jQuery UI Sortable remove Event

Last Updated : 20 Jan, 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.

The jQuery UI Sortable remove Event is used to trigger when an item from a connected sortable list has been dropped into another list and the former is the event target source.

Syntax: We need to initialize the sortable widget with the remove callback function

$( ".selector" ).sortable({

remove : function( event, ui ) {}

});

Bind an event listener to the sort remove event:

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

Parameters: These are the following parameters that are accepted.

event: This event is triggered when an item is removed from the sort list.
ui: This parameter is of type object with below-given options.
- helper: This parameter is the jQuery object representing the sorted helper.
- item: This parameter is the jQuery object that represents the current dragged item.
- offset: This parameter is the current absolute position of the helper object which is represented as { top, left }.
- position: This parameter is the current position of the helper object which is represented as { top, left }.
- originalPosition: This parameter is the original position of the helper object which is represented as { top, left }.
- placeholder: This parameter is the element that is used as a placeholder. This is of type jQuery object.
