在nav标签内添加动态wordpress/genesis菜单，并使其隐藏。 _nav

首先, 让我解释一下我要达到的目标：
在由StudioPress重新设计Wordpress Genesis-sample主题时, 我决定仅对所有显示分辨率使用响应菜单(移动菜单, 带有汉堡图标的菜单)。我已经将菜单附加到的右钩子上, 并按自己的喜好设置了部分样式, 还设置了移动菜单以在所有媒体查询中显示。
我接下来要做的是在主菜单(nav-primary)的下面, 在标签内添加我的自定义菜单(已创建), 以便它与单击一起显示和隐藏。
我尝试使用nav-extras将我的代码片段添加到标签的末尾, 其中以下代码来自创世纪摘要库：

// Adding custom menu supportadd_theme_support( 'genesis-menus', array( 'primary'=> __( 'Header Menu', 'genesis-sample' ), 'secondary' => __( 'Footer Menu', 'genesis-sample' ), 'custom' => __( 'Custom Menu', 'genesis-sample' ), ) ); //My custom menu function function add_custom_menu() {// Do nothing if menu not supported.if ( ! genesis_nav_menu_supported( 'custom' ) || ! has_nav_menu( 'custom' ) ) { return; }$class = 'menu genesis-nav-menu menu-custom'; if ( genesis_superfish_enabled() ) { $class .= ' js-superfish'; }genesis_nav_menu( array( 'theme_location' => 'custom', 'menu_class'=> $class, ) ); }// Add typical attributes for navigation elements.add_filter( 'genesis_attr_nav-custom', 'genesis_attributes_nav' ); add_filter( 'genesis_attr_nav-custom', 'my_skiplinks_attr_nav_custom' ); /** * Adds ID markup to custom navigation. * * @param array $attributes Existing attributes for custom navigation element. * @return array Amended attributes for custom navigation element. */function my_skiplinks_attr_nav_custom( $attributes ) {$attributes['id'] = 'genesis-nav-custom'; return $attributes; }add_filter( 'genesis_skip_links_output', 'my_skip_links_output' ); /** * Adds skip link for custom navigation. * * @param array $links Exiting skiplinks. * @return array Amended skiplinks. */function my_skip_links_output( $links ) {if ( genesis_nav_menu_supported( 'custom' ) & & has_nav_menu( 'custom' ) ) { $links['genesis-nav-custom'] = __( 'Skip to custom navigation', 'genesis' ); }return $links; }//Adding custom menu to < nav> tagadd_filter( 'wp_nav_menu_items', 'theme_menu_extras', 10, 2 ); /** * Filter menu items, appending either a search form or today's date. * * @param string$menu HTML string of list items. * @param stdClass $args Menu arguments. * * @return string Amended HTML string of list items. */ function theme_menu_extras( $menu, $args ) { //* Change 'primary' to 'secondary' to add extras to the secondary navigation menu *// if ( 'primary' !== $args-> theme_location ) return $menu; $menu .= '< div id="sub-menu"> '. add_custom_menu() .'< /div> '; return $menu; }

结果是, 即使我添加的div也未放置到位。可以找到我的路。帮助将不胜感激:), 在此先感谢你。
#1我已经解决了：

// Hide/display on mobile-menu button clickwindow.onclick = hideFunction; function hideFunction() { let x = document.getElementById("genesis-mobile-nav-primary").getAttribute("aria-expanded"); if (x == "true") { document.getElementById("genesis-nav-custom").style.display = "block"; } else { document.getElementById("genesis-nav-custom").style.display = "none"; }; }// Create custom menu and hook into the header just under < nav> (the primary navigation) tag// Register the custom menus.function register_additional_menu() { register_nav_menu( 'custom' , __( 'Header Submenu' )); } add_action( 'init', 'register_additional_menu' ); /** * Echoes the "Custom Navigation" menu. */ function custom_do_nav() { $class = 'custom'; if ( genesis_superfish_enabled() ) { $class .= ' js-superfish'; }genesis_nav_menu( array( 'theme_location' => 'custom', 'menu_class'=> $class, 'menu_id'=> 'custom-menu', ) ); }// Add typical attributes for navigation elements. add_filter( 'genesis_attr_nav-custom', 'genesis_attributes_nav' ); add_filter( 'genesis_attr_nav-custom', 'skiplinks_attr_nav_custom' ); /** * Adds ID markup to custom navigation. * * @param array $attributes Existing attributes for custom navigation element. * @return array Amended attributes for custom navigation element. */ function skiplinks_attr_nav_custom( $attributes ) {$attributes['id'] = 'genesis-nav-custom'; return $attributes; } // Custom menu action hook add_action( 'genesis_header', 'custom_do_nav', 12 );

【在nav标签内添加动态wordpress/genesis菜单，并使其隐藏。】就是这样:)
