Style Variable Product Page + Subscription

Hey guys. I want to make a page that is exactly like this: https://uk.huel.com/products/huel (this is made with Shopify, apparently)

Where the user can choose: single purchase vs subscription

And then he can choose the quantity of each variable before pressing “add to cart”.

So far I can only add one variation quantity at a time.

Thanks in advance,
Saulo
