Theme with product variants placed horizontally

I am looking for a responsive Theme or DIY solution to place product variants (associated products) horizontally when the browser is opened wide enough (e.g. four variants in a row) and not below each other as it is done in all themes I looked at.

Is there anybody aware of such a Theme exists?

Hello,

You can take a look at our Prisma Theme. The product variants are placed horizontally there, but there are only two product variants per row.

If that suits you, this theme can be your solution. Also, it can be customized to display more than two on a row.
If you decide to buy our products, our support team can provide you with help on how to add such small customizations.

I hope I was helpful,
Nikola
