jQuery UI is a web-based technology and consists of GUI widgets, visual effects, and themes 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.
The jQuery UI Droppable deactivate Event is used to trigger when an accepted draggable stop dragging.

We need to initialize the Droppable widget with the deactivate a callback function:
$( ".selector" ).droppable({
deactivate: function( event, ui ) {}
});-
Bind an event listener to the dropdeactivate an event:
$( ".selector" ).on( "dropdeactivate ", function( event, ui ) {} );
