I am trying to put a tab in my custom compact header for my music player. I am using this on a wall mounted tablet where the sidebar will be hidden so I would like it to be up top in the header.
I have tried the following, but it does not auto adjust to the height in portrait views. Is there an easy way to make it always fill the vertical height.
I am doing the exact same thing with a node red dashboard and with the same configuration (panel: true) it fills all the page.
Have you tried to use https://REDACTED/ outside HA to check whether it looks the way you want?
