HikaShop does not support IE6. I don't have IE6 so I can't even look at the problem.
However, the module categories listing in accordion uses the joomla accordion system. If that doesn't work in IE6, the problem must come from that joomla library not handling it.
I'm sorry but I can't help you on that one.
