Please expand on your requirement.
Are you referring to user management pages in the dashboard? to pages owned by users in a group? anything else?

Hey John

We are building a HR website which contains the functionality to manage staff per business.

So for example, say Company X was using the system. When they login they only see and manage staff under the Company X group. Don't wish then to see any other company or users within another group.

If you are considering managing staff as c5 users in the dashboard or viewing c5 user profiles, I don't think you can restrict that to users in a group without writing some custom code to override the dashboard pages and profile single pages.

If you want to set up lists of staff/users shown on front end pages and filtered by group, that is entirely possible. Several addons can help you set up such lists, including my own Uber List addon (for c5.6.x).

If you want to set up CV pages for individual staff, whether as users or as form results, you can restrict access of those pages to user groups with c5 permissions.

You may also find some of the real estate addons could be adapted to this purpose.

Thanks for that. Thats what I thought. Will check out your add-ons! ;-)

Thanks!
