Question

I search in Internet but i didn't find a good documented way how to add to item from menu a number , my current menu is like

foreach( $items as $item ){

    if( strtolower($item->title)=='sample page' ){
        $item->title = $item->title.'(10)';
    }
}
return $items; } add_filter( 'wp_nav_menu_objects', 'wpa_filter_nav_menu_objects' );

You can target the location like this:

function wpa_filter_nav_menu_objects( $items, $args ){
    if( $args->theme_location === 'primary' ){
        foreach( $items as $item ){
            if( strtolower( $item->title ) === 'sample page' ){
                $item->title = $item->title . '(10)';
            }
        }
    }
    return $items;
}
add_filter( 'wp_nav_menu_objects', 'wpa_filter_nav_menu_objects', 10, 2 );

You can also try $args->menu_id if you use that input parameter.
