Hi all, new to shopify and currently loading product into the store. As an example we have a Polo Shirt that comes in various colours and would like the user to be able to see these colours change as they select a colour from the drop down menu within the product listing. Should each of the colours available be entered as seperate products and therefore how should they then be linked to each other? Or can this all fall under the one product entry? Thanks in advance for any advice
