### `ExpandableListProps`

| Prop | Type | Required | Default | Description |
| --- | --- | --- | --- | --- |
| `items` | `readonly TItem[]` | yes | - |  |
| `renderCollapsed` | `((item: TItem, index: number, expanded: boolean) => ReactNode) \| undefined` | no | - | 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` | no | - | 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` | no | - | Extra content appended to the expanded body, below the description. Only used by the built-in default row design. |
| `onViewDetail` | `((item: TItem) => void) \| undefined` | no | - | Shows a "View detail" action row and fires on click. Only used by the built-in default row design. |
| `variant` | `ExpandableListVariant \| undefined` | no | - |  |
| `allowMultiple` | `boolean \| undefined` | no | - | Allow more than one item to be expanded at a time.  Defaults to false (accordion behavior). |
| `disableCollapse` | `boolean \| undefined` | no | `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` | no | - | Controlled expanded item ids. Provide together with `onExpandedChange` to fully control expansion state. |
| `defaultExpandedIds` | `readonly string[] \| undefined` | no | - | Initial expanded item ids for uncontrolled usage. |
| `onExpandedChange` | `((expandedIds: string[]) => void) \| undefined` | no | - |  |

## 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.


## 0.3.6
- lint issue fix 
## 0.3.5

- Types update for `events` 
## 0.3.3

- Added disabled state for collapse. 

## 0.3.2

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

## 0.3.1

- 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`.
