| 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 fiscal year ended July 31, 2024, the Fund’s portfolio turnover rate was 51% of the average value of its portfolio. | ||

| Strategy [Heading] | rr_StrategyHeading | <span style="font-family:Arial Narrow;font-size:11pt;font-weight:bold;">PRINCIPAL INVESTMENT STRATEGY. </span> | ||
| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | Under normal circumstances, the Fund seeks to achieve its investment objective by investing primarily in common stocks of issuers located in the United States. Wellington Management Company LLP (“Wellington Management”), the Fund’s sub-adviser, chooses the Fund’s investments using fundamental research to seek to identify high-quality companies demonstrating a commitment to dividends and shareholders and improving or sustainable operating characteristics. Wellington Management’s investment process focuses on companies that it believes are undervalued market leaders, industries with improving supply/demand trends, and companies that it believes are out-of-favor with less downside risk than the overall market. The Fund may invest in a broad range of market capitalizations, but tends to focus on large capitalization companies with market capitalizations similar to those of companies in the Russell 1000 Value Index. The Fund’s portfolio seeks to be broadly diversified by company and industry. Based on market or economic conditions, the Fund may, through its normal stock selection process, focus in one or more sectors of the market | ||

| Performance Narrative [Text Block] | rr_PerformanceNarrativeTextBlock | The performance information shown below provides some indications of the risks of investing in this Fund. Effective as of October 13, 2023, the Fund acquired all eligible assets and liabilities of Hartford Quality Value Fund (the “Predecessor Fund”), a mutual fund series of The Hartford Mutual Funds II, Inc., and adopted the accounting and performance history of the Predecessor Fund (the “Conversion”). The Fund has the same investment objective, strategies, policies and portfolio management team as the Predecessor Fund. The bar chart shows how the performance of the Fund’s shares (represented through October 13, 2023 by the performance of the Predecessor Fund’s Class F shares) has varied from year to year for the past ten calendar years. The table shows the Fund’s average annual total returns (represented through October 13, 2023 by the average annual total returns of the Predecessor Fund’s Class F shares) for the past one year, five years and ten years. The performance of the Predecessor Fund shown below through October 13, 2023 has not been adjusted to reflect the lower fees and expenses that are incurred by the Fund. The Predecessor Fund was a mutual fund, and the average annual total returns as shown below are based on NAV per share, and are not based on market prices for an ETF share as traded on an exchange. Predecessor Fund performance is based on the performance of Class F shares through October 13, 2023 and includes the Predecessor Fund’s performance when the Predecessor Fund pursued a different investment objective and principal investment strategy prior to November 1, 2017. The bar chart and performance information provide an indication of the historical risk of an investment in the Fund by showing: ●how the Predecessor Fund’s performance changed from year to year over ten years; and ●how the Predecessor Fund’s average annual returns for one, five and ten years compare to those of a broad-based securities market index. You may obtain updated performance information on the website at hartfordfunds.com. Past performance, as shown for the Predecessor Fund through October 13, 2023 and the Fund, before and after taxes, does not necessarily indicate how the Fund will perform in the future. | ||

