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.
In this article, we will learn how to use the jQuery UI Droppable greedy Option. This option set the parent droppable not to receive the element. The default value of this option is “false”.
Syntax:
The greedy option takes a boolean type value and the syntax is as follows:
$( ".selector" ).draggable({ appendTo: "body" });-
Get the greedy option:
var appendTo = $( ".selector" ).draggable( "option", "appendTo" );
-
Set the greedy option:
$( ".selector" ).draggable( "option", "appendTo", "body" );
