I really like this dropdown catagory boxes. Ideal navigation menu for the site I am working on. The site will have main catagories and subcatagories as follows:
> Manufacturer names (HP, Canon, etc...) as main catagories.
> Product Model as sub catagories

But I want to automate a little. When user choose a main catagory, in this case manufacturer name, I like second dropdown box shows only sub catagories under that manufacturer. I know how to do in regular html coding but I have no experience in php coding or whatever X-cart uses.

I tried PhilJ's code and it works for one drop down box. But I need atleast two level dropdown and possible three level in future.
