Does anyone know a way to have each category display as a new side menu item? In essence what i want to achieve is this:

Menu A (Category 1)
- Product A
- Product B
- Product C


Menu B (Category 2)
- Product A
- Product B
- Product C


Menu C (Category 3)
- Product A
- Product B
- Product C

Any help or thoughts would be greatly appreciated! :)
