       .init(title: "title1", subtitle: "subtitle1"),
       .init(title: "title2", subtitle: "subtitle2", detail: "Detail"),
       .init(title: "title3"),
   ], style: .grouped)

override func awakeFromNib() {
    super.awakeFromNib()
    radioButtons = ALRadioGroup(items: [
        .init(title: "title1"),
        .init(title: "title2"),
        .init(title: "title3")
    ], style: .grouped)
    radioButtons.axis = .vertical
