Hi @AnnMarieW, @KoalifiedEnough, thanks for the replies!
Giving it a unique id does make it so that everytime you click reload, all accordion items close. That could be achieved also by setting value=None in the accordion.
However, (maybe I dind’t explain myself correctly 
), I want to achieve quite the opposite: to keep whatever the user has opened and closed as is. In my video, the first two tries work like that, but for some reason on the last one for example, you can see I close and open the B item and then hit reload, and the B item automatically closes (I would want for it to stay opened like in the first try).
I know this is supposed to be done with the value of accordion but in my case it’s a bit more complex because I’m trying to apply it to something similar to the file explorer tree (which I saw you contributed to btw @AnnMarieW , thanks 
). Maybe it’s not possible to achieve what I want, I just found it weird that it’s almost there by default.
