Radio Button
Radio Button is a small circular control that lets users select exactly one option from a list of mutually exclusive choices.

A radio button is a small circle that fills when selected, limiting users to one choice per group. Once they pick an option, any previously chosen circle in that group is automatically cleared, ensuring only a single selection remains active.
Because radio buttons dictate exclusive choices—like shipping methods or subscription tiers—they’re used where multiple valid options exist, but only one should apply at a time. Their distinctive design and explicit labels keep the decision-making process straightforward and final.
