I created three groups (staff, partner & dealer) under same parent - Registered and Viewing to associated groups (staff -> staff, partner -> partner, dealer -> dealer). <br />
When I wrote a content and giving access to "staff" but Public could see that post also the others group could. <br />
So I would like to make each groups having each viewing content access. How to give them permission in Joomla 3.x.x? <br /><br />
P.S: Sorry for my bad English.
