@jayydee: easy spot-on solution.
FYI to others, it took me a second to understand the directions, so here’s my redux. It’s the exact same instruction with more explanation in case you are a newbie like me. Hope it helps.
Here was my case: I had created a page called “Staff” in my top menu, and attributed employees to it. I wanted people to be able to scroll down to “jen” “paul” and “mark” under staff and be able to click their name, but NOT be able to click “Staff”.
So:
To disable any parent item in WordPress 3.0 Menu:
(1) In the dashboard go to Appearances/Menus
(2) Go to Screen Options (top right) and activate Link Target.
(3) Go to Custom Links and insert any kind of link, and then Label it what you want your menu item to be called. In my case, this was “staff”.
(4) select the just created custom link. click on the dropdown link on the top right side of its box.
(5) delete the URL from the link target field.
(6) Drag and drop any pages/posts which you wish to attribute to it as you normally would. In my case, I placed “Jen” “paul” “mark” as its submenu items.
(6) done
