html - sf-menu 下拉菜单不显示

Question

我想在我的博客上获取下拉菜单，但没有结果。我相信主题中存在下拉菜单，因为我可以在 CSS 中看到一些证据。这是我第一次来这里，所以我会尝试非常具体

 <div id='nav1-wrapper'>
<div id='nav1'>
        <ul class='sf-menu sf-js-enabled'>


<li class='cat-item'><a expr:href='data:blog.homepageUrl' title='Home'>Home</a></li>
          <ul>
        <li>
        <a href=''><span>About Us</span></a>
        </li>
      </ul>
    <li class='cat-item'><a expr:href='data:blog.homepageUrl + &quot;feeds/posts/default&quot;' title='Posts RSS'>Posts RSS</a></li>
    <li class='cat-item'><a expr:href='data:blog.homepageUrl + &quot;feeds/comments/default&quot;' title='Comments RSS'>Comments RSS</a></li>
    <li class='cat-item'><a href='#' title='Edit this link'>Edit</a></li>

        </ul>
    </div>
</div>

在测试模式下，我试图在主页下找到“关于”，但它不起作用，而是变成了一个新的主菜单。

这是CSS

    #nav1-wrapper {

}
#nav1 {
    font-size: 13px;
    height: 37px;
        width:978px;
margin-left:auto;
margin-right:auto;

}
#nav1 ul.sf-menu li ul.children li ul.children li {
    background: url(http://3.bp.blogspot.com/_WoCJXgXotb8/Suk0vKvLK4I/AAAAAAAABWE/18lJ8uP1Aes/s1600/ul_children_li_bg.gif) no-repeat bottom right;
}
#nav1 ul.sf-menu li ul.children li ul.children a {
    color: #bebebe;
    text-decoration: none;
}
#nav1 ul.sf-menu li ul.children
{
    margin:5px 0 0 0;
}
#nav1 ul.sf-menu li ul.children ul.children
{
    margin:-1px 0 0 27px;
}

我编辑了问题以便提供完整的 html 和 css 代码。谢谢网址:http://thebusywire.blogspot.com/

您必须将类“children”附加到包含 child 的 ul。在本例中是“关于我们”。

<ul class='sf-menu sf-js-enabled'>
    <li class='cat-item'><a expr:href='data:blog.homepageUrl' title='Home'>Home</a>
        <ul class="children">
            <li>
                <a href=''><span>About Us</span></a>
            </li>
        </ul>
    </li>
    <li class='cat-item'><a expr:href='data:blog.homepageUrl + &quot;feeds/posts/default&quot;' title='Posts RSS'>Posts RSS</a></li>
    <li class='cat-item'><a expr:href='data:blog.homepageUrl + &quot;feeds/comments/default&quot;' title='Comments RSS'>Comments RSS</a></li>
    <li class='cat-item'><a href='#' title='Edit this link'>Edit</a></li>
</ul>