| Risk [Text Block] | rr_RiskTextBlock | 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. | ||
| Hartford Quality Value ETF | Risk Not Insured Depository Institution [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | 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. | ||
| Hartford Quality Value ETF | Market Risk [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | 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, or as a result of other events such as geopolitical events, natural disasters, or widespread pandemics (such as COVID-19) or other adverse public health developments. | ||
| Hartford Quality Value ETF | Equity Risk [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | 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. | ||
| Hartford Quality Value ETF | Large Cap Securities Risk [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | Large Cap Securities Risk – The securities of large market capitalization companies may underperform other segments of the market because such companies may be less responsive to competitive challenges and opportunities and may be unable to attain high growth rates during periods of economic expansion. | ||
| Hartford Quality Value ETF | Value Investing Style Risk [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | Value Investing Style Risk – Using a value investing style to select investments involves special risks. Overlooked or otherwise undervalued securities entail a significant risk of never attaining their potential value or may even be overpriced. Also, the value investing style may over time go in and out of favor. At times when the value investing style is out of favor, the Fund may underperform other equity funds that use different investing styles. “Value” securities can be undervalued by the market for long periods of time. | ||
| Hartford Quality Value ETF | Dividend Risk [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | Dividend Risk – Income provided by the Fund may be affected by changes in the dividend policies of the companies in which the Fund invests and the capital resources available for such payments at such companies. At times, the performance of dividend-paying companies may lag the performance of other companies or the broader market as a whole. In addition, the dividend payments of the companies in which the Fund invests may vary over time, and there is no guarantee that a company will pay a dividend at all. | ||
| Hartford Quality Value ETF | Active Investment Management Risk [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | 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. | ||
| Hartford Quality Value ETF | Sector Risk [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | Sector Risk – To the extent the Fund invests more heavily in a particular sector or sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, from the broader market. | ||
| Hartford Quality Value ETF | Market Price Risk [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | Market Price Risk – The net asset value (“NAV”) of the Fund’s shares and the value of your investment may fluctuate. The market prices of the Fund’s shares will generally fluctuate in accordance with changes in NAV and changes in the intraday value of the Fund’s holdings, as well as the relative supply of and demand for the shares on the Fund’s listing exchange. Although it is expected that the Fund’s shares will remain listed on the exchange, disruptions to creations and redemptions, the existence of market volatility or lack of an active trading market for the shares (including through a trading halt), as well as other factors, may result in the shares trading significantly above (at a premium to) or below (at a discount to) the Fund’s NAV or the intraday value of the Fund’s holdings. In addition, because liquidity in certain underlying portfolio securities may fluctuate over time, shares of the Fund may, at times, trade at a larger than normal premium or discount to NAV. In addition, to the extent certain of the Fund’s portfolio securities are trading on days or at times the Fund’s shares are not trading, bid-ask spreads and the resulting premium or discount to the NAV of the Fund’s shares may widen. During such periods, you may be unable to sell your shares or may incur significant losses if you sell your shares. There are various methods by which investors can purchase and sell shares and various types of orders that may be placed. Investors should consult their financial intermediary before purchasing or selling shares of the Fund. Neither the investment manager nor the Fund’s sub-adviser can predict whether the Fund’s shares will trade below, at or above their NAV. Price differences may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for the Fund’s shares will be closely related to, but not identical to, the same forces influencing the prices of the Fund’s holdings trading individually or in the aggregate at any point in time. In addition, unlike many ETFs, the Fund is not an index fund. The Fund is actively managed and does not seek to replicate the performance of a specified index. There can be no assurance as to whether and/or to what extent the Fund’s shares will trade at premiums or discounts to NAV or to the intraday value of the Fund’s holdings. | ||
| Hartford Quality Value ETF | Authorized Participant Concentration Risk [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | Authorized Participant Concentration Risk – Only an authorized participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of intermediaries that act as authorized participants on an agency basis (i.e., on behalf of other market participants), and none of these authorized participants are or will be obligated to engage in creation or redemption transactions. To the extent that these intermediaries exit the business or are unable to or choose not to proceed with creation and/or redemption orders with respect to the Fund and no other authorized participant is able to step forward to create or redeem, Fund shares may trade at a premium or discount to NAV and possibly face trading halts and/or delisting. | ||
| Hartford Quality Value ETF | Valuation Risk [Member] | ||||
| Risk Return Abstract | rr_RiskReturnAbstract | |||
| Risk [Text Block] | rr_RiskTextBlock | Valuation Risk – The sale price the Fund could receive for a security may differ from the Fund’s valuation of the security, particularly for securities that trade in low volume or volatile markets or that are valued using a fair value methodology. In addition, the value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares. | ||
