## Selectable Widget version added: 1.0

Description: Use the mouse to select elements, individually or in a group.

## QuickNavExamples

The jQuery UI Selectable plugin allows for elements to be selected by dragging a box (sometimes called a lasso) with the mouse over the elements. Elements can also be selected via click or drag while holding the ctrl/meta key, allowing for multiple (non-contiguous) selections.

### 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

### appendToType: Selector

Default: `"body"`
Which element the selection helper (the lasso) should be appended to.
Code examples:

Initialize the selectable with the appendTo option specified:

`$(` `".selector"` `).selectable({ appendTo:` `"#someElem"` `});`

Get or set the appendTo option, after initialization:

`// getter` `var` `appendTo = $(` `".selector"` `).selectable(` `"option"``,` `"appendTo"` `);` `// setter` `$(` `".selector"` `).selectable(` `"option"``,` `"appendTo"``,` `"#someElem"` `);`

### autoRefreshType: Boolean

Default: `true`
This determines whether to refresh (recalculate) the position and size of each selectee at the beginning of each select operation. If you have many items, you may want to set this to false and call the `refresh()` method manually.
Code examples:

Initialize the selectable with the autoRefresh option specified:

`$(` `".selector"` `).selectable({ autoRefresh:` `false` `});`

Get or set the autoRefresh option, after initialization:

`// getter` `var` `autoRefresh = $(` `".selector"` `).selectable(` `"option"``,` `"autoRefresh"` `);` `// setter` `$(` `".selector"` `).selectable(` `"option"``,` `"autoRefresh"``,` `false` `);`

### cancelType: Selector

Default: `"input,textarea,button,select,option"`
Prevents selecting if you start on elements matching the selector.
Code examples:

Initialize the selectable with the cancel option specified:

`$(` `".selector"` `).selectable({ cancel: a,.cancel });`

Get or set the cancel option, after initialization:

`// getter` `var` `cancel = $(` `".selector"` `).selectable(` `"option"``,` `"cancel"` `);` `// setter` `$(` `".selector"` `).selectable(` `"option"``,` `"cancel"``, a,.cancel );`

### delayType: Integer

Default: `0`
Time in milliseconds to define when the selecting should start. This helps prevent unwanted selections when clicking on an element.
Code examples:

Initialize the selectable with the delay option specified:

`$(` `".selector"` `).selectable({ delay: 150 });`

Get or set the delay option, after initialization:

`// getter` `var` `delay = $(` `".selector"` `).selectable(` `"option"``,` `"delay"` `);` `// setter` `$(` `".selector"` `).selectable(` `"option"``,` `"delay"``, 150 );`

### disabledType: Boolean

Default: `false`
Disables the selectable if set to `true`.
Code examples:

Initialize the selectable with the disabled option specified:

`$(` `".selector"` `).selectable({ disabled:` `true` `});`

Get or set the disabled option, after initialization:

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

### distanceType: Number

Default: `0`
Tolerance, in pixels, for when selecting should start. If specified, selecting will not start until the mouse has been dragged beyond the specified distance.
Code examples:

Initialize the selectable with the distance option specified:

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

Get or set the distance option, after initialization:

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

### filterType: Selector

Default: `"*"`
The matching child elements will be made selectees (able to be selected).
Code examples:

Initialize the selectable with the filter option specified:

`$(` `".selector"` `).selectable({ filter: li });`

Get or set the filter option, after initialization:

`// getter` `var` `filter = $(` `".selector"` `).selectable(` `"option"``,` `"filter"` `);` `// setter` `$(` `".selector"` `).selectable(` `"option"``,` `"filter"``, li );`

### toleranceType: String

Default: `"touch"`
Specifies which mode to use for testing whether the lasso should select an item. Possible values:

- `"fit"`: Lasso overlaps the item entirely.
- `"touch"`: Lasso overlaps the item by any amount.

Code examples:

Initialize the selectable with the tolerance option specified:

`$(` `".selector"` `).selectable({ tolerance:` `"fit"` `});`

Get or set the tolerance option, after initialization:

`// getter` `var` `tolerance = $(` `".selector"` `).selectable(` `"option"``,` `"tolerance"` `);` `// setter` `$(` `".selector"` `).selectable(` `"option"``,` `"tolerance"``,` `"fit"` `);`
