Variations are the selection of your products such as sizes, color or even type of materials.
To start setting up your variations, select Product Variations from the Product tab.
Click Add New Variation to begin.
Give your variation a name, for its intended product and list the options in the given fields.
Remember to click Add Variation to save your variation.
Create as many variations as you like and later assign them to the relevant products. Variations can also be edited to change the number of options or deleted. But bear in mind that only one variation can be assigned to one product.
