PHP Help? Dropdown Menu using Superfish

Okay so I’ve done some research yet my problem is a little bit more demanding. I want to create a navbar drop-down menu using superfish, I have all the superfish files required.

It’s easy enough to do for page navigation but my theme has a custom navigation bar for categories.
Since I don’t really know PHP code I’m hoping someone could help me out.

The code (from the header.php file) for the category navigation bar is shown below.

<div id="navbar">
<ul>
<?php
$eece_global_showcats = get_option('eece_global_showcats');
$eece_global_showcats_sortby = get_option('eece_global_showcats_sortby');
$eece_global_showcats_order = get_option('eece_global_showcats_order');

$eruby_cat_sort_db = array('name','ID','slug ','count','term_group');
$eruby_cat_order_db = array('ASC','DESC');
$addtionstr = '';

if ($eece_global_showcats && is_numeric(str_replace(',','',$eece_global_showcats)) ) {

if ($eece_global_showcats_order && is_numeric($eece_global_showcats_order) && $eece_global_showcats_order<2 && $eece_global_showcats_order>=0) { $addtionstr .= '&order='.$eruby_cat_order_db[$eece_global_showcats_order]; } else { $addtionstr .= ''; }

if ($eece_global_showcats_sortby && is_numeric($eece_global_showcats_sortby) && $eece_global_showcats_sortby<5 && $eece_global_showcats_sortby>=0) { $addtionstr .= '&orderby='.$eruby_cat_sort_db[$eece_global_showcats_sortby]; } else { $addtionstr .= ''; }

wp_list_categories('style=list&hierarchical=0&title_li=&include='.$eece_global_showcats.$addtionstr);

} else {
wp_list_categories('style=list&hierarchical=0&title_li=&number=9');
}
?>
</ul>
</div>

What I want to do is show the sub categories when hovering over a category using superfish, sounds easy enough, but difficult if you don’t know PHP.

I can understand if I don’t get a reply for this but thanks in advance!
