html - 需要制作 3 级纯 css 菜单

Question

我制作了 2 个级别的纯 css 菜单。但现在我需要将其制作为 3 个级别。我尝试了很多次但不适合我。这是 jsfiddle .我不需要任何 jquery 代码，只需要纯 css。

CSS

#menu {
    width: 980px;
    height: 30px;
    float: left;
    border-top: dashed 1px #d8d8d8;
    margin-left: 7px;
}

    width: 996px;
    margin: 0px;
    padding: 0px;
    margin-top: 10px;
}

    font-size: 14px;
    color: #860300;
    margin-right: 16px\9;  /* IE8 and below */
    position: relative;
    height: 30px;
}
