My question is, are ACLs always hierarchal, where each lower level (greater access) can see every level above?
For example, in a school, let’s say the administrators have the most access. An administrator can view all articles and modules, including all that the teachers can see and all that the students can see; plus, Admin can also see all sorts of admin stuff that other levels cannot see.
Teachers, however, can only see teacher’s items and students items; students can only see students items.
This is how I understand ACL.
However, is there another dimension in Joomla? Is there someway to make all the above possible, plus make it a particular student can see articles that are only meant for her; or, a “horizontal” access level?
I’m picturing a scenario where each member of a group, with identical ACL clearance, can, in some instances, see particular articles that are only theirs (even though those with higher ACL clearance can also see these same articles).
Is this possible?
