SwiftUI -当每个列表视图的内容依赖于前一个列表视图中的选择时，最好的方法？

struct ContentView: View {
    @State private var selectedItem: String = ""
    
    var body: some View {
        VStack {
            List(["Option 1", "Option 2", "Option 3"], id: \.self) { option in
                Button(action: {
                    selectedItem = option
                }) {
                    Text(option)
                }
            }
            
            if selectedItem == "Option 1" {
                List(["Suboption 1", "Suboption 2"], id: \.self) { suboption in
                    Text(suboption)
                }
            } else if selectedItem == "Option 2" {
                List(["Suboption 3", "Suboption 4"], id: \.self) { suboption in
                    Text(suboption)
                }
            } else if selectedItem == "Option 3" {
                List(["Suboption 5", "Suboption 6"], id: \.self) { suboption in
                    Text(suboption)
                }
            }
        }
    }
}
