Group Selection Horizontal

[phipz]

On the groups card (where you select the currently active player), the different group buttons are listed vertically.
With Readme Example 21 one can change the width of the buttons.

Would it be possible to get guidance/an example of how to arrange the group buttons horizontally?

I am aiming to have a slim horizontal player selection on top of my music dashboard.
Thank you very much for all your absolutely brilliant work.

Not sure how to do this. Leaving it as an open discussion topic here in case someone else knows.
