Just to let you know as it is not updated Walid has put a Joomla 1.5 version of the Quick Jump Menu on the site. However the problem reported still persists (the level-0 menu items still do not appear. Only the menu-items that are sub-menus will work) Naturally you can get round this by putting all your menu items as level-1 but IMO this is a flaw.

otherwise this module works ok.
