Hello,
No picture because it is a sequence of steps
I do not think this is possible today, so this is a new suggestion
today
Step 1
I select the format field wordpress post: video
Step 2
it appears the group fields: video
It’ works with me but problem New authors do not find (or do not understand)
tomorrow !!
>>> Only in acf fields
Step 1
first select the required input field acf post_format (taxonomy): video
Step 2
it appears the group fields: video
Regards
