How to Add Product Options in WooCommerce?

We can add product options in WooCommerce like a shirt, where you can offer a large, medium and small and in different colors.

Go to WooCommerce > Products.
Select the Add Product button or Edit an existing product.
Then go to Product Data > Attributes section.
Select one from the drop-down and Add.
Choose Select all to add all attributes to the variable product (if applicable).
Check the Used for variations checkbox to tell WooCommerce it’s for your variations.
