jQuery UI Draggable

The jQuery UI Draggable plugin makes selected elements draggable by mouse.

Draggable elements gets a class of ui-draggable. During drag the element also gets a class of ui-draggable-dragging. If you want not just drag, but drag-and-drop, see the jQuery UI Droppable plugin, which provides a drop target for draggables.

All callbacks (start, stop, drag) receive two arguments: The original browser event and a prepared ui object, view below for a documentation of this object (if you name your second argument 'ui'):

ui.helper - the jQuery object representing the helper that's being dragged
ui.position - current position of the helper as { top, left } object, relative to the offset element
ui.offset - current absolute position of the helper as { top, left } object, relative to page

Dependencies

UI Core

Initialize a draggable with default options.

$("#draggable").draggable();

addClasses

Type:

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() init on many hundreds of elements.

```
$('.selector').draggable({ addClasses: false });
```
Get or set the addClasses option, after init.

The element passed to or selected by the appendTo option will be used as the draggable helper's container during dragging. By default, the helper is appended to the same container as the draggable.
Code examples
Initialize a draggable with the appendTo option specified.
```
$('.selector').draggable({ appendTo: 'body' });
```
Get or set the appendTo option, after init.

The jQuery UI Draggable 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 ui.draggable.css stylesheet that can be modified. These classes are highlighed in bold below.

Sample markup with jQuery UI CSS Framework classes

Note: This is a sample of markup generated by the draggable plugin, not markup you should use to create a draggable. The only markup needed for that is <div></div>.
