show the subcategories of a particular category

[cartcreative]

My client is wanting to separate the category menu on her store, so that the subcategories of category 2 show in the left column, and the subcategories of category 3 show in the right column.

I can duplicate the category block so that I have one in the left and one in the right, but how do I get it to show only the subcategories from a particular category?

If anyone can help, I'd really appreciate it.

Thanks!

Please can anyone help? I've not been able to figure this out...
