    // For 2 or more views
    init<Views>(@ViewBuilder content: TupleContent<Views>) {
        views = ViewExtractor.getViews(from: content)
    }
    
    // For 0 or 1 view
    init<Content: View>(@ViewBuilder content: NormalContent<Content>) {
        views = ViewExtractor.getViews(from: content)
    }
    
    var body: some View {
        VStack(spacing: 0) {
            ForEach(views.indices) { index in
                if index != 0 {
                    Divider()
                }
                
                views[index]
