This mod provides three drop-down select boxes which are used to select products from top category - subcat01 - subcat02 - subcat03.
The second and third drop-down are populated dynamically (using jquery) as a result of the choice made in the previous box, in my case this is used as Make-Model-Year.

The mod is designed to work with this category structure:

top-category (eg Bikes) -

    sub-category level 1 (eg Bike Manufacturer) -

        subsub-category level 2 (eg Bike model) -

            subsubsub-category level3 (eg Bike model year or year range) - which contains the products

Each subcategory is a drop-down.

As supplied in this package, the drop drowns are integrated into the header.
