This code has been modified from it's original source to support select2 groupings, which the original did not support.
Plugin that makes select2 multiple select sortable out of the box.
Usage:
// init select2 sortable
$(select2multiselect).select2Sortable();
// destroy select2 sortable
$(select2multiselect).select2Sortable('destroy');
// manually trigger the sorting
$(select2multiselect).select2SortableOrder();
// custom options
$(select2multiselect).select2Sortable({
bindOrder: 'formSubmit' // or `sortableStop`,
sortableOptions: {
// please refer to jQuery UI sortable API (http://api.jqueryui.com/sortable/)
}
});
