Hi, I created a menu in html/css but where I wanted the subitems to be shown on parent item hover. The problem is when I hover on it in IE it only shows it's subitems when I hover on the text in the menu item, If I hover over the element and not the text the subitems disappear again. So if I hover and want to move my mouse to my submenu the submenu disappears unless I'm fast enough. This is very annoying, does anyone know how I can solve this?

MY menu code is like so:

<ul id="leftnav">

  • Item1
    • SubItem1
    • SubItem2
    • SubItem3

  • Item2
    • SubItem1
    • SubItem2
    • SubItem3

    The menu should be a left sided menu which shows it's subitems only on hover, so I used css to achieve this with the following code:

    #leftnav, #leftnav ul
    {
     padding: 0;
     margin: 0;
    }
    
    #leftnav ul li
    {
     margin-left: 102px;
     position: relative;
     top: -19px; /*sets the childitems on the same height as the parent item*/
    }
    
    #leftnav li
    {
     float: left;
     width: 100px;
    }
    
    #leftnav ul
    {
     position: absolute;
     width: 100px;
     left: -1000px; /*makes it disappear*/
    }
    
    #leftnav li:hover ul, #leftnav li.ie_does_hover ul
    {
     left: auto;
    }
    
    #leftnav a
    {
     display: block;
     height: 15px;
     margin-top: 2px;
     margin-bottom: 2px;
    }
    

    Since this only works with firefox I also had to insert a javascript to get this to work in IE using code:

    <script language="JavaScript">
     sfHover = function()
     { 
      var sfElsE = document.getElementById("leftnav").getElementsByTagName("LI");
      for (var i=0; i<sfElsE.length; i++)
      {
       sfElsE[i].onmouseover=function()
       {
        this.className+=" ie_does_hover";
       }
       sfElsE[i].onmouseout=function()
       {
        this.className=this.className.replace(new RegExp(" ie_does_hover\\b"), "");
       }
      }
     }
     if (window.attachEvent) window.attachEvent("onload", sfHover);
    </script> 
    

    Many many many thanks for replies
