我是Wordpress社区的新成员，目前我正致力于将静态HTML网站转换为WP平台。我的主题中几乎所有内容都有一个例外：导航菜单。
我正在尝试使用内置的导航功能，我很确定我已经在其他WP网站上看到了这一点，但我很难找到帮助来指导我完成这个领域（我为此道歉）已经在stackoverflow上询问了这个场景，我现在已经搜索了几天，也许我只是使用了错误的术语？）。
这是我的测试基地：http://ahathaway.n120.fiercethought.net/consumer-support/
该链接将带您进入网站上唯一一个应该有“子菜单”的部分，而我想要完成的是当用户导航到任何子网时子菜单保持扩展状态-menu项目（即如果您点击“会员表格”，子菜单不应该像当前那样消失。）
我不确定我到底缺少什么，而且我迫切需要在正确的方向上轻推，所以任何帮助都会非常感激！谢谢！
这是我的相关代码（如果您需要/想要查看其他任何内容，请告诉我，我试着保持这篇文章的简洁，至少在最初时）：
来自header.php：
<!-- Begin navigation menu -->
<?php
// Top navigation menu
wp_nav_menu( array(
'theme_location' => 'top-navigation',
'menu_id' => 'nav',
'menu_class' => 'left',
'depth' => 2,
'walker' => new Walker_Nav_Menu));
?>
<!-- End navigation menu -->
这是style.css（因为这是一个转换，需要看起来尽可能接近相同，所以很多CSS保持不变：

有一个名为current_page_item的类负责菜单扩展。该类出现在li#menu-item-30的链接中。但是，current_page_item不存在，并由current_page_parent替换为子页面。这就是它没有显示的原因。
因此，我建议您在样式表中复制使用current_page_item的每个DOM标识符，并将current_page_parent放在其位置。这就是我的意思：
<强>之前：
#nav li.current_page_item ul li a, #nav li.parent-here ul li a { color: #fff; font-size: 13px; font-weight: normal; text-transform: none; text-decoration: none; height: auto; line-height: 16px; width: 175px; display: block; padding: 10px 20px 0 20px; background-image: none !important; background-color: #082640 !important;}
<强>后：
#nav li.current_page_parent ul li a, #nav li.current_page_item ul li a, #nav li.parent-here ul li a { color: #fff; font-size: 13px; font-weight: normal; text-transform: none; text-decoration: none; height: auto; line-height: 16px; width: 175px; display: block; padding: 10px 20px 0 20px; background-image: none !important; background-color: #082640 !important;}
为您找到的current_page_item的每个实例执行此操作，您应该很高兴。
顺便问一下，您使用的是Firebug还是Chrome / Safari开发人员工具？它们对调试这些类型的问题非常有用。这基本上就是我所做的一切。 ：）

我认为你还没有提到当前班级的任何造型
current_page_item这是保持菜单打开的类
在Css中您可以实现此样式：
#access {display: block; margin: 0 auto; width: 990px; z-index:999;}
#access .menu-header, div.menu {font-size: 13px; width:100%; float:left; height:42px; margin-top:10px; background:#F7F7F7;border:1px solid #e3e3e3; border-bottom:3px solid #e3e3e3;}
#access .menu-header ul, div.menu ul {list-style: none; margin: 0;}
#access .menu-header li, div.menu li {float: left; position: relative;padding-right:0px; z-index:9999;}
#access a {color: #fff; display: block; line-height: 35px; padding: 0 25px; text-decoration: none; font-size:14px;}
#access ul ul {display: none; position: absolute; top:42px; left:0px; float: left; width:170px; z-index: 999999999; background:#E3E3E3; padding:10px 6px 7px 10px;}
#access ul ul li {min-width:165px;}
#access ul ul ul {left: 100%; top: 0;}
#access ul ul a {line-height: 1em; padding:5px 10px; width:146px; height: auto; font-size:14px; text-transform:capitalize; margin-bottom:3px; background-color:#F7F7F7;}
.sub-menu li {background:none!important;}
/*.current_page_item > a{background-color:#BE100F; height:35px;}*/
.menu .sub-menu .current_page_item > a{background:none;}
.menu .current_page_item > a{background-color: #e3e3e3!important; color: #333 !important;}
.menu .current-menu-parent > a{background-color: #e3e3e3!important; color: #333 !important;}
#access ul ul :hover > a {background-color:#336699; color:#FFFFFF;}
#access ul li:hover > ul {display: block;}
在PHP中：
<div id="access">
<?php
$args = array(
'theme_location' => 'header_menu',
'menu' => 'Main Menu',
'sort_column' => 'menu_order',
'container_class' => 'menu-header'
);
wp_nav_menu($args);
?>
</div>
