Adding variants
You can create up to 100 variants for a product.
Each product can have up to 3 options. The options can be different from product to product. For example, one product can use size, color, and style, and another product can use weight, finish, and material.
The variant and option limits can only be increased by using a third-party app from the UniEC App Store.
If you need to sell a product that has more than 100 variants or 3 options, then you might be able to customize your theme code to extract line item properties so that you can get custom requirements from your customers.
