I ve been doing some approaches with differing view and edit access
for many user groups or acls but by the end of day
separate collections, separate flys and separate forms linked properly with each other,
were simplest and most effective solution.
Limiting the access in builder would require adding id or name of group or ACL that is in other instance of Joomla,
no idea how to solve that easier...? Or in config on joomlas backed?
Second issue what was necessary and universal,
was to connect viewing records ACL with authors groups
for example if user is in group A,
and saves the record all users for group A have also access to that record,
but
when user is is many groups there was a problem,
should we define actual context...?
but when trying to allow users to edit only owns groups records
and have other records view only made
mess like hell
Thinking about data access
you mean adding ACLs to columns in table?
hmmm that would simplyfy a lot...
PS thx for filters in menu items!
