 * Description : A combobox which also has an intermediate state.
 *               This is akin to the intermediate state in a checkbox and
 *               needed when a single combobox controls more than one item,
 *               which are manually set to different states.
 *               The intermediate state is indicated by appending an extra item
 *               with a user specified text (default is "Various"). Whenever an
 *               other item is set, this special state is removed from the list
 *               so it can never be selected explicitly.
