Parent attribute to category?

On my site, people will be able to select a “make” and a “model”. How do I parent a particular “model” option to a particular category, so that my “featured categories” section is correctly populated? Should there perhaps be a “category” selection made before the user fills out the listing attributes?

Please consider using a single Select attribute for this purpose, and set models as child options of make options. Then you can set this attribute display format:

%parent_value% %value%

Selecting a model in this list will result in something like “Toyota Corolla”, showing both the model and the make.

Thank you I will try this.
