I am new to Moodle and all the things i've tested i liked a lot, but i have a question. I want to create course categories, ones open to all users, others only visible to a certain group or cohorts of users. For example: usergroupA and usergroupB can see al courses in category Open Courses. usergroupA can see Categroy groupA_Courses but how to make this category invisible to usergroupB. I mean when a user from groupB collapses al available courses the only one the user can see (categories which are on top level of courses) are the open categories and the categories assigned to his/her group, but cannot see categories from group A. Till now the user can see al categories but cannot enrol on others group courses but i want to hide the categories which are not for his/her group to avoid which other courses are given to other groups. I tried with cohorts, hiding categroies,... How can i do that ??
Thanks in advance.
