## Sortable Widgetversion added: 1.0

Description: Reorder elements in a list or grid using the mouse.

## QuickNavExamples

The jQuery UI Sortable plugin makes selected elements sortable by dragging with the mouse.

Note: In order to sort table rows, the `tbody` must be made sortable, not the `table`.

### Dependencies

- UI Core
- Widget Factory
- Mouse Interaction

## Options

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

Default: `"parent"`
Defines where the helper that moves with the mouse is being appended to during the drag (for example, to resolve overlap/zIndex issues).
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 sortable item.

Code examples:

Initialize the sortable with the `appendTo` option specified:

1

    $( ".selector" ).sortable({ appendTo: document.body });

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

1
2
3
4
5

    // gettervar appendTo = $( ".selector" ).sortable( "option", "appendTo" ); // setter$( ".selector" ).sortable( "option", "appendTo", document.body );

### axisType: String

Default: `false`
If defined, the items can be dragged only horizontally or vertically. Possible values: `"x"`, `"y"`.
Code examples:

Initialize the sortable with the `axis` option specified:

1

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

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

1
2
3
4
5

    // gettervar axis = $( ".selector" ).sortable( "option", "axis" ); // setter$( ".selector" ).sortable( "option", "axis", "x" );

### cancelType: Selector

Default: `":input,button"`
Prevents sorting if you start on elements matching the selector.
Code examples:

Initialize the sortable with the `cancel` option specified:

1

    $( ".selector" ).sortable({ cancel: "a,button" });

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

1
2
3
4
5

    // gettervar cancel = $( ".selector" ).sortable( "option", "cancel" ); // setter$( ".selector" ).sortable( "option", "cancel", "a,button" );

### connectWithType: Selector

Default: `false`
A selector of other sortable elements that the items from this list should be connected to. This is a one-way relationship, if you want the items to be connected in both directions, the `connectWith` option must be set on both sortable elements.
Code examples:

Initialize the sortable with the `connectWith` option specified:

1

    $( ".selector" ).sortable({ connectWith: "#shopping-cart" });

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

1

### containmentType: Element or Selector or String

Default: `false`

Defines a bounding box that the sortable items are contrained to while dragging.

Note: The element specified for containment must have a calculated width and height (though it need not be explicit). For example, if you have `float: left` sortable children and specify `containment: "parent"` be sure to have `float: left` on the sortable/parent container as well or it will have `height: 0`, causing undefined behavior.

Multiple types supported:

- Element: An element to use as the container.
- Selector: A selector specifying an element to use as the container.
- String: A string identifying an element to use as the container. Possible values: `"parent"`, `"document"`, `"window"`.

1

    $( ".selector" ).sortable({ containment: "parent" });

## Methods

### cancel()Returns: jQuery (plugin only)

Cancels a change in the current sortable and reverts it to the state prior to when the current sort was started. Useful in the stop and receive callback functions.

- This method does not accept any arguments.

Code examples:

Invoke the cancel method:

1

    $( ".selector" ).sortable( "cancel" );

### destroy()Returns: jQuery (plugin only)

Removes the sortable functionality completely. This will return the element back to its pre-init state.

- This method does not accept any arguments.

Code examples:

Invoke the destroy method:

1

    $( ".selector" ).sortable( "destroy" );

### disable()Returns: jQuery (plugin only)

Disables the sortable.

- This method does not accept any arguments.

Code examples:

Invoke the disable method:

1

    $( ".selector" ).sortable( "disable" );

### enable()Returns: jQuery (plugin only)

Enables the sortable.

- This method does not accept any arguments.

Code examples:

Invoke the enable method:

1

    $( ".selector" ).sortable( "enable" );

### option( optionName )Returns: Object

Gets the value currently associated with the specified `optionName`.

- optionName
  Type: String
  The name of the option to get.

Code examples:

Invoke the method:

1

    var isDisabled = $( ".selector" ).sortable( "option", "disabled" );

### option()Returns: PlainObject

Gets an object containing key/value pairs representing the current sortable options hash.

- This signature does not accept any arguments.

Code examples:

Invoke the method:

1

    var options = $( ".selector" ).sortable( "option" );

### option( optionName, value )Returns: jQuery (plugin only)

Sets the value of the sortable option associated with the specified `optionName`.

- optionName
  Type: String
  The name of the option to set.
- value
  Type: Object
  A value to set for the option.

Code examples:

Invoke the method:

1

    $( ".selector" ).sortable( "option", "disabled", true );

### option( options )Returns: jQuery (plugin only)

Sets one or more options for the sortable.

- options
  Type: Object
  A map of option-value pairs to set.

Code examples:

Invoke the method:

1

    $( ".selector" ).sortable( "option", { disabled: true } );

### refresh()Returns: jQuery (plugin only)

Refresh the sortable items. Triggers the reloading of all sortable items, causing new items to be recognized.

- This method does not accept any arguments.

Code examples:

Invoke the refresh method:

1

    $( ".selector" ).sortable( "refresh" );

### refreshPositions()Returns: jQuery (plugin only)

Refresh the cached positions of the sortable items. Calling this method refreshes the cached item positions of all sortables.

- This method does not accept any arguments.

Code examples:

Invoke the refreshPositions method:

1

    $( ".selector" ).sortable( "refreshPositions" );

### serialize( options )Returns: String

Serializes the sortable's item `id`s into a form/ajax submittable string. Calling this method produces a hash that can be appended to any url to easily submit a new item order back to the server.

It works by default by looking at the `id` of each item in the format `"setname_number"`, and it spits out a hash like `"setname[]=number&setname[]=number"`.

Note: If serialize returns an empty string, make sure the `id` attributes include an underscore. They must be in the form: `"set_number"` For example, a 3 element list with `id` attributes `"foo_1"`, `"foo_5"`, `"foo_2"` will serialize to `"foo[]=1&foo[]=5&foo[]=2"`. You can use an underscore, equal sign or hyphen to separate the set and number. For example `"foo=1"`, `"foo-1"`, and `"foo_1"` all serialize to `"foo[]=1"`.

- options
  Type: Object
  Options to customize the serialization.
  - key (default: `the part of the attribute in front of the separator`)
    Type: String
    Replaces `part1[]` with the specified value.

    Type: String
    The name of the attribute to use for the values.
  - expression (default: `/(.+)[-=_](.+)/`)
    Type: RegExp
    A regular expression used to split the attribute value into key and value parts.

Code examples:

Invoke the serialize method:

1

    var sorted = $( ".selector" ).sortable( "serialize", { key: "sort" } );

### toArray( options )Returns: Array

Serializes the sortable's item id's into an array of string.

- options
