Requirements: 1)In back office, creating/editing/deleting Make, Model,Year (Relation Make has many Models, Model has many years). 2)In product (back office), adding a new tab to add the Make, Model, Year for this product (product can have more than one). 3)Adding a filter in front page (make, model, year), similar with the one in the image. 4)In product page (route=product/product) adding make,model,year dropdowns with the ones available for this product and send it in the order mail info to the administrator
