I found a Confluence page on our internal Confluence, where the creator is no longer with our company, and it had a menu that changes what is displayed on the page.
I found it to be very intuitive, and easy to use, but I have no idea how it's created, as I don't have Edit access to that page.
See example below, so the page has some top text, and then a menu where you can select different topics, and even subtopics. But I cannot figure out what this is called, can someone point me in the right direction?
