I am using Drupal Commerce and I would like to create product attributes. So customer can adjust some attributes before he would buy an item.
I know, that there are some commerce modules, that enable attributes / options of product. But I cannot find such module, that would enable setting attribute options separately for each product.
I have found Pricing Attributes module, but I can set options only globally, not separately for each product. I can set separately only price and enable/disable options. But I am not able to add new options.
Is it possible to add new attributes options to product using UI with some commerce module? If not, can anybody help to find documentation or API, how could I set product options programatically by myself without existing attribute modules?
