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 may indicate higher transaction costs and may mean higher taxes if you are investing in a taxable account. These costs are not reflected in annual fund operating expenses or in the expense example, and can affect the fund's performance. During the most recent fiscal year, the fund’s portfolio turnover rate was 28% of the average value of its portfolio.

Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	This 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 and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the fund's operating expenses (including one year of capped expenses in each period) remain the same. Class C shares generally convert automatically to Class A shares after 8 years. The information presented in the Example for Class C reflects the conversion of Class C to Class A after 8 years. See “Class C Shares” in the “Choosing a Share Class” section of the prospectus for more information. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy [Heading]	rr_StrategyHeading	<span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;text-transform:uppercase;">Principal Investment Strategies</span>
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Main investments. Under normal circumstances, the fund invests at least 80% of net assets, plus the amount of any borrowings for investment purposes, in equity securities. The fund seeks to achieve its objective by employing an active investment strategy that invests primarily in the stocks comprising the S&P 500® Index, the fund’s benchmark index (the “benchmark”). The fund typically invests directly in common stocks, but may also invest in derivatives (see “Derivatives” subsection) that provide exposure to the stocks of the companies in the benchmark. To achieve exposure to the stocks of the companies in the benchmark, the fund may also invest, on a limited basis, in various sector and/or industry focused mutual funds and ETFs.Portfolio management, in its discretion will adjust, or “tilt,”upwards or downwards the fund’s levels of investments in benchmark sectors and industries relative to the benchmark sector/industry weights to reflect portfolio management’s ongoing assessments of such sectors and industries. This tilt strategy seeks to outperform the benchmark by identifying sector and industry preferences. The sector and industry preferences, which will be expressed as over, under or equal weight portfolio positions versus benchmark weights, are based on a fundamental research process that estimates the current and future earnings of each industry and sector. These earnings estimates are then valued using intrinsic valuation techniques that capitalize earnings estimates with discount rates that reflect risk and long-term growth potential. This analysis is performed on regular basis across all industries and sectors to determine portfolio preferences and the active weights. Portfolio management seeks to maintain industry and sector active weights for periods of generally 6 to 36 months. Sector active weights will generally be less than 5% over or underweight versus the benchmark, while industry active weights will generally be less than 10% over or under weight versus the benchmark. However, active weights can be larger or smaller and can be applied for shorter or longer periods than are generally targeted based on portfolio management’s assessment of market conditions and other macroeconomic circumstances.The over- and under-weight decisions will be made at the sector and industry level. Individual securities would maintain their proportionate weights within the benchmark sector or industry. When the sector/industry weight is raised, that additional weight for the sector/industry would be allocated to each security within the sector/industry based upon the weight of that security within the benchmark sector. There is no sampling or equal weighting of stocks in this process.From time to time, the fund may invest in securities that are not included in the benchmark and the fund’s portfolio may differ substantially from the benchmark because of the industry and sector tilts.Management process. Portfolio management will evaluate each sector and industry for its total return potential versus that of the benchmark. When making upwards or downwards adjustments to benchmark sector and industry positions, portfolio management will utilize a macro-minded (focused on broad market and industry factors) and intrinsic valuation oriented (using a disciplined process to evaluate deviations from estimates of intrinsic value) framework. This framework will include a fundamental assessment of the earnings outlook and observed valuation of each industry and sector. Assessments will utilize the macro views of the DWS Chief Investment Officer (CIO) Americas strategy team and key global DWS CIO View forecasts. Assessments will also take into consideration Environmental, Social and Governance (ESG) related risks and opportunities at the industry and sector level. Such CIO views and ESG risks and opportunities will influence portfolio management’s estimates of future earnings and cost of capital by industry and sector. Based on this fundamental assessment of the earnings outlook and observed valuation of each industry and sector, portfolio management identifies sector and industry preferences. Portfolio management does not expect to exclude or screen out individual securities from the benchmark universe based on ESG criteria except in extraordinary circumstances, when portfolio management’s assessment is that an individual company poses an extreme economic risk based on ESG factors.The portfolio management process uses estimates and forecasts and is subject to the uncertainty of such forward looking analysis and judgement. These estimates are reviewed by portfolio management on a regular basis (generally at least monthly) along with the industry and sector active weights.Portfolio management may use various industry standard third-party portfolio management and construction tools and other common portfolio management techniques to assess the sources of risk to the fund and to help control portfolio turnover, tax efficiency, and other factors.Derivatives. The fund may invest in derivatives, which are financial instruments whose performance is derived, at least in part, from the performance of an underlying asset, security or index. In particular, portfolio management may use futures contracts and options as a substitute for direct investment in a particular asset class or sector, to keep cash on hand to meet shareholder redemptions or for other needs while maintaining exposure to the stock market.The fund may also use other types of derivatives (i) for hedging purposes; (ii) for risk management; (iii) for non-hedging purposes to seek to enhance potential gains; or (iv) as a substitute for direct investment in a particular asset class or sector, or to keep cash on hand to meet shareholder redemptions.Securities lending. The fund may lend securities (up to one-third of total assets) to approved institutions, such as registered broker-dealers, pooled investment vehicles, banks and other financial institutions. In connection with such loans, the fund receives liquid collateral in an amount that is based on the type and value of the securities being lent, with riskier securities generally requiring higher levels of collateral.

