I've installed prestashop and I've created a product and created 2 products attributes:
- Brand (containing
AppleandSamsung) - Model (containing
iPhone 5,iPhone 5C,iPhone 5S,iPhone 56,Galaxy S3,Galaxy S4, etcc..)
And this is how they are arranged together:

When looking at the product this shows Brand and Model as a dropdown list, which is great, but when selecting Apple, shows ALL of the Models, and if I select Apple > Galaxy S3 just says "The product does not exist in this model".
Is there a way I can HIDE any non-matching Models based on their Brand? (When selecting Apple only the one for apple should show up).
