performance. The fund's past performance (before and after taxes) is not necessarily an indication of how the fund will perform in the future. Sales charges, if any, are not reflected in the bar chart, and if those charges were included, returns would have been less than those shown. More recent performance information may be available at www.dreyfus.com. For periods prior to September 13, 2008, the information below represents the performance of the predecessor fund's Class A shares (with respect to the fund's Class A and C shares) and the predecessor fund's Institutional shares (with respect to the fund's Class I shares) adjusted to reflect each share class' applicable sales charge. Such performance figures have not been adjusted to reflect applicable class fees and expenses; if such fees and expenses had been reflected, the performance shown for Class A and Class C for such periods may have been lower. |

| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | To pursue its goal, the fund normally invests at least 80% of its net assets, plus any borrowings for investment purposes, in publicly-traded equity securities of companies principally engaged in the real estate sector. The fund normally invests in a global portfolio of equity securities of real estate companies, including real estate investment trusts (REITs) and real estate operating companies, with principal places of business located in, but not limited to, the developed markets of Europe, Australia, Asia and North America (including the United States). Although the fund invests primarily in developed markets, it also may invest in equity securities of companies located in emerging market countries, and may invest in equity securities of companies of any market capitalization, including smaller companies. In selecting investments for the fund's portfolio, Urdang Securities Management, Inc. (Urdang), the fund's sub-investment adviser, uses a proprietary approach to quantify investment opportunity from both a real estate and stock perspective. Generally, Urdang combines top-down real estate research and its relative value model securities valuation process. In conducting its bottom-up research, Urdang engages in an active analysis process that includes regular and direct contact with the companies in the fund's investable universe. These research efforts are supported with extensive sell side and independent research. Through the use of the proprietary relative value model, Urdang seeks to establish the validity of the price of a security relative to its peers by providing statistically significant solutions to business- and management-related uncertainties, such as the impact on value of leverage, growth rate, market capitalization and property type. |

| Risk Narrative [Text Block] | rr_RiskNarrativeTextBlock | An investment in the fund is not a bank deposit. It is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. It is not a complete investment program. The fund's share price fluctuates, sometimes dramatically, which means you could lose money. · Risks of stock investing. Stocks generally fluctuate more in value than bonds and may decline significantly over short time periods. There is the chance that stock prices overall will decline because stock markets tend to move in cycles, with periods of rising prices and falling prices. The market value of a stock may decline due to general weakness in the stock market or because of factors that affect the company or its particular industry. · Real estate sector risk. The securities of issuers that are principally engaged in the real estate sector may be subject to declines in real estate values, defaults by mortgagors or other borrowers and tenants, increases in property taxes and operating expenses, overbuilding, fluctuations in rental income, changes in interest rates, possible lack of availability of mortgage funds or financing, extended vacancies of properties, changes in tax and regulatory requirements (including zoning laws and environmental restrictions), losses due to costs resulting from the clean-up of environmental problems, liability to third parties for damages resulting from environmental problems, and casualty or condemnation losses. · Foreign investment risk. To the extent the fund invests in foreign securities, the fund's performance will be influenced by political, social and economic factors affecting investments in foreign issuers. Special risks associated with investments in foreign issuers include exposure to currency fluctuations, less liquidity, less developed or less efficient trading markets, lack of comprehensive company information, political and economic instability and differing auditing and legal standards. Investments denominated in foreign currencies are subject to the risk that such currencies will decline in value relative to the U.S. dollar and affect the value of these investments held by the fund. · Emerging market risk. The securities of issuers located in emerging markets tend to be more volatile and less liquid than securities of issuers located in more mature economies, and emerging markets generally have less diverse and less mature economic structures and less stable political systems than those of developed countries. The securities of issuers located or doing substantial business in emerging markets are often subject to rapid and large changes in price. · Small and midsize company risk. Small and midsize companies carry additional risks because the operating histories of these companies tend to be more limited, their earnings and revenues less predictable (and some companies may be experiencing significant losses), and their share prices more volatile than those of larger, more established companies. The shares of smaller companies tend to trade less frequently than those of larger, more established companies, which can adversely affect the pricing of these securities and the fund's ability to sell these securities. · Liquidity risk. When there is little or no active trading market for a security, the fund may not be able to sell the security in a timely manner at its perceived value, which could cause the fund's share price to fall. Investments in foreign securitiies, particularly those of issuers located in emerging markets, tend to have greater exposure to liquidity risk than domestic securities. |
