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 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 Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 95% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading <span style="color:#000000;font-family:Arial Narrow;font-size:11pt;font-weight:bold;">What are the Fund’s main investment strategies?</span>
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock The Fund invests primarily in equity securities issued by companies with principal business activities in Western Europe. Under normal market conditions, the Fund invests at least 80% of the value of its Assets in equity securities of European issuers. “Assets” means net assets, plus the amount of borrowings for investment purposes. The equity securities in which the Fund may invest include, but are not limited to, common stock, preferred stock, convertible securities, trust or partnership interests, depositary receipts and warrants and rights. The Fund may utilize exchange-traded futures for the efficient management of cash flows. The Fund may invest in Austria, Belgium, Denmark, Germany, Finland, France, Greece, Ireland, Italy, Luxembourg, the Netherlands, Norway, Portugal, Spain, Sweden, Switzerland, and the United Kingdom, as well as other Western European countries which the adviser believes are appropriate. In addition, the Fund may invest up to 8% of its Assets in equity securities of emerging market European issuers. These countries may include Poland, the Czech Republic, Hungary and other countries with similar economic profiles which the adviser believes are appropriate. The Fund may invest in securities denominated in U.S. dollars, other major reserve currencies, such as the euro, yen and pound sterling, and currencies of other countries in which it can invest. The adviser may adjust the Fund’s exposure to each currency based on its view of the markets and issuers. It may increase or decrease the emphasis on a type of security, sector, country or currency, based on its analysis of a variety of economic factors, including fundamental economic strength, earnings growth, quality of management, sector growth, credit quality and interest rate trends. The Fund may purchase securities where the issuer is located in one country but the security is denominated in the currency of another. While the Fund’s assets will usually be invested in a number of different Western European countries, the Fund may at times invest most or all of the assets in a limited number of these countries. The Fund will, however, try to choose a wide range of industries and companies of varying sizes. While the Fund invests primarily in equities, it may also invest in debt securities rated as investment grade by Moody’s Investors Service Inc. (Moody’s), Standard & Poor’s Corporation (S&P) or Fitch Ratings (Fitch) or the equivalent by another national rating organization, meaning that such securities will carry a minimum rating of Baa3, BBB–, or BBB–, respectively, or in securities that are unrated but are deemed by the adviser to be of comparable quality. No more than 20% of the Fund’s assets will be invested in debt securities denominated in a currency other than the U.S. dollar. No more than 20% of the Fund’s assets will be invested in debt securities issued by a single foreign government or international organization, such as the World Bank. The Fund may also invest in corporate bonds, municipal bonds, inflation-linked debt securities and debt securities issued by governmental entities and private issuers. Investment Process: In managing the Fund, the adviser uses a bottom-up stock selection process that focuses on the value, quality and momentum characteristics to decide which securities to buy and sell. As part of its investment process, the adviser seeks to assess the impact of environmental, social and governance (ESG) factors on many issuers in the universe in which the Fund may invest. The adviser’s assessment is based on an analysis of key opportunities and risks across industries to seek to identify financially material issues with respect to the Fund’s investments in securities and ascertain key issues that merit engagement with issuers. These assessments may not be conclusive and securities of issuers that may be negatively impacted by such factors may be purchased and retained by the Fund while the Fund may divest or not invest in securities of issuers that may be positively impacted by such factors.

A C I Shares | JPMorgan Europe Dynamic Fund | Equity Market Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s portfolio securities goes down, your investment in the Fund decreases in value.
A C I Shares | JPMorgan Europe Dynamic Fund | General Market Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in general financial markets, a particular financial market or other asset classes due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics.
A C I Shares | JPMorgan Europe Dynamic Fund | Foreign Securities and Emerging Markets Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Foreign Securities and Emerging Markets Risk. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, unstable governments, civil conflicts and war, greater volatility, decreased market liquidity, expropriation and nationalization risks, sanctions or other measures by the United States or other governments, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered or receive delivery of securities paid for and may be subject to increased risk that the counterparty will fail to make payments or delivery when due or default completely. Foreign market trading hours, clearance and settlement procedures, and holiday schedules may limit the Fund’s ability to buy and sell securities. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.” Emerging market countries typically have less established market economies than developed countries and may face greater social, economic, regulatory and political uncertainties. In addition, emerging markets typically present greater illiquidity and price volatility concerns due to smaller or limited local capital markets and greater difficulty in determining market valuations of securities due to limited public information on issuers. Certain emerging market countries may be subject to less stringent requirements regarding accounting, auditing, financial reporting and record keeping and therefore, material information related to an investment may not be available or reliable. Additionally, the Fund may have substantial difficulties exercising its legal rights or enforcing a counterparty’s legal obligations in certain jurisdictions outside of the United States, in particular in emerging markets countries, which can increase the risks of loss.
