## Locking orientation
Orientation can be locked either in the layout level, or across the app via default options. You can declare orientations you'd like your app to support in default options.

<Tabs
  defaultValue="defaultOptions"
  values={[
    { label: 'Locking orientation in default options', value: 'defaultOptions', },
    { label: 'Locking root layout orientation', value: 'root', },
    { label: 'Showing landscape modal', value: 'modal', }
  ]
}>
<TabItem value="defaultOptions">

Setting orientation in default options will affect all screens in all hierarchy levels. It's still possible to override orientation for specific screens.

```js
Navigation.setDefaultOptions({
  layout: {
    orientation: ['portrait']
  }
});
```

</TabItem>
<TabItem value="modal">

The following example demonstrates how to show a modal in landscape orientation.

```js
Navigation.showModal({
  component: {
    name: 'VideoPlayer'
    options: {
      layout: {
        orientation: ['landscape']
      }
    }
  }
});
```

</TabItem>
<TabItem value="root">

Applying orientation in the root level will affect all screens in the root hierarchy level. It **will not** apply to modals.

```js
Navigation.setRoot({
  root: {
    bottomTabs: {
      options: {
        layout: {
          orientation: ['portrait']
        }
      },
      children: [
        ...
      ]
    }
  }
});
```

</TabItem>
</Tabs>

## Changing orientation dynamically

Changing orientation dynamically through `Navigation.mergeOption()` is supported only on Android.

```js
Navigation.mergeOptions(this.props.componentId, {
  layout: {
    orientation: ['landscape']
  }
});
```
