/* params
 * - link_on_section
 * - css = use suckerfish menu
 * - type = vert|horiz
 * - id = menu ID (mandatory)
 * - translate = y|n , n means no option translation (default y)
 * - menu_cookie=y|n (default y) n, it will automatically open the submenu the url is in
 * - sectionLevel: displays from this level only
 * - toLevel : displays to this level only
 * - drilldown ??
 * - bootstrap : navbar|basic (equates to horiz or vert in old menus)
 * - setSelected=y|n (default=y) processes all menu items to show currently selected item, also sets open states, sectionLevel, toLevel etc
 * 								so menu_cookie, sectionLevel and toLevel will be ignored if this is set to n
