html - 当 parent 有文本装饰时摆脱嵌套的 li 文本装饰

Question

http://jsfiddle.net/Lqvcr/53/

这太他妈基础了，我不知道如何让它发挥作用。

如何在下拉列表 anchor 没有下划线的情况下保持 .selected 类有下划线？

HTML:

<ul id="nav">
    <li>
        <a href="about.html">about</a>
    </li>
    <li>
        <a href="about.html">about</a>
    </li>
    <li class="selected">
        <a href="work.html">Work</a>
        <ul id="second" class="vis">
            <li>
                <a href="graphicdesign.html">Graphic Design</a>
            </li>
            <li>
                <a href="illustrations.html">Illustrations</a>
            </li>
        </ul>
    </li>
    <!-- etcetera -->

CSS:

ul#nav {
    position: relative;
    margin-left: 0;
    padding-left: 0;
    display: inline;
}
ul#nav li {
    margin-left: 0;
    padding: 3px 15px;
    list-style: none;
    display: inline;
}
ul#nav li.first {
    margin-left: 0;
    border-left: none;
    list-style: none;
    display: inline;
}
ul#second {
    position: absolute;
    right: -57px;
    display: none;
}
.selected {
    text-decoration: underline;
}
.selected:hover ul#second {
    display: block;
}
.selected:hover ul#second li a {
    display: block;
}
a {
    text-decoration: none;
}

只需更改这一行:

.selected a{text-decoration:underline;}

对于这个:

.selected > a{text-decoration:underline;}
