If you need add class in custom menu, use next code:

add_filter('nav_menu_css_class','arg_menu_classes',110,3);

function arg_menu_classes($classes, $item, $args) {
    if($args->menu == 'FooterMenu') { // name need menu
        $classes[] = 'col-6 col-sm-6'; // add classes
    }
    return $classes;
