## Resizable Widget version added: 1.0

Description: Change the size of an element using the mouse.

## QuickNavExamples

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.

### Dependencies

- UI Core
- Widget Factory
- Mouse Interaction

### Additional Notes:

- This widget requires some functional CSS, otherwise it won't work. If you build a custom theme, use the widget's specific CSS file as a starting point.

### handlesType: String or Object

Default: `"e, s, se"`
Which handles can be used for resizing.
Multiple types supported:

- String: A comma delimited 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.
- 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.

  Note: When generating your own handles, each handle must have the `ui-resizable-handle` class, as well as the appropriate `ui-resizable-{direction}` class, .e.g., `ui-resizable-s`.

Code examples:

Initialize the resizable with the `handles` option specified:

1 |
    $( ".selector" ).resizable({ handles: "n, e, s, w" });

    $( ".selector" ).resizable({ helper: "resizable-helper" });

Get or set the `helper` option, after initialization:
