Product select dropdown issue

7 0 0

Hi everyone,

I'm trying to figure out how a product select works on a client theme. There are no variants for the products, and they're all grouped into collections and there is code that shows each colour in that collection. For a new product they're releasing, I can't figure our how to get the different sizes to show up on the select menu

This is how the products are suppose to work.

This is the new product they are releasing, and I don't know how the get the different sized to show up on the select

Any help on this would be appreciated!
