Actually you've implemented the original nature of Switch Menu in two of your menu items : Karriere and Fagbeskrivelse and both of those items are working correctly without any problem in both IE and Firefox.
Have a look at the following code which is the correct format for the Switch Menu implementation according to the original script
Code:
<div style="padding-left: 0px; padding-top: 3px">
- <a class=menu onclick="javascript: switchmenu('sub4');" href="http://www.itko.dk/home/fagbeskrivelse/index.php">fagbeskrivelse</a><div>
<span class=submenu id=sub4 style="margin-left: 25px">
- <a class=menu_sub href="http://www.itko.dk/home/fagbeskrivelse/fageneenkeltvis.php">fagene enkeltvis</a>
</span>
Now the below mentioned code is from your page
Code:
<div style="padding-left:0px;padding-top: 3px;">
- <a class="menu" href="http://www.itko.dk/home/index.php" onclick="javascript: SwitchMenu('sub1');">Forside</a>
</div>
<span class="submenu" style="margin-left: 25px;" id="sub1"></span>
If you look at your code furnished just above, look at the line that I colored blue there is nothing to be displayed there so there is no switch menu there and I simply don't understand if you don't have a sub menu there why you used a SPAN element there.
Please let me know If I am stating some incorrect thing.
