Once you have created a product, you will have the possibility to create its possible variables, for example different colors or sizes, so as not to have to create new products every time they have small characteristics that differentiate them from each other. To create a variant, simply scroll down to the bottom of the product page and click on "Create new variant".
At this point, all you have to do is enter the variant name, its options and any price differences with the original product variant. It is possible to make the selection of the variant mandatory or not, as well as the maximum number of variants that can be selected.
Once you have completed configuring the variants, click on "Save" at the bottom of the page.
