What is a Radio Button?

A radio button is an input element that allows users to select one option from a predefined group. It is commonly used in forms and surveys to facilitate single-choice selections.

When to use Radio Button?

Radio buttons should be used when you want to present users with multiple options, but only allow them to select one at a time. This is useful in scenarios where a single choice is required, such as selecting a payment method or choosing a preferred contact method.

When not to use Radio Button?

Avoid using radio buttons when there are too many options, as this can overwhelm users and make the interface cluttered. Additionally, if users need to select multiple options, checkboxes would be a more appropriate choice.

What is the anatomy of a Radio Button?

The anatomy of a radio button includes the circular input area that indicates a single selection, a label that describes the option, and often, an accompanying visual indicator that shows which option is currently selected. The design typically features a clear distinction between selected and unselected states to enhance user experience.
