I noticed that the dropdown menu did not include the parent category in the child links, which means that if you also use the standard categories box, the parent categories don't open up when clicking a child category.

I not a programmer, but my quick fix was this...

in categories_ul_generator,php, around line 70,

find:

$category_link = $category_id;

Replace with:

if ($parent_id != '0') {
$category_link = $parent_id .'_'. $category_id;
} else {
$category_link = $category_id;
}

It seems to work fine, but was wondering if anyone could see potential problems or a way it could be done better
