Plugin for accepting multiple strings from a specified list. In the var_list configuration, specify value_list as a list of strings. If there is more than one operator specified for this plugin, then they are displayed on a menu.

The value argument passed to QueryBuilder.appendNew() must be an array with two elements: [ operator_name, value_list ], where value_list is an array of strings.

If you specify autocomplete.containerClassName in the var_list configuration, this CSS class will be added to the container generated by the autocomplete plugin.
