如何仅下拉菜单wordpress css

Question

我需要只用 css 制作一个 wordpress 菜单（下拉式菜单）

我找不到正确的方法，也许是分配的类上的错误，但我已经尝试了一些选项，但没有解决问题，使用此代码我可以看到菜单但从不显示项目和子项目会很棒一些帮助

这是wordpress标签和代码，也是使用的css

************************************ 
             MENU
************************************
<label for="show-menu" class="show-menu">Show Menu</label>
<input type="checkbox" id="show-menu" role="button">
    <nav id="superior">
            <?php wp_nav_menu(
            array(
            'container'=> false,
            'items_wrap'     => '<ul id="%1$s" class="%2$s nav nav-pills"> %3$s</ul>',
            'theme_location' => 'menu'
            )); ?>
    </nav>

             .CSS

我将 .hidden 类更改为 .sub-menu 并且它正在工作。不确定它是否正是您正在寻找的功能：

改变了：

ul li a:hover + .hidden, .hidden:hover {
    display: block;
}

到：

ul li a:hover + .sub-menu, .sub-menu:hover {
    display: block;
}
