Methods

Events

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

autoRefresh 

Type: 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.

cancel 

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

delay 

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

disabled 

Type: Boolean
Default: false
Disables the selectable if set to true.

distance 

Type: 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.

filter 

Type: Selector
Default: "*"
The matching child elements will be made selectees (able to be selected).

tolerance 

Type: 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.
