Radio Button


The radio button provides users with a set of options and the user can select one option only. Each option is represented by a radio button. Radio buttons work in groups only.


  • By default display a label, unless the combo box is next to another control that already has a label.
  • When using a radio button group in a form, show the group label and the first option in the same row and show all of the following options below the first option.
  • Keep the options as short as possible.
  • Wrap long text.
  • Define a default selection whenever possible.
  • Sort options alphabetically, numerically, or logically to help users find the right option quickly.


  • Don’t use radio buttons in a table cell. Consider using the switch control and checkbox control instead.
  • Don’t truncate long text.
