Wordpress Show subcategories only under current category

I have busted my brains out to find out how to show subcategories only under the current category in wordpress.
mainly there are a lot of plugins who do that, but I had a couple of problems:
1. I was working with the a different language than english - and RTL (hebrew)
2. I was working with a custome design I have made which had some changes to the classes.php file.
I have managed to perform this using a simple elseif:
in the wp-cinludes/classes.php file change:
$top_level_elements = array();
$children_elements = array();
foreach ( $elements as $e) {
if ( 0 == $e->$parent_field )
$top_level_elements[] = $e;
else
$children_elements[ $e->$parent_field ][] = $e;
}
into:
$top_level_elements = array();
$children_elements = array();
foreach ( $elements as $e) {
if ( 0 == $e->$parent_field )
$top_level_elements[] = $e;
elseif ($e->$parent_field == $_GET['cat'])
$children_elements[ $e->$parent_field ][] = $e;
}
notice the "else" is changed to:
elseif ($e->$parent_field == $_GET['cat'])
good luck!
