## Attributes

| Name        | Type                       | Description                                        |
| ---------- | ---------------------------- | ------------------------------------------ |
| visibility | [Visibility](ts-appendix-enums.md#visibility) | Whether the component is visible. Note that even if a component is invisible, it still needs to be re-created when the page is refreshed. Therefore, you are advised to use [conditional rendering](../../quick-start/arkts-rendering-control-ifelse.md) instead under scenarios where consistently high performance is required.<br>Default value: **Visibility.Visible**<br>Since API version 9, this API is supported in ArkTS widgets.|


## Example

```ts
// xxx.ets
@Entry
@Component
struct VisibilityExample {
  build() {
    Column() {
      Column() {
        // The component is hidden and does not take up space in the layout.
        Text('None').fontSize(9).width('90%').fontColor(0xCCCCCC)
        Row().visibility(Visibility.None).width('90%').height(80).backgroundColor(0xAFEEEE)

        // The component is hidden but takes up space in the layout.
        Text('Hidden').fontSize(9).width('90%').fontColor(0xCCCCCC)
        Row().visibility(Visibility.Hidden).width('90%').height(80).backgroundColor(0xAFEEEE)

        // The component is visible, which is the default display mode.
        Text('Visible').fontSize(9).width('90%').fontColor(0xCCCCCC)
        Row().visibility(Visibility.Visible).width('90%').height(80).backgroundColor(0xAFEEEE)
      }.width('90%').border({ width: 1 })
    }.width('100%').margin({ top: 5 })
  }
}
```
