Hidden objects are different.

Put an item on the Parent Page - like page numbers. 

Then go to the  pages in your document.

Then you can use 

It's a way to hide the Parent Pages without having to add blank pages etc. 

For specific pages or spreads.

You're right Eugene, I had noticed but by now I had posted...
However, the phrase "the parent item may be hidden on a lower layer or the parent items may be hidden." it's a bit ambiguous...

If you can elaborate I will submit a request to update it. 
Thanks
