In a SharePoint Online list, generate a three-screen app that manages the list.
You can Create an app using PowerApps from the command bar of any SharePoint Online custom list. Apps generated through this flow show up as views within the new SharePoint modern list experience. This allows you to leverage PowerApps to build custom, mobile-optimized views of your existing lists and share them with your co-workers. Because PowerApps is a cross-platform service, you can run the apps you generate across all of your devices including Windows, iOS, Android, and the web browser.
For information about what kinds of SharePoint data PowerApps supports, see Known issues.
If you're unfamiliar with PowerApps, see Introduction to PowerApps.
Open a custom list in SharePoint Online, select PowerApps on the command bar, and then select Create an app.
In the panel that appears, enter your app name, and then select Create.
PowerApps Studio for web opens a new browser tab and creates a default app automatically based on the list’s schema and data.
Select Open from the original SharePoint tab.
Note: You might need to refresh the browser window (for example, by pressing F5) before the app will open.
The app opens in a separate browser tab.
