Choosing between variations

  • Use the Hint text variation to provide additional information that pertains to the question being asked or all of the options presented.
  • Use the Label header variation when a heading is required within the legend that acts as a label for the radio buttons. This can aid users in navigating the form questions, particularly in the sub-task pattern
  • Use the Description text variation to provide additional details about one or more radio button options. This variation is superseded by the Tile variation.
  • Use the Tile variation to provide additional details about one or more radio button options within a large and well defined tap target.

Conditionally revealed fields

In the radio button and checkbox components, we offer an option to conditionally reveal fields when the user selects an answer. These fields are often used to group related questions together by revealing a single follow-up question only when they’re relevant to the user.

Conditionally revealed fields can be used if the following conditions are met:

  1. There should only be one reveal on a page.
  2. When the revealed trigger is selected, you must be able to tab directly into the newly revealed field (Which is why we’ve put the “other” question last.)
  3. The newly revealed question field must be understood by itself. For example, don’t just say “Other”. Instead, say:

Since your relationship with the veteran was not listed, please describe it here
