It’s quite simple, if you want to remove the “resume” tab or job_alert subnav for employer for ex., in your function.php (or in an included file in it):
add_filter('um_user_profile_tabs', 'um_job_dashboard_user_remove_tab', 1000 );
function um_job_dashboard_user_remove_tab( $tabs ) {
if ( current_user_can('employer')) {
unset( $tabs['resume_manager'] );
unset( $tabs['job_manager']['subnav']['job_alerts'] );
}
}
Be careful when removing a “default” tab or surbnav, you’ll have to define a visible tab as default.
