Thank you for the fast reply. But: your plugin is able to filter the user meta. It it really powerful! It is just not able to add the search parameter cause “custom field” is a required value.
Example: one of the user meta fields is “um_food”. If I enter “Pizza” in the search field, I get all users who like Pizza. It works already. But if I try to add a custom field to the search query, “um_food” does not appear and therefore I can not create a drop down list where users can select Pizza, Burger, etc.
Best regards,
Peter
