jQuery UI consists of GUI widgets, visual effects, and themes implemented using the jQuery JavaScript library. jQuery UI is great for building UI interfaces for the webpages. It can be used to build highly interactive web applications or can be used to add widgets easily.
The jQuery UI Selectable selecting event is used to trigger during the select operation, on each element added to the selection.
Syntax:
Initialize the Selectable widget with the selecting callback function.
$( ".selector" ).selectable({
selecting: function( event, ui ) {}
});
Bind an event listener to the Selectable selecting event.
$( ".selector" ).on(
"selectableselecting",
function( event, ui ) {}
);Parameters:
- event: This event is triggered when selecting the items.
- ui: It is a jQuery object that is used for the current selectable item that is being selected.
- selecting: It is of the element type. It is the item that is being selected.
CDN Link: First, add jQuery UI scripts needed for your project.

<script src=”https://code.jquery.com/jquery-1.12.4.js”></script>
