Radio Button
A radio button is a UI component that allows users to select one option from a predefined group of mutually exclusive choices. Unlike checkboxes, radio buttons are designed for single-selection scenarios, ensuring users can only choose one option at a time.
Why Use Radio Buttons in App Design?
Radio buttons enhance user experience by:
Clarifying Choices
Provide a clear way to select one option from a list.
Improving Usability
Prevent users from selecting incompatible or multiple options.
Organizing Input
Structure data collection in forms and surveys.
Common Use Cases for Radio Buttons
Forms
Collect user preferences like gender, payment methods, or shipping options.
Surveys and Polls
Let users select one answer from multiple-choice questions.
Settings
Allow users to toggle between exclusive configurations, like “Light Mode” and “Dark Mode.”
Best Practices for Designing Radio Buttons
Use Clear Labels
Ensure labels describe the options clearly and concisely.
Good: “Credit Card,” “PayPal,” “Bank Transfer.”
Bad: “Option 1,” “Option 2.”
Group Related Options
Use spacing and visual grouping to separate related radio button options from others.
Maintain Accessibility
Ensure radio buttons have sufficient contrast and a visible focus state.
Use ARIA attributes like role="radiogroup" and aria-checked for screen readers.
Provide Feedback
Use visual cues (e.g., color or animation) to indicate the selected option.
Optimize for Mobile
Ensure radio buttons are large enough for touch interactions.
Radio buttons are a fundamental component in UI design, offering a simple yet effective way to collect user input. By following best practices and using tools like Figma Kits and UI Kits, you can design accessible, responsive radio buttons that enhance your app’s usability.
