Remove “Other Roles” drop down, roles in Users page and everywhere else?

“Other Roles Access” add-on included into Pro version has another purpose while contains the same “other roles” word. I answered on your questions at the Pro version related forum that it’s not a bug, but a feature.

In order to fulfill the task from this topic title use custom filters:

add_filter('ure_show_additional_capabilities_section', 'ure_show_additional_capabilities_section');
add_filter('ure_bulk_grant_roles',  'ure_show_additional_capabilities_section');

 
function ure_show_additional_capabilities_section($show) {

    $user = wp_get_current_user();
    if (in_array('user-manager', $user->roles)) {
        $show = false;
    }

    return $show;
}
