dropdown_cats

Hello,

I want to use <?php dropdown_cats; ?> in my sidebar where it shows only the children_of a category.

When I use this code

<form action=”<?php echo $PHP_SELF ?>” method=”get”>
<?php dropdown_cats(); ?>
<input type=”submit” name=”submit” value=”view” />
</form>

it lists all the categories I have and this is not what I want. Before I started trying to use dropdown_cats I used wp_list_cats with the “chidren_of” function on my sidebar to limit what categories where displayed on a particular page. For example, on my homepage the categories on the sidebar where Movies, TV, Sports, & News. When you clicked on Movies you went to the movie page and the sidebar changed to display only the “children_of” the Movies category which looked something like this: American Pie, Hook, No Way Out, Pirates of the Carribean 2, Tombstone, etc.

So my question is can I get this same functionality with dropdown_cats? It seems it should be possible but I just can’t seems to figure it out.

Any help with this would be greatly appreciated.
