How to deselect a radio variant

Hi everyone,

I need to make my visitor select a variant before add to cart.
Natively shopify preselect the first variant.

But that make my sav a nightmare.

I tried some custom js code but nothing worked.

Do you have some ideas ?

Hi @Arthursimonianfyrre

Welcome to the community.

It depends on your theme and the custom code you did. Any chance to share a link to your store, and if the frontend is password-protected, can you share the password too?
