和CSS:

/* Global properties ======================================================== */

我需要在主菜单的“治疗”链接下添加一个包含 3 个链接的下拉菜单，但似乎无法正常运行。

如有任何帮助，我们将不胜感激!

如果我没理解错的话，下面的方法应该有效:

HTML:

<body>

<ul>
    <li><a>level1</a>
        <ul>
            <li><a>level2</a></li>
        </ul>
    </li>
    <li><a>level1</a></li>
</ul>

</body>

CSS:

ul {
    position:relative;
    list-style:none;
}

ul li a {
    display:inline-block;
    float:left;
    width:100px;
    height:50px;
    background:#eaeaea;
    text-align:center;
    vertical-align:middle;
    line-height:50px;
}

ul ul {
    display:none; 
    position:absolute;
}

ul li:hover > ul {
    display:block;
    top:50px;
}

ul ul li a {
    background:#a7a7a7;   
}

这里正在运行 jsfiddle:http://jsfiddle.net/a9NVN/32/

您可以根据自己的喜好设置子菜单的 CSS 格式，独立于父元素。

希望我已经回答了你的问题!
