When to use an emphasized radio group?

Emphasized radio group is optimal for forms, settings, and other scenarios where the radio group need to be noticed. Default radio group is optimal for application panels where all the visual components are monochrome in order to direct focus to the canvas.

Use radio buttons for mutually exclusive options

Radio buttons and checkboxes are not interchangeable. Radio buttons are best used for selecting a single option from a list of mutually exclusive options. Checkboxes are best used for selecting multiple options at once (or no options).

Always label radio groups

Radio groups should always have a label that clearly describes what the list of options represents. This is important for accessibility, since a screen reader will read the label before each option. Make sure to include a label, and don't assume that the options are self-explanatory without one. Write the label in sentence case.

Radio group, switch, or checkbox?

Radio buttons are best when only one option can be selected at a time from a set (e.g., choosing one preference or mode).

Switches are best for communicating activation (e.g., turning a setting on or off).

Checkboxes are best for communicating selection (e.g., selecting multiple items from a list).
