In Drupal Commerce (D7), when multiple products are referenced by a product display, they appear on the product display as a select list, but I can also choose radio buttons.
The trouble is, some of my products displays reference one product and some reference multiple. If I only reference one product, there is no select list or radio button. In other words:
Product 1: "black", "red", "blue" Product 2: "red"
On product 1's page, there will be options for all 3 colors On product 2's page, there will be no color options.
Even though you can't choose from more than one options with product 2, I still want the select list/radio button to display so customers know what color option is available.
How would I do this?
