| RACWI US ETF | Mid-Capitalization Companies Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Mid-Capitalization Companies Risk. Investing in securities of mid-capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies’ securities may be more volatile and less liquid than those of more established companies. Often mid-capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. |
| RACWI US ETF | Micro- And Small- Capitalization Companies Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Micro- and Small-Capitalization Companies Risk. Investing in securities of micro-cap and small-cap companies generally involves greater risks than investing in large-capitalization companies. Micro- and small-cap companies may have limited product lines, markets or financial resources or may depend on the expertise of a few people and may be subject to more abrupt or erratic market movements than securities of larger companies or market indices in general. Many micro and small capitalization companies may be in the early stages of development. Since equity securities of smaller companies may lack sufficient market liquidity and may not be regularly traded, it may be difficult or impossible to sell securities at an advantageous time or a desirable price.

| Risk [Text Block] | Investment Risk. When you sell your Shares, they could be worth less than what you paid for them. The Fund could lose money due to short-term market movements and over longer periods during market downturns. Securities may decline in value due to factors affecting securities markets generally or particular asset classes or industries represented in the markets. The value of a security may decline due to general market conditions, economic trends or events that are not specifically related to the issuer of the security. Geopolitical and other risks, including war, terrorism, trade disputes, political or economic dysfunction within some nations, public health crises, and environmental disasters such as earthquakes, fire, and floods, may add to instability in world economies and volatility in markets generally. Changes in trade policies and international trade agreements could affect the economies of many countries in unpredictable ways. The value of a security may also decline due to factors that affect a particular industry or group of industries. During a general downturn in the securities markets, multiple asset classes may be negatively affected. Therefore, you may lose money by investing in the Fund. |
| RACWI US ETF | Equity Investing Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Equity Investing Risk. An investment in the Fund involves risks similar to those of investing in any fund holding equity securities, such as market fluctuations, changes in interest rates and perceived trends in stock prices. The values of equity securities could decline generally or could underperform other investments. In addition, securities may decline in value due to factors affecting a specific issuer, market or securities markets generally. |
| RACWI US ETF | Sector Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Sector Risk. To the extent the Fund invests more heavily in particular sectors of the economy, its performance will be especially sensitive to developments that significantly affect those sectors. The Fund may invest a significant portion of its assets in the following sectors and, therefore, the performance of the Fund could be negatively impacted by events affecting each of these sectors. •Information Technology Sector Risk. Market or economic factors impacting technology companies and companies that rely heavily on technological advances could have a significant effect on the value of the Fund’s investments. The value of stocks of technology companies and companies that rely heavily on technology is particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Stocks of technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Technology companies are heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely affect profitability.

| Risk [Text Block] | ETF Risks. •Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. •Premium-Discount Risk. The Shares may trade above or below their net asset value (“NAV”). The market prices of Shares will generally fluctuate in accordance with changes in NAV as well as the relative supply of, and demand for, Shares on The Nasdaq Stock Market LLC (the “Exchange”) or other securities exchanges. The trading price of Shares may deviate significantly from NAV during periods of market volatility or limited trading activity in Shares. In addition, you may incur the cost of the “spread,” that is, any difference between the bid price and the ask price of the Shares. •Cost of Trading Risk. Investors buying or selling Shares in the secondary market will pay brokerage commissions or other charges imposed by brokers as determined by that broker. Brokerage commissions are often a fixed amount and may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of Shares. •Trading Risk. Although the Shares are listed on the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of its underlying portfolio holdings, which can be less liquid than Shares, potentially causing the market price of Shares to deviate from its NAV. The spread varies over time for Shares of the Fund based on the Fund’s trading volume and market liquidity and is generally lower if the Fund has high trading volume and market liquidity, and higher if the Fund has little trading volume and market liquidity (which is often the case for funds that are newly launched or small in size).

