Pattern Decisions This Source Supports

Pattern Supported decision Required contract Claim note
Disclosure / details Choose disclosure details for one short optional explanation that belongs directly beside the content it clarifies. Activating the summary toggles only the one content region controlled by that disclosure. APG defines the disclosure show-hide widget, button state, and Enter or Space activation.
Expandable row Choose expandable row when the main surface is a table or list and the extra content is owned by one row. The expand control names the affected row, exposes expanded state, and controls only that row's detail region. APG disclosure guidance supports expanded state, button semantics, and Enter or Space activation.
