You need to create a variable product.
A variable product is a product that has more than one option in attributes, for example, color, size, material. Instruction on how to create an attribute is here: https://woocommerce.com/document/managing-product-taxonomies/
As soon as the necessary attributes are available, a variable product can be created, instructions on how to create a variable product are here: https://woocommerce.com/document/variable-product/
