I have my posts/pages default set to unblocked, and then I have blocked a couple of pages via the custom field block=true. These pages are all in one menu, and I do not want to show excerpts. Instead, I want the menu to only appear to users who have logged in. I've noticed that the menu items (and sub-items) display in the menu for non-logged in users (i.e. the public). Is there a way to do this? Or does a blocked page appear in a menu anyway?
