Adding Navigation Within A Page

Hi,

I'm trying to do something I was able to do in Squarespace 7.0. Right now I have Squarespace 7.1 and I can't do it anymore. Essentially it's putting the different pages within the folder in navigation menu inside a page (see attached). Makes it easier for people to navigate and see the different pages instead of going back to the nav bar.

Is there any way I can achieve this? 

I'd highly appreciate the help!

What about doing it manually with anchor links?

Or are you wanting a full "second on page/hovering" nav?
