Additional guidance for VA

When to consider something else

  • If there are too many options to display on a mobile screen.
  • If a user can only select one option from a list (use radio buttons instead).

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

Errors

  • Checkbox groups typically appear inside of <fieldset>s. The class name of usa-input-error may be placed on the <fieldset> that contains all of the checkboxes.
  • The error message is placed just below the <legend>.
  • See form error handling for additional guidance.
