How some user can't see specific user that i choose?



i want create group that it's include Teacher and Students.
All of them are in one group(Teacher and Students).
i want when one Student send a file , just can see their Teacher in list and can't see other classmates in list(that they are in same group).
but Owncloud panel show all classmate(in same group).
please tell how config that Students just see Teacher who are in their group.



this is currently not really possible.

To achieve what you're looking for you need to create one group for each student and add each teacher to these groups.

That's probably not that practical


thank you sir,
do you have any suggestion for do this work with other app(for sharing like owncloud)?
