参考代码：

@Entry
@Component
struct Page {
  @State hideState: boolean = true
  controller: TextAreaController = new TextAreaController()
  foucsC = this.getUIContext().getFocusController()
  selectIndex = 0

  build() {
    Column() {
      Column() {
        Text('隐藏/显示面板')
          .onClick(() => {
            this.hideState = !this.hideState
            this.foucsC.clearFocus()
            this.foucsC.requestFocus('TextInput')
          })
      }.layoutWeight(1)
      .width('100%')
      .justifyContent(FlexAlign.Center)
      .backgroundColor(Color.Green)

      Column() {
        TextArea({ controller: this.controller })
          .id('TextInput')
        Column() {
          Text('菜单面板')
        }
        .width('100%')
        .height(300)
        .justifyContent(FlexAlign.Center)
        .backgroundColor(Color.Blue)
        .visibility(this.hideState ? Visibility.None : Visibility.Visible)
      }

    }.width('100%')
    .height('100%')
  }
}
