如何在WPF中单列绘制多个“栈”

public class StackModel
{
    public ObservableCollection<string> Items { get; set; }

    public StackModel()
    {
        Items = new ObservableCollection<string>();
    }
}

<ItemsControl ItemsSource="{Binding Stacks}">
    <ItemsControl.ItemsPanel>
        <ItemsPanelTemplate>
            <StackPanel Orientation="Vertical"/>
        </ItemsPanelTemplate>
    </ItemsControl.ItemsPanel>
    <ItemsControl.ItemTemplate>
        <DataTemplate>
            <ItemsControl ItemsSource="{Binding Items}">
                <ItemsControl.ItemsPanel>
                    <ItemsPanelTemplate>
                        <StackPanel Orientation="Horizontal"/>
                    </ItemsPanelTemplate>
                </ItemsControl.ItemsPanel>
                <ItemsControl.ItemTemplate>
                    <DataTemplate>
                        <!-- 栈中元素的外观 -->
                        <TextBlock Text="{Binding}" Margin="5"/>
                    </DataTemplate>
                </ItemsControl.ItemTemplate>
            </ItemsControl>
        </DataTemplate>
    </ItemsControl.ItemTemplate>
</ItemsControl>

public class MainViewModel : INotifyPropertyChanged
{
    public ObservableCollection<StackModel> Stacks { get; set; }

    public MainViewModel()
    {
        Stacks = new ObservableCollection<StackModel>();

        // 添加示例数据
        var stack1 = new StackModel();
        stack1.Items.Add("Item 1");
        stack1.Items.Add("Item 2");
        Stacks.Add(stack1);

        var stack2 = new StackModel();
        stack2.Items.Add("Item 3");
        stack2.Items.Add("Item 4");
        Stacks.Add(stack2);
    }

    // INotifyPropertyChanged的实现...
}
