The Radio field lays all options out in the open as radio buttons, so customers see every choice at once and pick exactly one. Each choice can add to or subtract from the price, show an image, and optionally carry a quantity input. Best for short lists where visibility matters.
Use Cases #
- “Pizza Size: Small / Medium (+$3) / Large (+$6)” — Classic single-pick where all prices should be visible upfront.
- “Warranty: 1 Year (+$0) / 2 Years (+$19) / 3 Years (+$29)” — Tiered upsell laid out side by side.
- “Roast Level: Light / Medium / Dark” — Equal-priced choices that just need a clear pick.
- “Choose a Crust” with thumbnails — Visual single-pick using the per-choice image option.

How to Use #
- Open Optiontics → Add-ons and edit (or create) an add-on form.
