HTML
<div class="s_h_ie">
<select id="Select1" disabled="disabled" runat="server">
<option value="寻人求助">寻人求助</option>
<option value="寻人求助">寻人求助</option>
<option value="寻人求助">寻人求助</option>
</select>
</div>
CSS
/*在IE中兼容select下拉箭头（亲测可用）*/
.s_h_ie
{
background:#fff url(../../App_Themes/default/images/select_list.png) no-repeat top 12px right 15px;
width:150px;
height:28px;
overflow:hidden;
border:1px solid #e1e1e1;
border-radius:5px;
}
.s_h_ie select
{
background:transparent!important;
padding-left:4px!important;
width:170px!important;
height:100%!important;
border:none!important;
}
在IE6里面的下拉选择框(默认)这样的，不好看
