ExpandableListProps

Prop	Type	Default	Description
items*	`readonly TItem[]`	-
renderCollapsed	`((item: TItem, index: number, expanded: boolean) => ReactNode) \| undefined`	-	Renders the always-visible row shown before expansion (and while collapsed). Receives the current expanded state so the caller can adapt its own chrome (e.g. a chevron) without extra plumbing. When omitted (together with `renderExpanded`), each item renders using the built-in default design, driven directly by `TItem`'s `ExpandableListDefaultItem` fields. Supply both to fully replace the row design with your own.
renderExpanded	`((item: TItem, index: number) => ReactNode) \| undefined`	-	Renders the panel revealed after expansion. Only mounted while the item is expanded. See `renderCollapsed` for the default-design fallback.
renderExpandedContent	`((item: TItem) => ReactNode) \| undefined`	-	Extra content appended to the expanded body, below the description. Only used by the built-in default row design.
onViewDetail	`((item: TItem) => void) \| undefined`	-	Shows a "View detail" action row and fires on click. Only used by the built-in default row design.
variant	`ExpandableListVariant \| undefined`	-
allowMultiple	`boolean \| undefined`	-	Allow more than one item to be expanded at a time. Defaults to false (accordion behavior).
disableCollapse	`boolean \| undefined`	false	Renders every item permanently expanded and removes the collapse affordance (no toggle button, no chevron). Use for a list that should always show full detail with no accordion behavior.
expandedIds	`readonly string[] \| undefined`	-	Controlled expanded item ids. Provide together with `onExpandedChange` to fully control expansion state.
defaultExpandedIds	`readonly string[] \| undefined`	-	Initial expanded item ids for uncontrolled usage.

lucide-react@^1.7.0class-variance-authority@^0.7.1

Changelog

0.4.0

Add disableCollapse prop to prevent collapsing an already-expanded row; include it in the useCallback dependency array for the expand toggle handler.
Expand ExpandableList.types.ts: add DecisionLogEvent, DecisionLogEventType types and optional events, act_by_reason, act_by_deadline, banner (now string | null) fields.

0.3.9

Fix cross-item imports to use canonical @/components paths; add missing signalos.category to manifests.

expandable-list

0.3.8

Split the built-in row design into components/ExpandableListDefaultRow.tsx. ExpandableList.tsx had crossed the 500-code-line ceiling that max-lines now enforces as an error. Pure move — no behaviour change, and the 16 existing tests cover it unchanged. Consumers pulling this widget now receive one extra file (declared in registry-item.json).

0.3.7

Merge of fix/cli-security-hardening into main. Adds the disableCollapse prop (row always renders expanded, no toggle affordance) and derives each row's -header/-panel test ids from its own per-item data-testid instead of a single list-level id, so multiple rows are individually addressable. Additive: callers that pass neither keep the previous behaviour.

0.3.6

0.3.5

0.3.4

0.3.3

Add a normal size variant and a disableCollapse prop that renders every item permanently expanded with no toggle affordance. Genericize the item types so the widget no longer needs domain-specific event types. Additive; existing callers keep the previous default/compact behavior.

0.3.2

Use semantic status tokens (text-text-error, bg-bg-warning, border-border-, bg-status-) instead of raw palette scales so client theme overrides restyle status colors.

0.3.8

Replace raw scale tokens with semantic tokens.

Content sync fix to bring source in line with published registry payload.

0.3.0

Restructured to the standard widget file contract: folded the previously separate ExpandableList.skeleton.tsx, ExpandableList.defaultRow.tsx, and ExpandableList.defaultRow.utils.ts files into ExpandableList.tsx and ExpandableList.utils.ts.
Replaced the domain-specific HypothesisExpandableItem default-row shape (signalCount, maxDeviation, cagg, domain, ttlLabel, relatedCount, needsAttention, deadlineNoteText, …) with a fully generic ExpandableListDefaultItem (metrics, progressPercent, secondaryProgressPercent, category, relatedLabel, banner, footerNoteText, …) so the built-in default row carries no business vocabulary. Existing per-field labels/values map onto metrics entries.
Added @signalos/circular-progress to registryDependencies (previously imported from a relative, undeclared path).

0.2.0

Merged @signalos/hypothesis-card into this widget as the built-in default row design: when renderCollapsed/renderExpanded are omitted, each item renders as a triage card (severity accent, confidence ring, TTL progress, optional "needs attention" banner) driven by the new HypothesisExpandableItem item shape. Added renderExpandedContent and onViewDetail props, used only by the default row design.
Supplying renderCollapsed/renderExpanded still fully replaces the row design, as before.
@signalos/hypothesis-card is removed; consumers pull @signalos/expandable-list with no render props for the same triage-card look.

0.1.0

Initial release as a standalone registry item (previously bundled with HypothesisCard, now split out to @signalos/hypothesis-card).
Renamed renderHeader/renderContent to renderCollapsed/renderExpanded to make the before/after-expansion contract explicit.
Supports loading, empty, and error states; controlled and uncontrolled expansion; single or multi-expand via allowMultiple.
