Introduction: 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 jqxDropDownList widget is a jQuery drop-down list that contains a list of selectable items displayed in the drop-down list.

The selectionRenderer property is used to set or return the callback function that is called when the selected item is rendered in the jqxDropDownList’s content area. It accepts Boolean type value and its default value is null.

Syntax:

Set the selectionRenderer property.

$('selector').jqxDropDownList({ selectionRenderer: Number });

 

Return the selectionRenderer property.

var selectionRenderer = $('selector').jqxDropDownList('selectionRenderer');
