The accordion effect works only for some groups of extra fields, not for all. In categories with three groups seems to work ok, but some groups more categories are not displayed.
It seems that only despligan if you click on order in the group titles.
If I start with 1, 2 etc. unfold all but the last.
If you have deployed any group, I can only display the first, the others do not work.
Can you help me fix it?
