React Dialogs and Notifications - Overview
DevExtreme Dialog and Notification React components include several popup components used to interact with an app. This demo shows two of them: Popup and Popover. Learn more about DevExtreme React components.
To give you the ability to edit code on the fly, the demo uses SystemJS. For this reason, launching the demo takes some time. We strongly recommend that you do not use this approach in real projects.
Was this demo helpful?
Feel free to share demo-related thoughts here.
