Last Updated : 07 Feb, 2022

jQuery UI is a web-based technology and consists of various GUI widgets, visual effects, and themes. These features can be implemented using the jQuery JavaScript Library. jQuery UI is the best tool for building UI interfaces for the webpages. It can also be used to build highly interactive web applications or can be used to add widgets easily.

In this article, we will be using the jQuery UI Droppable create Event to trigger when the droppable is created.

Syntax:

We need to initialize the droppable widget with the create a callback function

$( ".selector" ).droppable({

create : function( event, ui ) {}

});

Bind an event listener to the drop create event:

$( ".selector" ).on( "dropcreate ", function( event, ui ) {} );

Parameters: These are the following parameters that are accepted.

event: This event is triggered when the sort creates an item.
ui: This parameter is of type object. The ui object is empty but included for consistency with other events.
