我有三个类，我希望在树视图中表示

public class ConfiguratorObjectViewModel
{
    public string Name { get; set; }
    
    public string Id { get; set; }
        
    public string ParentId { get; set; }
    
    public ObservableCollection<ConfiguratorAttributeViewModel> Attributes { get; set; } 
        
    public ObservableCollection<ConfiguratorObjectFamilyViewModel> Children { get; set; }   
}

public class ConfiguratorObjectFamilyViewModel
{
    public string Name { get; set; }
    
    public string Id { get; set; }
        
    public string ParentId { get; set; }
        
    public ObservableCollection<ConfiguratorObjectViewModel> ConfiguratorObjects { get; set; }  
}

public class ConfiguratorAttributeViewModel
{
    public string Name { get; set; }
    
    public string Id { get; set; }
        
    public string ParentId { get; set; }    
}

这是我的treeview模板

<TreeView ItemsSource="{Binding RootObject}" >
    <TreeView.Resources>
    
    <HierarchicalDataTemplate DataType="{x:Type local:ConfiguratorObjectFamilyViewModel}" ItemsSource="{Binding ConfiguratorObjects}">
            <local:ConfiguratorObjectTreeItem  />
        </HierarchicalDataTemplate>
    
     <HierarchicalDataTemplate DataType="{x:Type local:ConfiguratorObjectViewModel}" ItemsSource="{Binding }" Children>
            <local:ConfiguratorObjectTreeItem  />
        </HierarchicalDataTemplate>   

    </TreeView.Resources>

</TreeView>

这个模板给了我所有的ConfiguratorObjectFamily和所有的ConfoguratorObject项目。我如何扩展它，使ConfiguratorAttribute项应该包含在树中？
我试过通过添加以下组合来扩展模板，但无济于事...

<HierarchicalDataTemplate DataType="{x:Type local:ConfiguratorAttributeViewModel}" ItemsSource="{Binding Attributes}" >
    <local:ConfiguratorObjectTreeItem  />
</HierarchicalDataTemplate>

<DataTemplate DataType="{x:Type local:ConfiguratorAttributeViewModel}" >
    <local:ConfiguratorObjectTreeItem  />
</DataTemplate>

请注意，ConfiguratorAttributeViewModel不是层次结构
