Example: Black, Red, Galaxy Purple. Leave this empty if the item only comes in one color.

Example: Dice Book, 3-Slot Shelf, 5-Slot Shelf. Each part can have its own color choices. These do not create separate customer-facing product pages.

Build a bundle from reusable parts, sub-items, or other active listings in the same store category. The main/parent listing is only the container for these options and does not need to be added as an item in the bundle.
