jQuery UI Resizable

Overview

The jQuery UI Resizable plugin makes selected elements resizable (meaning they have draggable resize handles). You can specify one or more handles as well as min and max width and height.

All callbacks (start,stop,resize) receive two arguments: The original browser event and a prepared ui object. The ui object has the following fields:

  • ui.helper - a jQuery object containing the helper element
  • ui.originalPosition - {top, left} before resizing started
  • ui.originalSize - {width, height} before resizing started
  • ui.position - {top, left} current position
  • ui.size - {width, height} current size

Dependencies

  • UI Core
  • UI Widget
  • UI Mouse

Example

A simple jQuery UI Resizable.

$("#resizable").resizable();

<!DOCTYPE html>
<html>
<head>
  <link href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/themes/base/jquery-ui.css" rel="stylesheet" type="text/css"/>
  <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js"></script>
  <script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/jquery-ui.min.js"></script>
  <style type="text/css">
    #resizable { width: 100px; height: 100px; background: silver; }
  </style>
  <script>
  $(document).ready(function() {
    $("#resizable").resizable();
  });
  </script>
</head>
<body style="font-size:62.5%;">
  
<div id="resizable"></div>

</body>
</html>

Theming

The jQuery UI Resizable plugin uses the jQuery UI CSS Framework to style its look and feel, including colors and background textures. We recommend using the ThemeRoller tool to create and download custom themes that are easy to build and maintain.

If a deeper level of customization is needed, there are widget-specific classes referenced within the jquery.ui.resizable.css stylesheet that can be modified. These classes are highlighed in bold below.

Sample markup with jQuery UI CSS Framework classes

<div class="ui-resizable">
   <div style="-moz-user-select: none;" unselectable="on" class="ui-resizable-handle ui-resizable-e"></div>
   <div style="-moz-user-select: none;" unselectable="on" class="ui-resizable-handle ui-resizable-s"></div>
   <div unselectable="on" style="z-index: 1001; -moz-user-select: none;" class="ui-resizable-handle ui-resizable-se ui-icon ui-icon-gripsmall-diagonal-se"></div>
</div>

Note: This is a sample of markup generated by the resizable plugin, not markup you should use to create a resizable. The only markup needed for that is <div></div>.
