<style type="text/css">
#choice_list_district{
height:50px;
}
#tab td{
cursor:pointer;
}
#divobj{
position:absolute; 
width:200px; 
height:200px; 
background:blue; 
border:1px solid block; 
display:none; 
z-index:9999;
}
</style>
<script type="text/javascript" src="mytest/jQuery/jquery-1.8.3.js"></script> 
<script type="text/javascript"> 
$(function (){ 
$("#choice_list_district a").click(function(e){ 
if($("#divobj").css("display")=="none"){ 
e.stopPropagation(); 
var offset=$(e.target).offset(); 
$("#divobj").css({top:offset.top+$(e.target).height()+"px",left:offset.left}); 
$("#divobj").show(); 
}

}); 
}); 
</script>
