Hello community :-)
a few days ago I stumbled over a Confluence homepage that included a second navigation bar (including a menu) as you can see in the picture included.

I tried to reproduce something similar in my instance, but didn't find it - neither in the Jira administration (look and feel) nor in the Confluence administration (look and feel).
Does anyone know how to insert an additional layer in the horizontal navigation?
Thanks in advance for your help,
Sebastian
