   * - caption: caption for the menu item (when not provided the global menuCaptionId is used).
   * - controller: controller (page) for this item.
   * - link: link for this page (overrides reverse controller name route, but can also be used in absence of controller).
   * - right: right the user must have to view this page, and thus the menu item (controller default right is also checked).
   * - items: array with sub-menu items.
   * @param string $type  View type (empty = default; true = current).
   * @return array  Nested array with only viewable items, or items with sub-items. Key = caption. value = array with:
   * - link: link for the item.
   * - items: sub items (always present; might be empty).
