Adding variants via Handle ID

В нашият примерен CSV File, вече има добавени и опцията за импорт на разновидности - колонката Handle ID

Each product has an ID number, which is usually in the first column, and each row of information in that column is a new product.

When you import products with multiple variants, each variant has a Handle ID, into it you would indicate which product is the specific row (variant) assigned to.

When you have added a row-variant, the ID column remains blank in the specific row, and in the Handle ID column you indicate which product (ID) refers to that particular variant.
