React CheckBox API

The CheckBox is a small box, which when selected by the end user, shows that a particular feature has been enabled or a specific option has been chosen.

import CheckBox from "devextreme-react/check-box"

Type: CheckBoxTypes.default

DevExtreme widgets are integrated with many popular libraries and frameworks. See the Installation section (for JavaScript libraries) or the Prerequisites and Installation section (for ASP.NET MVC framework) to find details on setting up DevExtreme with a particular library or framework.

The following code shows how to create the CheckBox widget using every supported library and framework. For more details on working with widgets in these libraries and frameworks, see the Widget Basics topic for jQuery, Angular, AngularJS, Knockout or ASP.NET MVC.
