Subcategories Filter - Doesn't Collapse?

When on a Category page, there is a Subcategories filter that doesn't have the option to collapse. Is it possible to enable the ability for this filter to collapse like the rest?

Hello,

Unfortunately, no. This is a default nopCommerce functionality and is not part of the Ajax Filters plugin. The subcategories filter you are talking about is not actually a filter but rather a navigation so it cannot collapse.
