jQuery UI – Mouse Interactions: Resizing Elements

When “resizing” is applied to an element, the element is given a handle and can be visually resized using a mouse. You’ve already seen this ability indirectly with the dialog widget, which is a resizable widget. Table 9-6 lists all available $.reslzable() methods.

Given that resizing is such a basic operation, you might be surprised at how many options are available, as shown in Table 9-7. Like the other mouse interactions in this chapter, the default utility fits many needs, but it still allows for many flexible options.

In the following example, you create a resizable widget with an animation, a minimum width and height of 300 pixels, ghosting, and a red box helper outline. The filled-in text uses the “bacon ipsum” text generator. Lorem ipsum is nice but bacon ipsum is tastier.

<!DOCTYPE html>






rel=”stylesheet” />

<script src=”http://code.jquery.com/jquery-1.7.1.js”></script>

<script src=”js/jquery-ui-1.8.13.custom.min.js”></script>

<style type=”text/css”>

.ui-resizable-helper {

border: 1px solid red;


#resize_me {

border: 1px solid black;

overflow : hidden;



<script type=”text/javascript”>



animate: true,

ghost : true,

helper: “ui-resizable-helper”,

minWidth: 300,

minHeight : 300






<div id=”resize_me” class=”ui-widget-content”>

<h2 class=”ui-widget-header”>Pork and Stuff</h2>
