HarmonyOS select组件的下拉项怎么单独设置内容以及样式

目前Select不能自定义布局和样式，使用bindMenu来自定义菜单内容可以达到类似Select的效果，并且可以灵活控制选项样式自定义，示例demo如下：

class menu {
  value1: string = ''
  value2: string = ''
}
@Entry
@Component
struct Index {
  @State menuList: menu[] = [
    {value1: 'aa-1',value2: 'aa-2'},
    {value1: 'bb-1',value2: 'bb-2'},
    {value1: 'cc-1',value2: 'cc-2'},
    {value1: 'dd-1',value2: 'dd-2'},
    {value1: 'aa-1',value2: 'aa-2'},
    {value1: 'bb-1',value2: 'bb-2'},
    {value1: 'cc-1',value2: 'cc-2'},
    {value1: 'dd-1',value2: 'dd-2'},
    {value1: 'aa-1',value2: 'aa-2'},
    {value1: 'bb-1',value2: 'bb-2'},
    {value1: 'cc-1',value2: 'cc-2'},
    {value1: 'dd-1',value2: 'dd-2'}
  ]
  @State currentMenu: string = "1.0X"
  scroller: Scroller = new Scroller()
  @Builder
  MyMenu() {
    Column(){
      Scroll(this.scroller){
        Flex({ direction: FlexDirection.Column, alignItems: ItemAlign.Center }) {
          ForEach(this.menuList, (item: menu) => {
            Row(){
              Text(item.value1).height(32)
              Text(item.value2).height(32)
            }
            .onClick(() => {
              this.currentMenu = item.value1
            })

          })
        }
      }
      .scrollable(ScrollDirection.Vertical) // 滚动方向纵向
      .scrollBar(BarState.On) // 滚动条常驻显示
      .scrollBarColor(Color.Gray) // 滚动条颜色
      .scrollBarWidth(10) // 滚动条宽度
      .friction(0.6)
      .edgeEffect(EdgeEffect.None)
      .width(100)
      .backgroundColor(0x80ffffff)
    }
    .constraintSize({
      maxHeight: '30%'
    })
  }


  build() {
    Column() {
      Text(this.currentMenu)
        .fontSize(32)
        .bindMenu(this.MyMenu())
        .backgroundColor(Color.Gray)
        .width(100)
        .textAlign(TextAlign.Center)
    }
    .width('100%')
    .height("100%")
  }
}
