jQWidgets is a JavaScript framework for making web-based applications for PC and mobile devices. It is a very powerful and optimized framework, platform-independent, and widely supported. The jqxComboBox is used to represent a jQuery combobox widget that contains an input field with auto-complete functionality and a list of selectable items displayed in a drop-down.
The enableItem() method is used to enable an item. It accepts a single parameter item of object/string type and it does not return any value.
The following fields can also be used for the enabled item:
- label
- value
- disabled
- checked
- hasThreeStates
- html
- group
Syntax:
$('selector').jqxComboBox('enableItem', 'Item' );
