jQuery Box API

The Box widget allows you to arrange various elements within it. Separate and adaptive, the Box widget acts as a building block for the layout.

import Box from "devextreme/ui/box"

Type:

Object

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 Box 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.