Class ACIS | DWS Equity Sector Strategy Fund | Risk Lose Money [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	There are several risk factors that could hurt the fund’s performance, cause you to lose money or cause the fund’s performance to trail that of other investments.
Class ACIS | DWS Equity Sector Strategy Fund | Risk Not Insured Depository Institution [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	An investment in the fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency.
Class ACIS | DWS Equity Sector Strategy Fund | Risk Stock Market [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Stock market risk. When stock prices fall, you should expect the value of your investment to fall as well. Stock prices can be hurt by poor management on the part of the stock’s issuer, shrinking product demand and other business risks. These may affect single companies as well as groups of companies. The market as a whole may not favor the types of investments the fund makes, which could adversely affect a stock’s price, regardless of how well the company performs, or the fund’s ability to sell a stock at an attractive price. There is a chance that stock prices overall will decline because stock markets tend to move in cycles, with periods of rising and falling prices. Events in the US and global financial markets, including actions taken by the US Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility which could negatively affect performance. High market volatility may also result from significant shifts in momentum of one or more specific stocks due to unusual increases or decreases in trading activity. Momentum can change quickly, and securities subject to shifts in momentum may be more volatile than the market as a whole and returns on such securities may drop precipitously. To the extent that the fund invests in a particular geographic region, capitalization or sector, the fund’s performance may be affected by the general performance of that region, capitalization or sector.
Class ACIS | DWS Equity Sector Strategy Fund | Risk Strategy [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Strategy risk. The securities in the fund’s portfolio may decline in value. Portfolio management could be wrong in its analysis of sectors, industries, companies, economic trends, ESG risks and opportunities, the relative attractiveness of different sectors and industries, or other matters.
Class ACIS | DWS Equity Sector Strategy Fund | Risk Market Disruption [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Market disruption risk. Economies and financial markets throughout the world have become increasingly interconnected, which has increased the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. This includes reliance on global supply chains that are susceptible to disruptions resulting from, among other things, war and other armed conflicts, extreme weather events, and natural disasters. Such supply chain disruptions can lead to, and have led to, economic and market disruptions that have far-reaching effects on financial markets worldwide.The value of the fund’s investments may be negatively affected by adverse changes in overall economic or market conditions, such as the level of economic activity and productivity, unemployment and labor force participation rates, inflation or deflation (and expectations for inflation or deflation), interest rates, demand and supply for particular products or resources including labor, and debt levels and credit ratings, among other factors. Such adverse conditions may contribute to an overall economic contraction across entire economies or markets, which may negatively impact the profitability of issuers operating in those economies or markets. In addition, geopolitical and other globally interconnected occurrences, including war, terrorism, economic uncertainty or financial crises, contagion, trade disputes, government debt crises (including defaults or downgrades) or uncertainty about government debt payments, government shutdowns, public health crises, natural disasters, supply chain disruptions, climate change and related events or conditions, have led, and in the future may lead, to disruptions in the US and world economies and markets, which may increase financial market volatility and have significant adverse direct or indirect effects on the fund and its investments. Adverse market conditions or disruptions could cause the fund to lose money, experience significant redemptions, and encounter operational difficulties. Although multiple asset classes may be affected by adverse market conditions or a particular market disruption, the duration and effects may not be the same for all types of assets.Current military and other armed conflicts in various geographic regions, including those in Europe and the Middle East, can lead to, and have led to, economic and market disruptions, which may not be limited to the geographic region in which the conflict is occurring. Such conflicts can also result, and have resulted in some cases, in sanctions being levied by the United States, the European Union and/or other countries against countries or other actors involved in the conflict. In addition, such conflicts and related sanctions can adversely affect regional and global energy, commodities, financial and other markets and thus could affect the value of the fund's investments. The extent and duration of any military conflict, related sanctions and resulting economic and market disruptions are impossible to predict, but could be substantial.Other market disruption events include pandemic spread of viruses, such as the novel coronavirus known as COVID-19, which have caused significant uncertainty, market volatility, decreased economic and other activity, increased government activity, including economic stimulus measures, and supply chain disruptions. While COVID-19 is no longer considered to be a public health emergency, the fund and its investments may be adversely affected by lingering effects of this virus or future pandemic spread of viruses.In addition, markets are becoming increasingly susceptible to disruption events resulting from the use of new and emerging technologies to engage in cyber-attacks or to take over the Web sites and/or social media accounts of companies, governmental entities or public officials, or to otherwise pose as or impersonate such, which then may be used to disseminate false or misleading information that can cause volatility in financial markets or for the stock of a particular company, group of companies, industry or other class of assets.Adverse market conditions or particular market disruptions, such as those discussed above, may magnify the impact of each of the other risks described in this “MAIN RISKS” section and may increase volatility in one or more markets in which the fund invests leading to the potential for greater losses for the fund.
