1.把autoComplete.php放入根目录，
在cp_mtag中查找
<div class="f_status s_clear">
<a href="javascript:;" onclick="window.scrollTo(0,0);" id="a_top" title="TOP">TOP</a>
</div>
2.把它下面的所有代码替换成这个：
3.后台更新缓存
4.这里查询的是所有tagname数据，可以根据需要添加fieldid判断。
5.演示见效果图,需要好看点，自行修改CSS。
<style rel="stylesheet" type="text/css">
._sgClass{background:white;}
.td_over{background-color:#3366cc;}
.td_out{background-color:white;}
</style>
<script type="text/javascript" >
