I've created new product and clicked Create Configurations at the bottom of the product page. I then clicked 'Create New Attribute', added a name for it and then a code. Once saved, I'm taken back to the Create Configurations page but my new attribut isn't listed, just the usual three (color, size and format).
Am I missing something?
You need to assign your new attributes to the attribute group. Go to store->products(Under Attribute label). Then drag your new attribute to the attribute group.
For more details about creating attribute check this link https://www.fastcomet.com/tutorials/magento2/product-attributes
The attribute must also be set to a "global" scope.
The attribute must also be "required" to be used for a Configurable product.
