JS实现选择菜单栏（配合慕课网淘宝搜索框的课程）

以下是关于实现慕课网淘宝搜索框的JS代码，不过只有选择菜单栏（其余比较容易实现）。

<!doctype html>
<html>
<head>

<title>淘宝选择栏</title>
<style type="text/css">

ul{list-style:none;display:block;}
ul,li{margin:0;padding:0}
.search-choose li{display:block;height:41px;line-height:41px;overflow:hidden;text-align:center;}
.search-choose li a{text-decoration: none;color:#6c6c6c;}
.search-choose .search-selected{background:#f6f6f6;display:block;}
.trigger-hover{height:auto;}
.trigger-hover li{display:block;}
</style>
</head>

    <div class='searchbox'>
        <div class='search-choose' id='search_choose'>
