我正在尝试创建自定义下拉选择,就像用户注销时在 twitter 上使用的那样,直到现在我没有成功:这是我实现的,但不适用于 IE9:|

<ul id="main">
<li class="username" tabindex="1" >
<a>USER</a>
<ul class="curent_buser">
<li class="help"><a href="http://www.wikipedia.org/">Help</a></li>
<li class="logoff"><a href="http://www.wikipedia.org/">Log Off</a></li>
</ul>
</li>
</ul>
ul#main {
color: 232323;
width: 120px;
border:2px solid #ccc;
list-style: none;
font-size: 12px;
letter-spacing: -1px;
font-weight: bold;
text-decoration: none;
height:30px;
background:#f1f1f1;
}
ul#main:hover {
opacity: 0.7;
text-decoration: none;
}
#main > li{
background: url('http://cdn1.iconfinder.com/data/icons/crystalproject/24x24/actions/1downarrow1.png') 100% 0 no-repeat;
outline:0;
padding:10px;
}
ul#main li ul {
display: none;
width: 116px;
background: transparent;
border-top: 1px solid #eaeaea;
padding: 2px;
list-style: none;
margin: 7px 0 0 -3px;
}
ul.curent_buser li a {
color: gray;;
cursor: pointer;
}
ul.curent_buser{
background:lime !important;
}
ul#main li ul li a {
display: block;
padding: 5px 0;
position: relative;
z-index: 5;
}
#main li:focus ul, #main li.username:active ul {
display: block;
}
.help{
background: url("http://cdn1.iconfinder.com/data/icons/musthave/16/Help.png") no-repeat 100% center ;
height: 25px;
margin-bottom: 2px;
border-bottom: 1px solid white;
}
.help:hover{
background: #f4f4f4;
}
.logoff{
background: url("http://cdn1.iconfinder.com/data/icons/cc_mono_icon_set/blacks/16x16/on-off.png") no-repeat 100% center ;
height: 25px;
}
.logoff:hover{
background: #f4f4f4 ;
height: 25px;
}
.help a,.logoff a{
color:gray;
font-family: Museo700Regular,sans-serif;
letter-spacing: 0;
font-size: small;
}
那么如何构建一个自定义选择,就像在 twitter 上使用的选择一样?
