Losing superfish menu item after logging out from administration panel I have a superfish menu as my nav menu bar. I customised it and added some pages for each menu item. 

When I log out of the administration panel, as a general user I can only see the first menu item, all other menu items are gone. 

[edit below]

Right, found out that the problem was because my other three menu items are all link to '.../add/node'. Superfish will not show empty links on the menu bar. However, I actually don't want some of the items link to anywhere as they all have submenu items. I want the link to remain empty so that the user can click on the submenu item. How can I achieve this?
When an item in a menu tree is unavailable because of a lack of permissions, the entire tree below that item will disappear.

You should probably restructure your menu to use placeholders. Have a look at the Special menu items module.