Class ACIS | DWS Equity Sector Strategy Fund | Risk Focus [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Focus risk. To the extent that the fund focuses its investments in particular industries, asset classes or sectors of the economy, any market price movements, regulatory or technological changes, or economic conditions affecting companies in those industries, asset classes or sectors may have a significant impact on the fund’s performance. The fund may become more focused in particular industries, asset classes or sectors of the economy as a result of changes in the valuation of the fund’s investments or fluctuations in the fund’s assets, and the fund is not required to reduce such exposures under these circumstances.
Class ACIS | DWS Equity Sector Strategy Fund | Risk Derivatives [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Derivatives risk. Derivatives involve risks different from, and possibly greater than, the risks associated with investing directly in securities and other more traditional investments. Risks associated with derivatives may include the risk that the derivative is not well correlated with the underlying asset, security or index to which it relates; the risk that derivatives may result in losses or missed opportunities; the risk that the fund will be unable to sell the derivative because of an illiquid secondary market; the risk that a counterparty is unwilling or unable to meet its obligation, which risk may be heightened in derivative transactions entered into “over-the-counter” (i.e., not on an exchange or contract market); and the risk that the derivative transaction could expose the fund to the effects of leverage, which could increase the fund's exposure to the market and magnify potential losses.
Class ACIS | DWS Equity Sector Strategy Fund | Risk Securities Lending [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Securities lending risk. Securities lending involves the risk that the fund may lose money because the borrower of the loaned securities fails to return the securities in a timely manner or at all. A delay in the recovery of loaned securities could interfere with the fund’s ability to vote proxies or settle transactions. Delayed settlement may limit the ability of the fund to reinvest the proceeds of a sale of securities or prevent the fund from selling securities at times and prices it considers desirable. The fund could also lose money in the event of a decline in the value of the collateral provided for the loaned securities, or a decline in the value of any investments made with cash collateral or even a loss of rights in the collateral should the borrower of the securities fail financially while holding the securities.
Class ACIS | DWS Equity Sector Strategy Fund | Risk Liquidity [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Liquidity risk. In certain situations, it may be difficult or impossible to sell an investment and/or the fund may sell certain investments at a price or time that is not advantageous in order to meet redemption requests or other cash needs. Unusual market conditions, such as an unusually high volume of redemptions or other similar conditions could increase liquidity risk for the fund.
Class ACIS | DWS Equity Sector Strategy Fund | Risk Counterparty [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Counterparty risk. A financial institution or other counterparty with whom the fund does business, or that underwrites, distributes or guarantees any investments or contracts that the fund owns or is otherwise exposed to, may decline in financial health and become unable to honor its commitments. This could cause losses for the fund or could delay the return or delivery of collateral or other assets to the fund.
Class ACIS | DWS Equity Sector Strategy Fund | Risk ETFs [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	ETF risk. Because ETFs trade on a securities exchange, their shares may trade at a premium or discount to their net asset value. An ETF is subject to the risks of the assets in which it invests as well as those of the investment strategy it follows. The fund may incur brokerage costs when it buys and sells shares of an ETF and also bears its proportionate share of the ETF’s fees and expenses, which are passed through to ETF shareholders.
Class ACIS | DWS Equity Sector Strategy Fund | Risk Pricing [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Pricing risk. If market conditions make it difficult to value some investments, the fund may value these investments using more subjective methods, such as fair value pricing. In such cases, the value determined for an investment could be different from the value realized upon such investment’s sale. As a result, you could pay more than the market value when buying fund shares or receive less than the market value when selling fund shares.
Class ACIS | DWS Equity Sector Strategy Fund | Risk Operational And Technology [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Operational and technology risk. Cyber-attacks, disruptions or failures that affect the fund’s service providers or counterparties, issuers of securities held by the fund, or other market participants may adversely affect the fund and its shareholders, including by causing losses for the fund or impairing fund operations. For example, the fund’s or its service providers’ assets or sensitive or confidential information may be misappropriated, data may be corrupted and operations may be disrupted (e.g., cyber-attacks, operational failures or broader disruptions may cause the release of private shareholder information or confidential fund information, interfere with the processing of shareholder transactions, impact the ability to calculate the fund’s net asset value and impede trading). Market events and disruptions also may trigger a volume of transactions that overloads current information technology and communication systems and processes, impacting the ability to conduct the fund’s operations.While the fund and its service providers may establish business continuity and other plans and processes that seek to address the possibility of and fallout from cyber-attacks, disruptions or failures, there are inherent limitations in such plans and systems, including that they do not apply to third parties, such as fund counterparties, issuers of securities held by the fund or other market participants, as well as the possibility that certain risks have not been identified or that unknown threats may emerge in the future and there is no assurance that such plans and processes will be effective. Among other situations, disruptions (for example, pandemics or health crises) that cause prolonged periods of remote work or significant employee absences at the fund’s service providers could impact the ability to conduct the fund’s operations. In addition, the fund cannot directly control any cybersecurity plans and systems put in place by its service providers, fund counterparties, issuers of securities held by the fund or other market participants.
