Expense Narrative [Text Block] rr_ExpenseNarrativeTextBlock
The table below 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 for Class A shares if you and your family invest, or agree to invest in the future, at least $50,000 in certain classes of Hartford mutual funds or 529 plans administered by Hartford Funds Management Company, LLC. More information about these and other discounts is available from your financial professional and in the “How Sales Charges Are Calculated” section beginning on page 71 of the Fund’s statutory prospectus. Descriptions of any financial intermediary specific sales charge waivers and discounts are set forth in Appendix A to the statutory prospectus. In addition, the table and examples below do not reflect any transaction fees that may be charged by financial intermediaries or commissions that a shareholder may be required to pay directly to its financial intermediary when buying or selling Class I, Class R6, Class Y, or Class F shares. Please contact your financial intermediary for more information regarding whether you may be required to pay a transaction fee or a commission.

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 examples, affect the Fund’s performance. During the fiscal year ended October 31, 2019, the blended portfolio turnover rate of the Fund and its former master portfolio, the Global Impact Master Portfolio (the “Master Portfolio”), was 108%. This reflects the portfolio turnover rate of the Master Portfolio from November 1, 2018 through October 4, 2019 and the Fund from October 7, 2019 to October 31, 2019. For the period of October 7, 2019 (commencement of operations as a stand-alone fund) through October 31, 2019, the Fund's portfolio turnover rate was 5% of the average value of its portfolio.

Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock
The examples below are intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The examples assume that:

You invest $10,000

Your investment has a 5% return each year

The Fund’s operating expenses remain the same (except that the examples reflect the expense limitation arrangements for only the first year)

You reinvest all dividends and distributions

You pay any deferred sales charge due for the applicable period.

Your actual costs may be higher or lower. Based on these assumptions, you would pay the following expenses if you sell all of your shares at the end of each time period indicated:

Strategy [Heading] rr_StrategyHeading Principal Investment Strategy.
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Fund seeks to achieve its objective by investing in equity securities of issuers located throughout the world, including non-dollar securities and securities of emerging market issuers. The Fund will normally invest at least 80% of its assets in securities of issuers that Wellington Management Company LLP (“Wellington Management”), the Fund’s sub-adviser, determines meet its impact investing criteria.

For purposes of determining which companies meet its impact investing criteria, Wellington Management uses its proprietary research to identify companies that focus their operations in areas that it believes are likely to address major social and environmental challenges. As of February 28, 2020, these areas include sustainable agriculture and nutrition, health, clean water and sanitation, affordable housing, education and job training, financial inclusion, narrowing the digital divide, alternative energy, resource stewardship, resource efficiency, and safety and security. These areas are subject to change without notice to shareholders. Within this universe of companies, Wellington Management conducts fundamental analysis to identify what it believes to be attractive investments across economic sectors within both developed and emerging countries. As part of its fundamental analysis, Wellington Management evaluates a company's industry structure, asset quality, business environment, management quality, balance sheet, income statement, anticipated earnings, growth prospects, revenues and dividends, and other related measures or indicators of value, including certain environmental, social and/or governance (ESG) factors. The Fund may invest in companies of any market capitalization, including small and mid capitalization securities, located anywhere in the world, including the United States. The Fund may also invest in depositary receipts or other securities that are convertible into securities of foreign issuers and could, at times hold a portion of its assets in cash.

Under normal circumstances, the Fund will invest at least 40% of its net assets in foreign securities or derivative instruments or other investments with exposure to foreign securities of at least three different countries outside the United States. During periods of unfavorable market conditions, the Fund may reduce its exposure to foreign securities, but typically will continue to invest at least 30% of its net assets in foreign securities as described above.

Investments are deemed to be “foreign” if: (a) an issuer’s domicile or location of headquarters is in a foreign country; (b) an issuer derives a significant proportion (at least 50%) of its revenues or profits from goods produced or sold, investments made, or services performed in a foreign country or has at least 50% of its assets situated in a foreign country; (c) the principal trading market for a security is located in a foreign country; or (d) it is a foreign currency.
Risk [Heading] rr_RiskHeading PRINCIPAL RISKS.
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock
The principal risks of investing in the Fund are described below. When you sell your shares they may be worth more or less than what you paid for them, which means that you could lose money as a result of your investment. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. As with any fund, there is no guarantee that the Fund will achieve its investment objective.

