I have my site set up so that the main site has many " root categories" i.e electronics, clothing. And my other sites have only electronics and clothing. I want the categories sidebox to display only the sub categories.

So for electronics it displays cell phones, digital cameras, etc. instead of just electronics

and for shoes it simply displays nike, reebok, etc. instead of just shoes.

I tried not including the "root category" (shoes, electronics) in the multisite tools but then no categories display
