# DmsListElement

> A UI element that displays a dms list.

## Overview

A UI element that displays a dms list.

## Usage

### Basic usage

```typescript theme={null}
// Create the element
const element = session.createElement("dms-list-element", {
  onReady: (element) => {
    console.log("Dms list element is ready");
  },
});

// Mount it to a container
element.mount("#dms-list-container");
```

### Listening to events

```typescript theme={null}
const element = session.createElement("dms-list-element", {});

element.on("ready", () => {
  console.log("Dms list element is ready");
});

element.on("channelSelected", (ev) => {
  console.log("Channel selected:", ev.detail.id);
});

element.mount("#dms-list-container");
```

```typescript theme={null}
const element = session.createElement("dms-list-element", {
  onReady: (element) => {
    console.log("Dms list element is ready");
  },
});
```

## Events

Events emitted by the DmListElement.

Listen to these events using the `on()` method or by passing callback functions in the options.

### `error`

Emitted when an error occurs during element initialization or operation.

**Callback signature:** (error: `unknown`) => void

### `ready`

Emitted when the element has finished loading and is ready for user interaction.

**Callback signature:** (element: `DmsListElement`) => void

### `optionsUpdated`

Emitted when the element's options are updated via `updateOptions()`.

**Callback signature:** (options: [`DmsListElementOptions`](#dmslistelementoptions)) => void

### `snapshot`

Emitted when the element's internal state changes.

**Callback signature:** (snapshot: [`DmsListElementSnapshot`](#dmslistelementsnapshot)) => void

### `channelSelected`

Emitted when the user clicks a channel.

**Callback signature:** (ev: `CustomEvent`\<\{ id: `string`; }>) => void

## Methods

### `mount(container)`

Mount the element to a DOM container.

The container must be an empty element. The element will be appended as a child.
If the element is already mounted, this method will log a warning and return.

| Parameter   | Type                              | Description                                               |
| ----------- | --------------------------------- | --------------------------------------------------------- |
| `container` | `HTMLElement` \| `#$\{`string`\}` | The container element or a CSS selector starting with '#' |

```typescript theme={null}
// Using a selector
element.mount("#my-container");

// Using an element reference
const container = document.getElementById("my-container");
element.mount(container);
```

### `unmount()`

Remove the element from the DOM and clean up all event listeners.

After unmounting, the element instance should not be reused.
Create a new element instance if you need to mount again.

```typescript theme={null}
// Unmount when done
element.unmount();

// Commonly used in event handlers
element.on("complete", () => {
  element.unmount();
});
```

### `updateOptions(options)`

Update the element's configuration options after creation.

Only the provided options will be updated; other options remain unchanged.
The element will re-render with the new options.

| Parameter | Type                                                          | Description                                      |
| --------- | ------------------------------------------------------------- | ------------------------------------------------ |
| `options` | `Partial`\<[`DmsListElementOptions`](#dmslistelementoptions)> | Partial options object with the values to update |

```typescript theme={null}
// Update a single option
element.updateOptions({
  onComplete: (ev) => {
    console.log("New handler!");
  },
});
```

### `getSnapshot()`

Get the current state snapshot of the element.

The snapshot contains the element's current internal state, such as
loading status, form values, or other element-specific data.

**Returns:** [`DmsListElementSnapshot`](#dmslistelementsnapshot)

```typescript theme={null}
const snapshot = element.getSnapshot();
console.log("Current state:", snapshot.state);

// Or listen for changes
element.on("snapshot", (snapshot) => {
  console.log("State changed:", snapshot);
});
```

## Styling

Customize this element with `appearance.classes`. See the [styling reference](/sdk/elements/styling-reference) for the full list of stable class names and example snippets.

### DmsListElementSnapshot

Represents the current state of the DmsListElement.
