I'm confused about what to do with the menu items whose sole function is 'to be parent' i.e. no content attached to them. One way I wanted to solve this is to set the path to
<front> for those items. But then subitems just won't fly out anymore.
Similarly, if I set the path of a parent item to the node that belongs to a child item, the parent just totally disappears out of the menu, leave alone that there would be a child to pop out of.