Market Risk −Market risk is the risk that one or more markets in which the Fund invests will go down in value, including the possibility that the markets will go down sharply and unpredictably. Securities of a company may decline in value due to its financial prospects and activities, including certain operational impacts, such as data breaches and cybersecurity attacks. Securities may also decline in value due to general market and economic movements and trends, including adverse changes to credit markets.

Equity Risk −The risk that the price of equity or equity related securities may decline due to changes in a company's financial condition and overall market and economic conditions.

Mid Cap and Small Cap Securities Risk −Investments in mid- and small-capitalization companies involve greater risks than investments in larger, more established companies. Many of these companies are young and have limited operating or business history. These securities may be subject to more abrupt or erratic price movements and may lack sufficient market liquidity, and these issuers often face greater business risks, including the risk of bankruptcy.

Foreign Investments Risk −Investments in foreign securities may be riskier, more volatile, and less liquid than investments in U.S. securities. Differences between the U.S. and foreign regulatory regimes and securities markets, including the less stringent investor protection and disclosure standards of some foreign markets, as well as political and economic developments in foreign countries and regions and the U.S. (including the imposition of sanctions, tariffs, or other governmental restrictions), may affect the value of the Fund’s investments in foreign securities. Changes in currency exchange rates may also adversely affect the Fund’s foreign investments. The impact of the United Kingdom’s departure from the European Union, commonly known as “Brexit,” and the potential departure of one or more other countries from the European Union may have significant political and financial consequences for global markets. This may adversely impact Fund performance.

Emerging Markets Risk −The risks related to investing in foreign securities are generally greater with respect to investments in companies that conduct their principal business activities in emerging markets or whose securities are traded principally on exchanges in emerging markets. The risks of investing in emerging markets include risks of illiquidity, increased price volatility, smaller market capitalizations, less government regulation, less extensive and less frequent accounting, financial and other reporting requirements, significant delays in settlement of trades, risk of loss resulting from problems in share registration and custody and substantial economic and political disruptions. Frontier markets are those emerging markets that are considered to be among the smallest, least mature and least liquid, and as a result, the risks of investing in emerging markets are magnified in frontier markets.

Currency Risk −The risk that the value of the Fund’s investments in foreign securities or currencies will be affected by the value of the applicable currency relative to the U.S. dollar. When the Fund sells a foreign currency or foreign currency denominated security, its value may be worth less in U.S. dollars even if the investment increases in value in its local market. U.S. dollar-denominated securities of foreign issuers may also be affected by currency risk, as the revenue earned by issuers of these securities may also be affected by changes in the issuer’s local currency.

Impact Investing Risk −The Fund intends to invest in companies whose core business seeks to address the world’s major social and environmental challenges. This investment focus may affect the Fund’s exposure to certain companies or industries and the Fund may forego certain investment opportunities. The Fund may underperform other funds that do not seek to invest in companies based on expected societal impact outcomes. Although the Fund seeks to identify companies that it believes seek to address major social and environmental challenges, investors may differ in their views of what constitutes such challenges. As a result, the Fund may invest in companies that do not reflect the beliefs and values of any particular investor.

Active Investment Management Risk −The risk that, if the sub-adviser’s investment strategy does not perform as expected, the Fund could underperform its peers or lose money. The sub-adviser’s integration of ESG factors into its investment process may not work as intended. ESG factors are not the only factors considered and as a result, certain companies in which the Fund invests may not be considered an ESG company or have a high ESG rating.

Securities Lending Risk −The Fund may engage in securities lending. The Fund may lose money because the borrower of the loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Large Shareholder Transaction Risk −The Fund may experience adverse effects when certain large shareholders redeem or purchase large amounts of shares of the Fund. Such redemptions may cause the Fund to sell securities at times when it would not otherwise do so or borrow money (at a cost to the Fund), which may negatively impact the Fund's performance and liquidity. Similarly, large purchases 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. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs.

The Fund is subject to certain other risks. For more information regarding risks and investments, please see “Additional Information Regarding Investment Strategies and Risks” and "More Information About Risks" in the Fund’s statutory prospectus.
