jQuery UI resizable documentation

## Resizable Widgetversion 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.

### 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.

## Options

### alsoResizeType: Selector or jQuery or Element

Default: `false`
One or more elements to resize synchronously with the resizable element.

### aspectRatioType: Boolean or Number

Default: `false`
Whether the element should be constrained to a specific aspect ratio.
Multiple types supported:

- Boolean: When set to `true`, the element will maintain its original aspect ratio.

### distanceType: Number

Default: `1`
Tolerance, in pixels, for when resizing should start. If specified, resizing will not start until after mouse is moved beyond distance. This can help prevent unintended resizing when clicking on an element.

`$(` `".selector"` `).resizable({ distance: 30 });`

Get or set the distance option, after initialization:

`// getter` `var` `distance = $(` `".selector"` `).resizable(` `"option"``,` `"distance"` `);` `// setter` `$(` `".selector"` `).resizable(` `"option"``,` `"distance"``, 30 );`

Get or set the ghost option, after initialization:

`// getter` `var` `ghost = $(` `".selector"` `).resizable(` `"option"``,` `"ghost"` `);` `// setter` `$(` `".selector"` `).resizable(` `"option"``,` `"ghost"``,` `true` `);`

### gridType: Array

Default: `false`
Snaps the resizing element to a grid, every x and y pixels. Array values: `[ x, y ]`.
Code examples:

Initialize the resizable with the grid option specified:

`$(` `".selector"` `).resizable({ grid: [ 20, 10 ] });`

Get or set the grid option, after initialization:

`// getter` `var` `grid = $(` `".selector"` `).resizable(` `"option"``,` `"grid"` `);` `// setter` `$(` `".selector"` `).resizable(` `"option"``,` `"grid"``, [ 20, 10 ] );`

### 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.

Code examples:

Initialize the resizable with the handles option specified:

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

Get or set the handles option, after initialization:

`// getter` `var` `handles = $(` `".selector"` `).resizable(` `"option"``,` `"handles"` `);` `// setter` `$(` `".selector"` `).resizable(` `"option"``,` `"handles"``,` `"n, e, s, w"` `);`

Get or set the helper option, after initialization:

`// getter` `var` `helper = $(` `".selector"` `).resizable(` `"option"``,` `"helper"` `);` `// setter` `$(` `".selector"` `).resizable(` `"option"``,` `"helper"``,` `"resizable-helper"` `);`
