+---
+
+# List
+
+The list family provides accessible, keyboard-navigable list containers and
+item variants. Pick the container based on semantics, then the item based on
+interactivity.
+
+## Containers
+
+### `<ha-list-base>`
+
+A styled container with roving-tabindex keyboard navigation. Host role is
+`list`. Children should be `<ha-list-item-*>`. Arrow keys rove focus;
+Home/End jump to the first/last enabled item; Enter/Space activates the
+focused item.
+
+**Attributes**
+
+| Name         | Type    | Default | Description                    |
+| ------------ | ------- | ------- | ------------------------------ |
+| `wrap-focus` | Boolean | `false` | Arrow keys wrap past the ends. |
+| `aria-label` | String  | —       | Accessible name.               |
+
+**Events**
+
+- `ha-list-activated` — Enter/Space on a focused item. Detail
+  `{ index: number, item: HaListItemBase }`.
+
+**Methods**
+
+- `focus()` — focus the active item (or the first focusable one).
+- `focusItemAtIndex(index)` — make the item at `index` active and focus it.
+- `getActiveItemIndex()` — current active index, or `-1`.
+- `setActiveItemIndex(index, focusItem?)` — move the active index without
+  necessarily focusing.
+- `updateListItems()` — re-discover slotted items (called automatically on
+  slotchange).
+
+**CSS parts**
+
+- `base` — the outer `<div role="list">`.
+
+**CSS custom properties**
+
+- `--ha-list-gap` — spacing between items. Defaults to `0`.
+- `--ha-list-padding` — padding around the list. Defaults to `0`.
+
+### `<ha-list-selectable>`
+
+Selectable list. Extends `ha-list-base`. Host role is `listbox`; items must be
+`<ha-list-item-option>` (role `option`). Set `multi` for multi-select; the
+host reflects `aria-multiselectable`.
+
+**Attributes**
+
+| Name    | Type    | Default | Description                            |
+| ------- | ------- | ------- | -------------------------------------- |
+| `multi` | Boolean | `false` | Allow multiple options to be selected. |
+
+**Events**
+
+- `ha-list-selected` — selection changed. Detail
+  `{ index: number | Set<number>, diff: { added: Set<number>, removed: Set<number> } }`.
+  `index` is a `number` in single mode (`-1` when nothing selected) and a
+  `Set<number>` in multi mode.
+
+**Methods / getters**
+
+- `selected` (getter) — current selection (`number` or `Set<number>`).
+- `selectedItems` (getter) — selected `HaListItemOption` elements, in index
+  order.
+- `setSelected(indices)` — replace the entire selection.
+- `select(index)` — add `index` to the selection (replaces in single mode).
+- `toggle(index, force?)` — toggle a single index, or force on/off.
+- `clearSelection()` — clear all.
+
+### `<ha-list-nav>`
+
+Same as `ha-list-base`, but wrapped in a `<nav>` landmark
+(`<nav><div role="list">…</div></nav>`). Use `aria-label` to name the
+landmark — the value is forwarded to the inner `<nav>`. Items should be
+`<ha-list-item-button>` with an `href`.
+
+**CSS parts**
+
+- `nav` — the `<nav>` wrapper.
+- `base` — the inner `<div role="list">`.
+
+## Items
+
+All items inherit from `ha-row-item`, which provides the row layout and the
+shared slots/attributes below.
+
+### Shared row layout (`ha-row-item`)
+
+**Slots**
+
+- `start` — leading container (icon/avatar).
+- `end` — trailing container (meta/chevron).
+- `headline` — primary text (overrides the `headline` attribute).
+- `supporting-text` — secondary text (overrides the `supporting-text` attribute).
+- `content` — escape hatch: replaces the entire middle column.
+
+**Attributes**
+
+| Name              | Type    | Default | Description                             |
+| ----------------- | ------- | ------- | --------------------------------------- |
+| `headline`        | String  | —       | Primary text. Overridden by the slot.   |
+| `supporting-text` | String  | —       | Secondary text. Overridden by the slot. |
+| `disabled`        | Boolean | `false` | Dims the row and blocks pointer events. |
+
+**CSS parts**
+
+`base`, `start`, `content`, `headline`, `supporting-text`, `end`.
+
+**CSS custom properties**
+
+- `--ha-row-item-padding-block` — vertical padding.
+- `--ha-row-item-padding-inline` — horizontal padding.
+- `--ha-row-item-gap` — gap between `start`, `content`, and `end`.
+- `--ha-row-item-min-height` — minimum row height (default `48px`).
+
+### `<ha-list-item-base>`
+
+Non-interactive list row. Host role is `listitem`. Inherits everything from
+`ha-row-item`.
+
+**Attributes**
+
+- `interactive` (Boolean, default `false`) — opt this row into the parent
+  list's roving tabindex. Useful for sortable rows that need keyboard focus
+  but no click action. Interactive subclasses set this automatically.
+
+**CSS custom properties**
+
+- `--ha-list-item-focus-radius` — focus outline border-radius.
+- `--ha-list-item-focus-width` — focus outline width (steady state).
+- `--ha-list-item-focus-width-start` — focus outline width at the start of
+  the focus-in animation.
+- `--ha-list-item-focus-offset` — focus outline offset.
+- `--ha-list-item-focus-background` — background color on keyboard focus.
+
+### `<ha-list-item-button>`
+
+Interactive row. Renders an inner `<a>` when `href` is set, otherwise a
+`<button>`. The full row is the hit target. When placed inside a list using
+roving tabindex, the host is the tab stop and the inner element carries
+`tabindex="-1"`.
+
+**Attributes**
+
+- `href` (String) — when set, renders an `<a>` instead of a `<button>`.
+- `target` (String) — anchor `target` (requires `href`).
+- `rel` (String) — anchor `rel` (requires `href`).
+- `download` (String) — anchor `download` (requires `href`).
+
+**CSS parts**
+
+- `ripple` — the ripple effect element.
+
+### `<ha-list-item-option>`
+
+Selectable row. Host role is `option`; reflects `aria-selected`. Designed to
+sit inside `<ha-list-selectable>`, which owns selection state and toggles
+`selected` on this item — the option itself does not fire selection events.
+
+**Attributes**
+
+- `selected` (Boolean, default `false`, reflected) — set by the parent
+  `ha-list-selectable`.
+- `value` (String) — value identifying the option.
+- `appearance` (`"line"` | `"checkbox"`, default `"line"`) — `"line"`
+  highlights the row; `"checkbox"` renders a decorative `<ha-checkbox>`.
+- `selection-position` (`"start"` | `"end"`, default `"start"`) — side the
+  checkbox sits on when `appearance="checkbox"`.
+
+**CSS parts**
+
+- `checkbox` — wrapper around the `<ha-checkbox>` when `appearance="checkbox"`.
+- `ripple` — the ripple effect element.
+
+**CSS custom properties**
+
+- `--ha-list-item-selected-background` — background color when selected
+  (`appearance="line"`).
