How do I create a space navigation bar like this one?

Hi all. Looking for a little guidance. One of the apps we recently purchased has a beautiful sub-menu navigation bar on their pages that I'm looking to create. Anyone have any knowledge of how it was created? Thanks in advance.

I have never seen anything like this for Confluence. I guess the question I have is what do you want this menu bar to do within the page? Is it simply like a table of contents that is arranged horizontally or something more elaborate?
