You could build this with the Field Group ( [LINK] ) module, which will allow you to group your content fields into horizontal tabs, vertical tabs, accordions and more. By default, groups with only empty fields will be hidden, i.e., they will not display in the "menu". While this would not create separate pages, your use of the word in quotes makes me think this would be an acceptable answer. There is a decent tutorial at [this video] .

When the field group module is installed and enabled, you should be able to add groups. This video explains it very well [this video] At 1m57 it starts where you are [this video] If you don't see the add group, something went wrong when installing the module and you should re-install it.

If the whole point of this is to be able to add wrappers around fields, an alternate option would be to use the field group [LINK] module. Here is a video tutorial [this video] on it.
