Is there any way to split the main category menu into separate sub menus?

Hey everyone,

Hope everything’s kicking along.

Relatively new to CS-Cart and before I go off and start hacking away. I thought I’d ask a quick question to see if theres a way of splitting the main menu into sub menus?

For example, lets say theres three sub menus under the main (root) category (brands, colours, sizes). Is that any way to turn those three sub categories into separate drop down menus?

Any help’s much appreciated.
