我需要在主菜单上的处理链接下添加一个包含3个链接的下拉菜单，似乎无法让它播放。

非常感谢任何帮助！

Answer 1

如果我理解正确，以下情况应该有效：

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;   
}

这是工作jsfiddle：http://jsfiddle.net/a9NVN/32/

您可以根据需要设置子菜单css的格式，与父元素无关。

希望我已经回答了你的问题！