A C I Shares | JPMorgan Europe Dynamic Fund | Geographic Focus Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Geographic Focus Risk. The Fund may focus its investments in one or more regions or small groups of countries. As a result, the Fund’s performance may be subject to greater volatility than a more geographically diversified fund.
A C I Shares | JPMorgan Europe Dynamic Fund | European Market Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock European Market Risk. The Fund’s performance will be affected by political, social and economic conditions in the various countries in which it invests in Europe and in Europe more generally, such as growth of the economic output (the gross national product), the rate of inflation, the rate at which capital is reinvested into European economies, the success of governmental actions to reduce budget deficits, the resource self-sufficiency of European countries and interest and monetary exchange rates between European countries. European financial markets may experience volatility due to concerns about high government debt levels, credit rating downgrades, rising unemployment, the future of the euro as a common currency, possible restructuring of government debt and other government measures responding to those concerns, and fiscal and monetary controls imposed on member countries of the European Union.
A C I Shares | JPMorgan Europe Dynamic Fund | Derivatives Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Derivatives Risk. Derivatives, including futures, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Certain derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the security or other risk being hedged. In addition, given their complexity, derivatives may expose the Fund to risks of mispricing or improper valuation. Derivatives also can expose the Fund to derivative liquidity risk, which includes the risks involving the liquidity demands that derivatives can create to make payments of margin, collateral or settlement payments to counterparties, legal risk, which includes the risk of loss resulting from insufficient or unenforceable contractual documentation, insufficient capacity or authority of a Fund’s counterparty and operational risk, which includes documentation or settlement issues, system failures, inadequate controls and human error.
A C I Shares | JPMorgan Europe Dynamic Fund | Currency Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and may affect the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment impacted by that currency loses value because that currency is worth less in U.S. dollars. Currency exchange rates may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets, may be riskier than other types of investments and may increase the volatility of the Fund. Although the Fund may attempt to hedge some or all of its currency exposure into the U.S. dollar, it may not be successful in reducing the effects of currency fluctuations. The Fund may also hedge from one foreign currency to another. In addition, the Fund’s use of currency hedging may not be successful, including due to delays in placing trades and other operational limitations, and the use of such strategies may lower the Fund’s potential returns.
A C I Shares | JPMorgan Europe Dynamic Fund | Smaller Company Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Smaller Company Risk. Investments in securities of smaller companies (mid cap and small cap companies) may be riskier, less liquid, more volatile and more vulnerable to economic, market and industry changes than securities of larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. As a result, changes in the price of securities issued by such companies may be more sudden or erratic than the prices of securities of large capitalization companies, especially over the short term. These risks are higher for small cap companies.
A C I Shares | JPMorgan Europe Dynamic Fund | High Portfolio Turnover Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock High Portfolio Turnover Risk. The Fund may engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility that the recognition of capital gains will be accelerated, including short-term capital gains that will generally be taxable to shareholders as ordinary income.
A C I Shares | JPMorgan Europe Dynamic Fund | Industry and Sector Focus Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Industry and Sector Focus Risk. At times, the Fund may increase the relative emphasis of its investments in a particular industry or sector. The prices of securities of issuers in a particular industry or sector may be more susceptible to fluctuations due to changes in economic or business conditions, government regulations, availability of basic resources or supplies, contagion risk within a particular industry or sector or to other industries or sectors, or other events that affect that industry or sector more than securities of issuers in other industries and sectors. To the extent that the Fund increases the relative emphasis of its investments in a particular industry or sector, the value of the Fund’s shares may fluctuate in response to events affecting that industry or sector.
A C I Shares | JPMorgan Europe Dynamic Fund | Transactions Risk [Member]  
Risk Return Abstract rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock Transactions Risk. The Fund could experience a loss and its liquidity may be negatively impacted when selling securities to meet redemption requests. The risk of loss increases if the redemption requests are unusually large or frequent or occur in times of overall market turmoil or declining prices. Similarly, large purchases of Fund shares may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

[2] The Fund’s adviser and/or its affiliates have contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding acquired fund fees and expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, expenses related to trustee elections, and extraordinary expenses) exceed 1.24%, 1.74% and 0.99% of the average daily net assets of Class A, Class C and Class I Shares, respectively. The Fund may invest in one or more money market funds advised by the adviser or its affiliates (affiliated money market funds). The Fund’s adviser, shareholder servicing agent and/or administrator have contractually agreed to waive fees and/or reimburse expenses in an amount sufficient to offset the respective net fees each collects from the affiliated money market funds on the Fund’s investment in such money market funds. These waivers are in effect through 2/28/26, at which time it will be determined whether such waivers will be renewed or revised. To the extent that the Fund engages in securities lending, affiliated money market fund fees and expenses resulting from the Fund’s investment of cash received from securities lending borrowers are not included in Total Annual Fund Operating Expenses and therefore, the above waivers do not apply to such investments.
