This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and examples below. 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 the fund or shares of other funds in the BNY Mellon Family of Funds that are subject to a sales charge. More information about sales charges, including these and other discounts and waivers, is available from your financial professional and in the Shareholder Guide section beginning on page 13 of the prospectus, in the Appendix on page A-1 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.

Portfolio Turnover [Text Block] oef_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 230.46% of the average value of its portfolio.

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. 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 example and the first year of the three-, five- and ten-years examples are based on net operating expenses, which reflect the expense limitation agreement by BNY Mellon Investment Adviser, Inc. Although your actual costs may be higher or lower, based on these assumptions your costs would be:
Strategy [Heading] oef_StrategyHeading Principal Investment Strategy
Strategy Narrative [Text Block] oef_StrategyNarrativeTextBlock

To pursue its goal, the fund normally invests at least 80% of its net assets, plus any borrowings for investment purposes, in common stocks or securities convertible into common stocks of foreign companies and depositary receipts evidencing ownership in such securities. At least 75% of the fund's net assets will be invested in countries represented in the Morgan Stanley Capital International Europe, Australasia and Far East (MSCI EAFE®) Index. The fund may invest up to 25% of its net assets in stocks of companies located in countries (other than the United States) not represented in the MSCI EAFE Index, including up to 20% of its net assets in emerging market countries. The fund may, from time to time, invest a significant portion (more than 20%) of its net assets in securities of companies in certain countries.

The core of the investment philosophy of the fund's sub-adviser, Newton Investment Management Limited, an affiliate of BNY Mellon Investment Adviser, Inc., is the belief that no company, market or economy can be considered in isolation; each must be understood within a global context. The fund's sub-adviser believes that a global comparison of companies is the most effective method of stock analysis, and the sub-adviser's global industry analysts research investment opportunities by global sector rather than by region. The process begins by identifying a core list of investment themes that the fund's sub-adviser believes will positively or negatively affect certain sectors or industries and cause stocks within these sectors or industries to outperform or underperform others. The sub-adviser then identifies specific companies using these investment themes to help it focus on areas where thematic and strategic research indicates superior returns are likely to be achieved.

Sell decisions for individual stocks will typically be a result of one or more of the following:

· a price movement and market activity have created an excessive valuation;

· the valuation of the company has become expensive relative to its peers;

· there has been a significant change in the prospects of the company;

· there has been a change in the sub-adviser's view of global investment themes (as described above); or

· profit-taking.

In addition, at times, the fund may engage in active and frequent trading, which will increase portfolio turnover.

The fund may use derivative instruments as a substitute for investing directly in an underlying asset, to increase returns, to manage foreign currency risk, or as part of a hedging strategy. The derivative instruments in which the fund may invest typically include forward foreign currency exchange contracts.

Performance Narrative [Text Block] oef_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 I shares from year to year. 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. 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. Performance for each share class will vary due to differences in expenses. More recent performance information may be available at www.bny.com/investments.

Principal Risks

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.

BNY Mellon International Equity Fund | · Risks of stock investing  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

· 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 market conditions or because of factors that affect the particular company or the company's industry.
BNY Mellon International Equity Fund | · Foreign investment risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

· 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 and less publicly available company information, political and economic instability and differing auditing, accounting 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.

BNY Mellon International Equity Fund | · Emerging market risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

· Emerging market risk: The securities of issuers located or doing substantial business in emerging market countries tend to be more volatile and less liquid than the securities of issuers located in countries with more mature economies. Emerging markets generally have less diverse and less mature economic structures and less stable political systems than those of developed countries. Investments in these countries may be subject to political, economic, legal, market and currency risks. Special risks associated with investments in emerging market issuers may include a lack of publicly available information, a lack of uniform disclosure, auditing, accounting and financial reporting and recordkeeping standards and limited investor protections applicable in developed economies. The risks also may include unpredictable political and economic policies, additional transaction costs, delays in settlement procedures, unexpected market closures, the imposition of capital controls and/or foreign investment limitations by a country, nationalization of businesses and the imposition of sanctions or restrictions on certain investments by other countries, such as the United States.

BNY Mellon International Equity Fund | · Foreign currency risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

· Foreign currency risk: Investments in foreign currencies are subject to the risk that those currencies will decline in value relative to the U.S. dollar or, in the case of hedged positions, that the U.S. dollar will decline relative to the currency being hedged. Foreign currencies, particularly the currencies of emerging market countries, are also subject to risks caused by inflation, interest rates, budget deficits and low savings rates, political factors and government intervention and controls.
BNY Mellon International Equity Fund | · Derivatives risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

· 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, and the fund's use of derivatives may result in losses to the fund and increased portfolio volatility. Derivatives in which the fund may invest can be highly volatile, illiquid and difficult to value, and there is the risk that changes in the value of a derivative held by the fund will not correlate with the underlying assets or the fund's other investments in the manner intended.

BNY Mellon International Equity Fund | · Liquidity risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

· Liquidity risk: When there is little or no active trading market for specific types of securities, it can become more difficult to sell the securities in a timely manner at or near their perceived value. In such a market, the value of such securities and the fund's share price may fall dramatically. Investments that are illiquid or that trade in lower volumes may be more difficult to value. Investments in foreign securities, particularly those of issuers located in emerging markets, tend to have greater exposure to liquidity risk than domestic securities.
BNY Mellon International Equity Fund | · Country, company, industry and market sector risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

· Country, company, industry and market sector risk: The fund may be overweighted or underweighted, relative to the MSCI EAFE Index, in certain countries, companies, industries or market sectors, which may cause the fund's performance to be more or less sensitive to positive or negative developments affecting those countries, companies, industries or sectors. In addition, the fund may, from time to time, invest a significant portion (more than 20%) of its total assets in securities of companies located in particular countries, depending on such country's representation within the MSCI EAFE Index.
BNY Mellon International Equity Fund | · Market risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

· Market risk: The value of the securities in which the fund invests may be affected by political, regulatory, economic and social developments, and developments that impact specific economic sectors, industries or segments of the market.  In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or fixed-income markets may negatively affect many issuers, which could adversely affect the fund.  Global economies and financial markets are becoming increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market.  These risks may be magnified if certain events or developments adversely interrupt the global supply chain; in these and other circumstances, such risks might affect companies world-wide.  Local, regional or global events such as war, military conflicts, acts of terrorism, natural disasters, the spread of infectious illness or other public health issues, recessions, elevated levels of government debt, changes in trade regulation or economic sanctions, internal unrest and discord, or other events could have a significant impact on the fund and its investments. 

BNY Mellon International Equity Fund | · Portfolio turnover risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

· Portfolio turnover risk: The fund may engage in short-term trading, which could produce higher transaction costs and taxable distributions, and lower the fund's after-tax performance.

BNY Mellon International Equity Fund | · Management risk  
Risk/Return: oef_RiskReturnAbstract  
Risk [Text Block] oef_RiskTextBlock

· Management risk: The investment process used by the fund's sub-adviser could fail to achieve the fund's investment goal and cause your fund investment to lose value.
