jQuery UI Draggable handle Option

Last Updated : 29 Jan, 2022

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 Draggable handle Option. This option restricts dragging from starting unless the mousedown occurs on the specified element(s). Only elements that descend from the draggable element are permitted. The default value of this option is false.

Syntax:

The handle option takes a Selector or Element type value and the syntax is as follows.

$( ".selector" ).draggable({ handle: "h2" });

Get the handle option

var handle = $( ".selector" ).draggable( "option", "handle" );

Set the handle option

$( ".selector" ).draggable( "option", "handle", "h2" );
