# sidebar:open embed event

> Emitted by Omni when a user clicks the mobile menu button.

This event is emitted when users click the mobile menu button to open the sidebar navigation.

Use this event to track when users interact with mobile navigation or to trigger custom behaviors in your embedding application when the sidebar is accessed.

<Note>
  This event is informational only. The sidebar popover will still open within the embedded iframe regardless of how the parent application handles this event.
</Note>

## Payload

This event carries an empty payload and serves as a notification signal only.

```json theme={null}
{}
```

## Example

When a user clicks the mobile menu button, Omni emits:

```json theme={null}
{
  "name": "sidebar:open",
  "payload": {}
}
```
