现有一些文本连接，需要在两个连接那里实现鼠标放上去后出现下拉菜单，点菜单中项目后连接到某页去。
<tr>
<td style= "background-color: #f4f4f4; background-repeat: repeat; background-attachment: scroll; background-position: 0% 50% " width= "898 " height= "38 ">
<p align= "right " style= "line-height: 200% "> <font color= "#737573 "> <a href= "/index.htm " target= "_blank "> 首页 </a> <a href= "/aboutus.htm " target= "_blank "> 关于我们 </a> <a href= "/news/index.htm " target= "_blank "> 最新动态 </a> <a href= "/product/index.htm " target= "_blank "> 产品展示 </a> <a href= "/download/index.asp " target= "_blank "> 程序下载 </a> <a href= "/service/index.htm " target= "_blank "> 售后服务 </a> <a href= "/ask/index.htm " target= "_blank "> 网上询价 </a> <a href= "/bbs/index.asp " target= "_blank "> 技术论坛 </a> <a href= "/Contact.htm " target= "_blank "> 联系我们 </a> </font> </td>
</tr>
现在需要实现在鼠标放到产品展示上时出现下拉菜单，有三项：产品类一、产品类二、其他产品。
最简单的实现方法是什么？

用div或者window.createPopup()创建出的弹出窗口
