You can filter users in a user list menu/module with parameter SQL Custom Where, see here some examples: https://www.easy-profile.com/docs/69-sql-custom-where-list-and-module.html

You can simply exclude Super Users with this:

group_id NOT IN (8)

8 is default id for Super Users, to get other IDs see on Administration->User Manager->Groups

But where do i have to fill in this sql statement?

You can find this parameter in:
- User List menu item parameters under "List Layout" tab (see screenshot)
- User List (table) menu item parameters under "Table" tab
- User List module parameters
- User Map module parameters

hello support,

when I add this: group_id NOT IN (8) into CUSTOM SQL WHERE, the super users are still not filtered from the list.

why?

maybe in your Joomla installation the Super User usergroup have a different ID, anyway to check this we need your site details , to send these you can use the form below the reply i "Site Details" tab

ive supplied the details u asked for

Hi,
you have a User List module with SQL custom where empty, after you have a User List page (see screenshot)

in user list page you will se a empty form with search button because your configuration for menu item is this:
- enable search: Yes (so you see the form)
- Field to search: empty (so in form you will se only search button)
- Show All Members at the entrance of the page : No (so you not see users if you not click on search button)
