How to add a drop-down menu for object colors

Question

Hello everyone, I'm putting some pins up for sale that I have available in different colors, but in the available format I see that I can only select one color (mine is a multiple listing). However, I see that other sellers have a drop-down menu with the color choices to select. I can't find any instructions anywhere on how to solve this, does anyone know how to do it? Thanks in advance for any helpful advice you can give, have a good evening!
