Focal Theme - Change Variant Box Appearance

[hdkingy]

I am looking to change the variant selector dropdowns on my product pages to a standard type, like what is pictured below:

My theme uses this sort of selector by default on contact forms, but not on the product pages, so I am assuming this is possible to achieve.

Here is a link to my site if needed: https://pondstream.com/products/kasco-floating-surface-aerator

Thank you!