|
| RACWI US ETF | Concentration Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Concentration Risk. The Fund may be susceptible to an increased risk of loss, including losses due to adverse occurrences affecting the Fund more than the market as a whole, to the extent that the Fund’s investments are concentrated in the securities of a particular issuer or issuers, market, industry, group of industries, sector, or asset class.
|
| RACWI US ETF | Passive Investment Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Passive Investment Risk. The Fund is not actively managed, and the Sub-Adviser will not sell shares of an equity security due to current or projected underperformance of a security, industry or sector, unless that security is removed from the Index, sold in connection with a rebalancing of the Index, or sold to comply with the Fund’s investment limitations (for example, to maintain the Fund’s tax status). Maintaining investments regardless of market conditions or the performance of individual investments could cause the Fund’s return to be lower than if the Fund employed an active strategy.
|
| RACWI US ETF | Tracking Error Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Tracking Error Risk. As with all index funds, the performance of the Fund and its Index may differ from each other for a variety of reasons. For example, the Fund incurs operating expenses and portfolio transaction costs not incurred by the Index. In addition, the Fund may not be fully invested in the securities of the Index at all times or may hold securities not included in the Index. The Fund’s use of a representative sampling strategy to track the Index may produce greater tracking error than if the Fund employed a full replication strategy.
|
| RACWI US ETF | Annual Rebalance Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Annual Rebalance Risk. The Index’s components are reconstituted annually. As a result, the Index’s exposure to one or more securities may be affected by significant price movements promptly following the annual reconstitution. Such lags between Index rebalancing may result in significant performance swings relative to the broader equity markets.
|
| RACWI US ETF | Large-Capitalization Companies Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Large-Capitalization Companies Risk. Large-capitalization companies may trail the returns of the overall stock market. Large-capitalization stocks tend to go through cycles of doing better - or worse - than the stock market in general. These periods have, in the past, lasted for as long as several years.
|
| RACWI US ETF | Risk Of Investing In The U.S Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Risk of Investing in the U.S. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.
|
| RACWI US ETF | Sampling Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Sampling Risk. To the extent the Fund uses a representative sampling approach, it will hold a smaller number of securities than are in the Index. As a result, an adverse development respecting a security held by the Fund could result in a greater decline in NAV than would be the case if the Fund held all of the securities in the Index. Conversely, a positive development relating to a security in the Index that is not held by the Fund could cause the Fund to underperform the Index. To the extent the assets in the Fund are smaller, these risks will be greater.
|
| RACWI US ETF | Index Calculation Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Index Calculation Risk. The Index relies on various sources of information to assess the criteria of issuers included in the Index, including fundamental information that may be based on assumptions and estimates. Neither the Fund, the Adviser, the Sub-Adviser nor the index administrator can offer assurances that the Index’s calculation methodology or sources of information will provide a correct valuation of securities, nor can they guarantee the availability or timeliness of the production of the Index.
|
| RACWI US ETF | New Fund Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | New Fund Risk. The Fund is a recently organized management investment company with limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision. There can be no assurance that the Fund will grow to or maintain an economically viable size. |
| RACWI US ETF | Risk Lose Money [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | An investor may lose money by investing in the Fund. |
| RACWI US ETF | Risk Not Insured Depository Institution [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | An investment in the Fund is not a bank deposit and is not insured or guaranteed by the FDIC or any government agency. |
| RACWI US ETF | Risk Nondiversified Status [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Non-Diversification Risk. Because the Fund is non-diversified, it may be more sensitive to economic, business, political or other changes affecting individual issuers or investments than a diversified fund, which may result in greater fluctuation in the value of the Shares and greater risk of loss.
|
| Research Affiliates Deletions ETF | Mid-Capitalization Companies Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Mid-Capitalization Companies Risk. Investing in securities of mid-capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies’ securities may be more volatile and less liquid than those of more established companies. Often mid-capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions. |
| Research Affiliates Deletions ETF | Micro- And Small- Capitalization Companies Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Micro- and Small-Capitalization Companies Risk. Investing in securities of micro- and small-capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. Micro- and small-capitalization companies often have less predictable earnings, more limited product lines, markets, distribution channels and financial resources, and the management of such companies may be dependent upon one or a few people. The securities of micro- and small-capitalization companies may be more volatile and less liquid than mid-capitalization and large-capitalization companies. Micro-capitalization companies may be more volatile than small-capitalization companies.
|
| Research Affiliates Deletions ETF | Value Investing Risk Member | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Value Investing Risk. Securities issued by companies that may be perceived as undervalued may be appropriately valued. Value securities may fail to appreciate for long periods of time or may never realize their full potential value. In addition, the Fund’s ability to realize any benefits of investing in value securities may depend on the Fund’s ability to stay invested until the market’s perception of such securities change. Value securities have generally performed better than non-value securities during periods of economic recovery (although there is no assurance that they will continue to do so). Value securities may go in and out of favor over time.

Technology companies are heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely affect profitability. •Consumer Discretionary Sector Risk. The consumer discretionary sector may be affected by changes in domestic and international economies, exchange and interest rates, competition, consumers’ disposable income and consumer preferences, social trends and marketing campaigns. •Healthcare Sector Risk. Companies in the healthcare sector, including drug related companies, may be heavily dependent on clinical trials with uncertain outcomes and decisions made by the governments and regulatory authorities. Further, these companies are dependent on patent protection, and the expiration of patents may adversely affect the profitability of the companies. Additionally, the profitability of some healthcare and life sciences companies may be dependent on a relatively limited number of products, and their products can become obsolete due to sector innovation, changes in technologies or other market developments.
