# NavDestination

**NavDestination** is the root container of a destination page and represents the content area of the [Navigation](ts-basic-components-navigation.md) component.

> **NOTE**
>
> - This component is supported since API version 9. Updates will be marked with a superscript to indicate their earliest API version.
>
> - Since API version 11, this component supports the safe area attribute by default, with the default attribute value being **expandSafeArea([SafeAreaType.SYSTEM], [SafeAreaEdge.TOP, SafeAreaEdge.BOTTOM])**. You can override this attribute to change the default behavior. In earlier versions, you need to use the [expandSafeArea](ts-universal-attributes-expand-safe-area.md) attribute to implement the safe area feature.
>
> - The **NavDestination** component must be used in conjunction with the **Navigation** component to act as the root node for the navigation destination page. When used alone, it can only function as a standard container component and does not possess any routing-related attributes or capabilities.
>
> - If the lifecycle of a page in the middle of the navigation stack changes, the lifecycle of the destination page at the top of the stack before the transition (**onWillShow**, **onShown**, **onHidden**, **onWillDisappear**) and the lifecycle of the destination page after the transition (**onWillShow**, **onShown**, **onHidden**, **onWillDisappear**) are both triggered at the end.
>
> - If no main title or subtitle is set for **NavDestination** and there is no back button, the title bar is not displayed.

## Child Components

This way, scrolling in the scrollable container triggers the display and hide animations of the title bar and toolbar of all **NavDestination** components that are bound to it – scrolling up triggers the hide animation, and scrolling down triggers the show animation. A single **NavDestination** component can be bound to multiple scrollable containers, and a single scrollable container can be bound to multiple **NavDestination** components. For details, see [Example 1](#example-1-linking-the-title-bar-and-toolbar-with-scrollable-components).

### Example 3: Setting System Transition Animations for the NavDestination Component

The following example demonstrates how to set system transition animations using [systemTransition](#systemtransition14) with **Fade**, **Explode**, **SlideBottom**, and **SlideRight** effects.

```ts
@Entry
@Component
struct NavDestinationSystemTransition {
  @Provide stack: NavPathStack = new NavPathStack()
  @Provide homePageTransitionType: NavigationSystemTransitionType = NavigationSystemTransitionType.DEFAULT;

  @Builder
  pageMap(name: string) {
    if (name === 'Fade') {
      Fade()
    } else if (name === 'Explode') {
      Explode()
    } else if (name === 'SlideRight') {
      SlideRight()
    } else if (name === 'SlideBottom') {
      SlideBottom()
    } else {
      Dest()
    }
  }

  aboutToAppear(): void {
    this.stack.pushPath({name: 'Dest'})
  }

### Example 4: Configuring Display Orientation and Status Bar and Navigation Bar Visibility

This example demonstrates how to configure each **NavDestination** component with specific display orientations and control the visibility of the status bar and navigation bar.

```ts
import { window } from '@kit.ArkUI';

@Component
struct PortraitPage {
  private stack: NavPathStack | undefined = undefined;
  build() {
    NavDestination() {
      Stack({alignContent: Alignment.Center}) {
        Button('push LANDSCAPE page').onClick(() => {
          this.stack?.pushPath({name: 'landscape'})
        })
      }.width('100%').height('100%')
    }
    .width('100%').height('100%')
    .title('PortraitPage')
    .preferredOrientation(window.Orientation.PORTRAIT) // Portrait orientation.
    .enableStatusBar (true) // Show the status bar.
    .enableNavigationIndicator(true) // Show the navigation bar.
    .backgroundColor('#ffbaece9')
    .onReady((ctx: NavDestinationContext) => {
      this.stack = ctx.pathStack;
    })
  }
}

@Component
struct LandscapePage {
  private stack: NavPathStack | undefined = undefined;
  build() {
    NavDestination() {
      Stack({alignContent: Alignment.Center}) {
        Button('push PORTRAIT page').onClick(() => {
          this.stack?.pushPath({name: 'portrait'})
        })
      }.width('100%').height('100%')
    }
    .width('100%').height('100%')
    .title('LandscapePage')
    .preferredOrientation(window.Orientation.LANDSCAPE) // Landscape orientation.
    .enableStatusBar(false) // Hide the status bar.
    .enableNavigationIndicator(false) // Hide the navigation bar.
    .backgroundColor('#ffecb8b8')
    .ignoreLayoutSafeArea([LayoutSafeAreaType.SYSTEM], [LayoutSafeAreaEdge.TOP, LayoutSafeAreaEdge.BOTTOM])
    .onReady((ctx: NavDestinationContext) => {
      this.stack = ctx.pathStack;
    })
  }
}

@Entry
@Component
struct ExamplePage {
  private stack: NavPathStack = new NavPathStack();

  aboutToAppear(): void {
    this.stack.pushPath({name: "portrait"})
  }

  @Builder
  MyPageMap(name: string) {
    if (name === 'portrait') {
      PortraitPage()
    } else {
      LandscapePage()
    }
  }

  build() {
    Navigation(this.stack) {
    }
    .width('100%')
    .height('100%')
    .hideNavBar(true)
    .navDestination(this.MyPageMap)
  }
}
```
