    var body: some View {
        Menu {
            Picker(selection: $selectionVariable, label: Text("")) {
                ForEach(sampleDict.sorted(by: <), id: \.key) { base, name in
                    Text(name)
                }
            }
        }
        label: {
            Text("Eingaben im \(sampleDict[selectionVariable] ?? "")")
        }
    }
}
