Designing a site for a fairly large non-profit.I have ACL usergroups set up and working correctly, so that users can edit specific sections.How do I set up menus that can only be viewable by specific usergroups? The site spans six different sub-brands, and each has different confidential information.

Since the deafult offers public, registared, and special...and k2 offers groups only editing and publishing constraints
You may have to do an override that will check first for the user, then for the k2 user group and use logic to allow your k2 users to only see what you want them to.
Ive seen other code here that checks for the k2 user group..if i find it ill post it

Found the code
in a category override wrap what you want to hide from non registared users as in the attached text file
Play around with the code and set it for the user group you want to have access

See attached. Where am I going wrong? I'm trying to make a module that shows up when someone from usergroup
"SecureMember" logs in. Right now when logged out, it still shows the module.
