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.
