5. METHODS

.multiselect(‘destroy’)

This method is used to destroy the plugin on the given element – meaning unbinding the plugin.

.multiselect(‘refresh’)

This method is used to refresh the checked checkboxes based on the currently selected options within the select. Click ‘Select some options’ so select some of the options (meaning added the selected attribute to some of the options). Then click refresh. The plugin will update the checkboxes accordingly.

.multiselect(‘rebuild’)

Rebuilds the whole dropdown menu. All selected options will remain selected (if still existent!).

.multiselect(‘select’, value, triggerOnChange)

Selects an option by its value. Works also using an array of values. If triggerOnChange is set to true, the onChange event is triggered.

.multiselect(‘deselect’, value)

Deselect an option by its value. Works also using an array of values. If triggerOnChange is set to true, the onChange event is triggered.

.multiselect(‘dataprovider’, data)

Provides data for building the select’s options the following way:

.multiselect(‘setOptions’, options)

Used to change configuration after initializing the multiselect. This may be useful in combination with .multiselect(‘rebuild’).

.multiselect(‘disable’)

Disable both the underlying select and the dropdown button.

.multiselect(‘enable’)
