Radio Button

A radio button allows users to select only one value in a list of two or more options.

Radio buttons are used for mutually exclusive choices, not for multiple choices. Only one radio button can be selected at a time. When a user chooses a new item, the previous choice is automatically deselected.

When creating Radio Button :

  • Make sure that the purpose and current state of a set of radio buttons is explicit.
  • Limit the radio button’s text label to a single line.
  • If the text label is dynamic, consider how the button will automatically resize and what will happen to any visuals around it.
  • Use the default font unless your brand guidelines tell you otherwise.
  • Don’t put two RadioButtons groups side by side. When two RadioButtons groups are right next to each other, it can be difficult for users to determine which buttons belong to which group.
