jQWidgets is a JavaScript framework for making web-based applications for PC and mobile devices. It is a very powerful, optimized, platform-independent, and widely supported framework. The jqxTree represents a jQuery widget that is used to display a hierarchical collection of items. To display the collection of items, we can populate from ‘UL’ or by using its ‘source’ property.

The dragStart property is used to set the callback function that is called when the item dragging starts. It accepts the Function type value and its default value is null.

Syntax:

$('selector').jqxTree({ dragStart: Function });
