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 checkItem() method is used to check a tree widget item. It accepts two parameter, the first one is item of object type and the second is state of boolean type. It does not return any value.

Syntax:

$('Selector').jqxTree('checkItem', item, state);
