来个简单点的，
用层来实现。
<div id="myDiv" >菜单</div>
<input"text" name="myInput" onmouseover="document.myDiv.left=this.offsetLeft;document.myDiv.top=this.offsetTop;document.myDiv.style.display='bolck';" onmouseout="document.myDiv.style.display='none';">

shyslysky(飞天):您的代码好像不能实现鼠标离开菜单消失嘛!而且菜单的位子不能固定.

加个onmouseout吧固定位置：
PopMenu.style.posLeft=100;
PopMenu.style.posTop=100;

这段代码类似,你改改就ok了
<script language="javascript" id="clientEventHandlersJS">

</script>
<table>
<TR id="ToolItem_1" style="DISPLAY: none" height="100%">

调试易
