Radio Buttons
Radio buttons are a type of graphical user interface (GUI) element that allows users to select exactly one option from a mutually exclusive set of choices. They are commonly used in forms, settings dialogs, and surveys where only a single selection is permitted from multiple options. When one radio button is selected, any previously selected button in the same group is automatically deselected.
Developers should use radio buttons when designing interfaces that require users to make a single, exclusive choice from a list of options, such as selecting a gender, payment method, or subscription tier. They are essential for ensuring data integrity in forms by preventing multiple selections where only one is valid, and they provide clear visual feedback to users about their current choice.
