Bootstrap Panels Auto Close others on open of 1

Is it possible to set all otther panels to auto close when opening a specific one? My panels are inside repeat so it is not a case of just targeting 1 or 2 panels.

I think you mean bootstrap 4 cards as panels is bootstrap 3 terminology.

And what you seek is the accordion under cards that we just added to be nicely working with the bootstrap 4 collapse - it’s all in ver 1.3.0
