Hi Yves
Finaly I did it like this:
I created group for every class and every single teacher.
than I created Access Level for every single subject.
Than I created Category for every single subject in matukio with same ACL group 1:1.
What solved my issue but:
As there are more than 300 subject I decided to create "matukio categories" via database import.
So I created entries for XX_categories and xx_assets columns.
I can see all created categories in category list but If I want to create new event - in the list I can see only categories, which was created via admin panel - I can not see categories created by CSV imports to database.
Do you have a clue what I missed? Or where can be problem (Create 300 entries take some time
)
Thank you a lot for your support.
