I'm using the paid theme Prestige - and I have been trying to make it so that users must select a variant before proceeding to check out.

For ex: On the product page, we can create a size variant called "Select Your Size", but users can add the product to cart with "Select Your Size" selected, instead of small, medium, large, etc..

I know it's probably just a few lines of JavaScript that needs to be added, but since I did not create the code for this theme, it's hard for me to figure out where to place it/what to replace.

Any help would be much appreciated!!
