Dear .all

I have a content view with a.... okay let the code spreak for it selfs.

`

 struct ContentView: View {
    // .....
    var body: some View {
        HStack{
            NavigationView {

                SideBarView_HWS().frame(minWidth: 200,idealWidth: 250,maxWidth: 260, maxHeight: .infinity )

                BodyInfoStartView()

            } //  .frame(minWidth: 200,idealWidth: 250,maxWidth: 260, maxHeight: .infinity ) <<< this isn't working
        }
    }
 }

 struct SideBarView_HWS: View {
    //....
    @State private var clientExpanded: Bool = true
    @State var selection: String?

    var body: some View {
        VStack  {
            List(selection: $selection) {
                ForEach(agendaItems, id: \.self) { string in
                        NavigationLink(destination: AgendaFrameView(description: string)) {
                            Text(string)
                        }
                    }
                NavBarSection2()
            }
            .listStyle(SidebarListStyle())

            Divider()

            DisclosureGroup("Show some Text", isExpanded: $clientExpanded) {
                Text("Some Text...")
                    .padding()
                Text("Hello, Mars!").padding()
            }
            .padding()

            Divider()

            Text( "<Moonwalker is talking>")
        }
    }
 }

`

My goal is; I need to have both, the sideBar and the NavigationView, having the same maxWidth constraints. If I add a .frame to the navigationView the NavigationView and SideBar dissapears. If I us the .frame with Width constraints only to the SideBar then only the sideBar get shrinked but the NavigationView stays to its too width size.

How can I solve this? Its for iPadOS ( not iPhone )
