JQWidgets jqxTree expandItem() Method - Coding

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 expandItem() method is used to expand a jqxTree widget item by passing an element as parameter. It accepts a single parameter item of object type and does not return any value.

Syntax:

$('Selector').jqxTree('expandItem', item);
