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.
The jQuery UI Sortable beforeStop Event is used to trigger when sorting stops, but when the placeholder/helper is still available.
Syntax:
We need to initialize the sortable widget with the beforeStop callback function
$( ".selector" ).sortable({
beforeStop : function( event, ui ) {}
});-
Bind an event listener to the sortbeforestop event:
$( ".selector" ).on( "sortbeforestop", function( event, ui ) {} );
