转载的代码，用div实现，楼主参考：
<body>
<table border="0" cellpadding="0" cellspacing="0">
<tr>
<td>所属区域</td>
<td>
<br><br>
<input type="text" id="txtRegion" />
<div id="divRegionList" style="display: none; border: 1px solid #0000ff; overflow: hidden; height: 150px; position: absolute; background-color: #ff0000;">
<table width="100%" border="0" cellpadding="0" cellspacing="0">
<tr>
<td>
<div style="overflow: auto; width: 100%; height: 132px; background-color: #90EE90;">
<ol>
<li>北京</li>
<li>天津</li>
<li>上海</li>
<li>重庆</li>

<li>江苏</li>
<li>浙江</li>
<li>内蒙古</li>
</ol>
