# 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

- ### ghost

  Type:
    Boolean

- ### grid

  Type:
    Array
  Default:
    false

  Snaps the resizing element to a grid, every x and y pixels. Array values: [x, y]

  #### Code examples

  Initialize a resizable with the `grid` option specified.

        								$( ".selector" ).resizable({ grid: [50, 50] });

- ### handles

  Type:
    String, Object
  Default:
    'e, s, se'

  If specified as a string, should be a comma-split list of any of the following: 'n, e, s, w, ne, se, sw, nw, all'. The necessary handles will be auto-generated by the plugin.

  If specified as an object, the following keys are supported: { n, e, s, w, ne, se, sw, nw }. The value of any specified should be a jQuery selector matching the child element of the resizable to use as that handle. If the handle is not a child of the resizable, you can pass in the DOMElement or a valid jQuery object directly.

  #### Code examples

  Initialize a resizable with the `handles` option specified.

        								$( ".selector" ).resizable({ handles: 'n, e, s, w' });

  Get or set the `handles` option, after init.

- ### helper

  Type:
    String
  Default:
    false

  This is the css class that will be added to a proxy element to outline the resize during the drag of the resize handle. Once the resize is complete, the original element is sized.

  #### Code examples

  Initialize a resizable with the `helper` option specified.

        								$( ".selector" ).resizable({ helper: 'ui-state-highlight' });

  Get or set the `helper` option, after init.

## 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>.
