Project Description:
We're in need of a JavaScript expert to add dropdowns to our categories which lists the subcategories. Here's the website:
http://www.itsasteal.ca/

Additional categories and subcategories will be added in the future so code must be automatically implemented.

We're looking for simple dopdown symbols:
[+] = Expand
[-] = Collapse

We'd like to add that the [+] (expand) option does not show unless there is a subcategory. Furthermore, the parent categories (ie. Auto, etc. ) must have the drop option.

Auto > Boats, cars, etc.
as well as:
Auto > Boats > speedboats, row boats, etc.

Here's something similar:
