Radio buttons are used when there is a list of two or more options that are mutually exclusive and the user must select exactly one choice. Radio buttons were named after the physical buttons used in old car radios to change the stations — when one of the buttons was pressed, other buttons would pop out, leaving the pressed button the only button in the “pushed in” position. The software radio button was modeled after these physical radio buttons.

Several times a month, the Four51 Customer Success Team receives questions about using radio buttons. For example: "How do I get the radio buttons to work in a variable spec? Nothing shows until I put in a default value and then it changes to a selection."

The short answer is that Four51 Storefront does not support radio buttons in the 2.0 platform since they are not mobile friendly.
