GOV.UK Accessibility in government: conditionally revealed questions
Documents GOV.UK radio and checkbox components offering conditional reveal fields, common use for related follow-up questions, and accessibility risk where screen reader users may not be notified when new follow-up content appears.
Pattern Decisions This Source Supports
| Pattern | Supported decision | Required contract | Claim note |
|---|---|---|---|
| Conditional reveal fields | Choose conditional reveal fields when one option needs a short, directly related follow-up field in the same local context. | Selecting the trigger shows the related field immediately under that trigger. | GOV.UK accessibility research supports the related-follow-up use case and the need to consider whether newly revealed questions are announced. |
| Required field hidden by conditional logic | Flag this anti-pattern when a required field can block submit while it is hidden, collapsed, disabled, off-screen, absent from the current route, or disconnected from its trigger. | Selecting a trigger that creates a required follow-up reveals that follow-up immediately in logical DOM and visual order. | GOV.UK accessibility research supports the risk that newly revealed conditional questions may be missed by assistive technology users. |
