Hi ,

Another noobish question from me. Normally in the left menu , Categories are arranged this way.

Categories
- Toys
- Psp
- Blah blah ...

But I want to have two major categories such as

Electronic Categories
- PSP
- Xbox360
- blahblah

Non-Electronic Categories
- Toys
- Hankerchiefs
- blahblah

How can I do that? Thanks
