Multiple dropdowns same name


my problem is the dropdowns on this website. I know how i can cycle through the variations in the theory but here is the problem that every dropdown has the same div "div.product-variant-input". Do I miss something? Maybe with the label "color" but i dont know how.

Thanks for the help in advance

All the information about the product is the same with different colors. Do you want to extract the image link or what?

I want to scrape all varations. Chair in red with this extra and the chair but in basic black for example. Name, price, article number
