html - 制作整体（链接）垂直菜单

Question

有什么想法可以让 LI 成为整个链接吗？

#nav{
position: relative;
width: 120px;
}
#nav a {
display: inline;
width: 100%
text-decoration: none;
}
#nav ul{
list-style-type: none;
}
#nav ul li{
background: #c0c0c0;
border-bottom: 1px dotted #404040;
}
#nav ul ul{
position: absolute;
left: 81px;
display: none;
}
#nav ul ul li{
background: #c0c0c0;
}
#nav ul li:hover ul{
display: inline;
}

这是链接： jsfiddle

我尝试过的选项：

1. 一个{显示：块；} --> 这行得通，但第二个 UL 下降了。
2. a {display: inline-block;} -->第二个 UL 问题已修复，但 LI 不是链接。
3. 一个{显示：内联块；宽度：100%；高度：100%；} --> 与 2 相同。

提前致谢。

Answer 1

It's because of the padding that it doesn't work. The element is actually overlapping the others.

#nav ul ul{
    position: absolute;
    top:0px;
    left: 80px;
    display: none;
    padding-left:0px;
}

#nav a {
    display: block;
    text-decoration: none;
    float: left;
    width: 80px;
}

#nav ul li{
    background: #c0c0c0;
    border-bottom: 1px dotted #404040;
    overflow:hidden;
}

    text-decoration: none;
    }

试试这样

            #navbar ul li {
            display: inline;
            position: relative;
            }

            #navbar ul li ul  {
            position: absolute;
            visibility: hidden;
            }

            #navbar ul li:hover>ul {
            visibility: visible;
            position: absolute;
            display: block;
            }

            <div id="navbar">
                <ul>
                    <li><a href="link">1</a></li>
                    <li><a href="#">2</a>
                        <ul>
                            <li><a href="link">x</a></li>
                            <li><a href="link">y</a></li>
                            <li><a href="link">z</a></li>
                        </ul>
                    </li>
                    <li><a href="link">3</a></li>
                </ul>
            </div>
