is it possible to deactivate categories for groups or categories in general (groups, events, photos, videos)? Because i think for a fresh forum categories are not necessary in the beginning since it will end up creating lots of empty lists.
I would like to activate them again later, when people started opening their groups and when we get a feeling for the categories that would fit these groups
that by design the categories for groups, events, photos, and videos are mandatory. it need too much effort if you want disable for all of it. especially at sharebox section.
and here for remove the categories listing at groups page:
1. override groups.index.php, by copying from /components/com_community/templates/default/ to /templates/yoo_everest/html/com_community/
2. edit it, and take out this code
