Users Dropdown from Advanced Filter

Hi Everybody,
i’m wondering if is it possible to edit the users dropdown in the advanced filter (assigned user id).
I’ve to hide some users from the filter even if they are active!
Thank you for your kindness, and happy new year.

Instead of editing the Dropdown, you could simply play with Roles and Security Settings so that some Users are invisible.

If you go into admin/User management, it behaves just like a normal module, and you can add specific users to Security Groups.

Then you need to set up the rest of your Security Scheme, sometimes this an be complicated to begin with. Try to start by following this guide, then adapt to your needs.
