JavaScript/jQuery Panorama API

The Panorama widget is a full-screen widget that allows you to arrange items on a long horizontal canvas split into several views. Each view contains several items, and an end user navigates the views with the swipe gesture. The Panorama is often used as a navigation map on the first page of an application.

import Panorama from "devextreme/ui/panorama"

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 Panorama 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.
