I have some markup for a popup menu that works in firefox but not IE. The problem is that the popup pops under other elements and is impervious to the z-index value. A complete runnable example is below.
Now, I know that one fix is not to position the divs as relative, but I can't do that because, in the real code, I'm using scriptaculous and it adds the "position: relative" to do what it needs to do. Besides, I don't think it should matter.
Is there another fix that would make this code work for both IE and firefox?
Example:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head><title>IE Problem</title>
<style type="text/css">
.mydiv{
position: relative;
background: yellow;
border: solid 1px black;
}
table{background:black;}
td.menu{background:lightblue}
table.menu
{
position:absolute;
visibility:hidden;
z-index:999;
}
</style>
<script type="text/javascript">
function showmenu(elmnt){
document.getElementById(elmnt).style.visibility="visible";
}
function hidemenu(elmnt){
document.getElementById(elmnt).style.visibility="hidden";
}
</script>
</head>
<body>
<div class="mydiv" onmouseover="showmenu('one')" onmouseout="hidemenu('one')">
<a href="#">div one</a><br />
<table class="menu" id="one" width="120">
<tr><td class="menu"><a href="#">Item 1</a></td></tr>
<tr><td class="menu"><a href="#">Item 2</a></td></tr>
</table>
</div>
<div class="mydiv" onmouseover="showmenu('two')" onmouseout="hidemenu('two')">
<a href="#">div two</a><br />
<table class="menu" id="two" width="120">
<tr><td class="menu"><a href="#">Item 1</a></td></tr>
<tr><td class="menu"><a href="#">Item 2</a></td></tr>
</table>
</div>
</body>
</html>
