Galleries inside an accordion

Hallo.

We have palced some galleries inside accordions.
This doesn’t work properly.
When opening an accordion tab, the images won’t expand the way they shoud.
Is there any possible css workaround to fix this?
Right now expanding the images is only viable via clicking the tag filters above.
(“BITTE FILTER W?HLEN” = “PLEASE SELECT FILTER”)

Kind regards…!
