struct MenuView: View {
    @State private var selectedItem: String = ""
    
    var body: some View {
        ScrollView(.horizontal) {
            HStack {
                ForEach(menuItems, id: \.self) { item in
                    Text(item)
                        .font(.title)
                        .padding()
                        .background(selectedItem == item ? Color.blue : Color.clear)
                        .foregroundColor(selectedItem == item ? Color.white : Color.black)
                        .onTapGesture {
                            selectedItem = item
                        }
                }
            }
