## Draggable Widget version added: 1.0

Description: Allow elements to be moved using the mouse.

## QuickNavExamples

Make the selected elements draggable by mouse. If you want not just drag, but drag & drop, see the jQuery UI Droppable plugin, which provides a drop target for draggables.

## Options

### addClassesType: Boolean

Default: `true`
If set to `false`, will prevent the `ui-draggable` class from being added. This may be desired as a performance optimization when calling `.draggable()` on hundreds of elements.
Code examples:

Initialize the draggable with the addClasses option specified:

`$(` `".selector"` `).draggable({ addClasses:` `false` `});`

Get or set the addClasses option, after initialization:

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

### appendToType: jQuery or Element or Selector or String

Default: `"parent"`
Which element the draggable helper should be appended to while dragging.
Multiple types supported:

- jQuery: A jQuery object containing the element to append the helper to.
- Element: The element to append the helper to.
- Selector: A selector specifying which element to append the helper to.
- String: The string `"parent"` will cause the helper to be a sibling of the draggable.

Code examples:

Initialize the draggable with the appendTo option specified:

`$(` `".selector"` `).draggable({ appendTo:` `"body"` `});`

Get or set the appendTo option, after initialization:

`// getter` `var` `appendTo = $(` `".selector"` `).draggable(` `"option"``,` `"appendTo"` `);` `// setter` `$(` `".selector"` `).draggable(` `"option"``,` `"appendTo"``,` `"body"` `);`

### axisType: String

Default: `false`
Constrains dragging to either the horizontal (x) or vertical (y) axis. Possible values: `"x"`, `"y"`.
Code examples:

Initialize the draggable with the axis option specified:

`$(` `".selector"` `).draggable({ axis:` `"x"` `});`

Get or set the axis option, after initialization:

`// getter` `var` `axis = $(` `".selector"` `).draggable(` `"option"``,` `"axis"` `);` `// setter` `$(` `".selector"` `).draggable(` `"option"``,` `"axis"``,` `"x"` `);`

### cancelType: Selector

Default: `"input,textarea,button,select,option"`
Prevents dragging from starting on specified elements.
Code examples:

Initialize the draggable with the cancel option specified:

`$(` `".selector"` `).draggable({ cancel:` `".title"` `});`

Get or set the cancel option, after initialization:

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

### connectToSortableType: Selector

Default: `false`
Allows the draggable to be dropped onto the specified sortables. If this option is used, a draggable can be dropped onto a sortable list and then becomes part of it. Note: The `helper` option must be set to `"clone"` in order to work flawlessly. Requires the jQuery UI Sortable plugin to be included.
Code examples:

Initialize the draggable with the connectToSortable option specified:

`$(` `".selector"` `).draggable({ connectToSortable:` `"#my-sortable"` `});`

Get or set the connectToSortable option, after initialization:

`// getter` `var` `connectToSortable = $(` `".selector"` `).draggable(` `"option"``,` `"connectToSortable"` `);` `// setter` `$(` `".selector"` `).draggable(` `"option"``,` `"connectToSortable"``,` `"#my-sortable"` `);`

### containmentType: Selector or Element or String or Array

Default: `false`
Constrains dragging to within the bounds of the specified element or region.
Multiple types supported:

- Selector: The draggable element will be contained to the bounding box of the first element found by the selector. If no element is found, no containment will be set.
- Element: The draggable element will be contained to the bounding box of this element.
- String: Possible values: `"parent"`, `"document"`, `"window"`.
- Array: An array defining a bounding box in the form `[ x1, y1, x2, y2 ]`.

`$(` `".selector"` `).draggable({ delay: 300 });`

Get or set the delay option, after initialization:

`// getter` `var` `delay = $(` `".selector"` `).draggable(` `"option"``,` `"delay"` `);` `// setter` `$(` `".selector"` `).draggable(` `"option"``,` `"delay"``, 300 );`

### disabledType: Boolean

`$(` `".selector"` `).draggable({ scope:` `"tasks"` `});`

Get or set the scope option, after initialization:
