How do I suppress a subcategory from appearing on the category list?

Hi,

In my situation I invoked the hidden option to nest 2 sub categories under a parent and in that situation only the last nested sub category is hidden. Is there a way, via CSS to hide two layers deep.

e.g.
Parent Category
sub category 1 - hide
sub category 2 - hide

The CSS provided here in the above scenario only hides sub category 2.

.category .subcategories {
      display: none;
    }

Thank you.
