此插件提供过滤器，以按元值管理菜单项：

function custom_menu_item_visibility( $visible, $item ){ 
    if( isset( $item->roles ) ){ 
        $user_id = get_current_user_id(); 
        $user_meta = get_user_meta( $user_id, \'your-meta-key\', true ); 
        if ( /* your condition */ ){ 
            $visible = true; 
        } else { 
            $visible = false; 
        } 
    } 
    return $visible; 
} 
add_filter( \'nav_menu_roles_item_visibility\', \'custom_menu_item_visibility\', 10, 2 );
