The easiest case in your store is having a product that is unique and has no variants. But often you need to offer a product in different sizes, colors or other attribute so that your clients get exactly what they want. Sometimes, these attributes have a relationship to the price and sometimes, they have different images and descriptions.
Abricot Jam 250gr or 500gr?
Imagine you are selling home made apricot jam in two sizes, 250gr and 500gr. The 250gr pot is the standard size and costs 4 €. The 500gr pot costs 7 €. You don't want to use the inbuilt stock control system in VirtueMart to manage your jam pot stocks. You just want to offer the different sizes for a different price. The product images and the descriptions are the same.
Create a custom field
To achieve your goal you have to create a custom field. Go to Components -> VirtueMart -> Products -> Custom Fields and create a new field. Choose a name (e.g. pot), as type Cart Variant and Yes for Cart Attribute (Figure 1).
