Multilevel WPF Treeview with Binding

I just want to create a treeview using binding in wpf. I have a class (ClassRoot) as root and I have 3 properties in root class of type ClassA, ClassB, ClassC like the following,

class ClassRoot
{
    public ClassA propClassA { get; set; }
    public ClassB propClassB { get; set; }
    public ClassC propClassC { get; set; }
}

each class having its own properties. It may have properties of type List or Enum, etc., like below,

class ClassA
{
   public string Name { get; set; }

   //Here ListOfValues is an enum
   public ListOfValues listValues { get; set; }

   public List<string> stringValues { get; set; }
}

like the above class, ClassB and ClassC also having the same structure. I want to show this in WPF treeview like the following,

each properties should be editable, properties of type List or Enum should be represented as ComboBox in treeview. I can use hierarchical data template, but I'm confusing to implement this multi level hierarchy. How can I proceed with this?
Thank you,

use HierarchicalDataTemplate 

    <HierarchicalDataTemplate DataType    = "{x:Type src:ClassRoot}"
                              ItemsSource = "{Binding Path=Divisions}">
      <TextBlock Text="{Binding Path=Name}"/>
    </HierarchicalDataTemplate>

    <HierarchicalDataTemplate DataType    = "{x:Type src:ClassA}"
                              ItemsSource = "{Binding Path=Teams}">
      <TextBlock Text="{Binding Path=Name}"/>
    </HierarchicalDataTemplate>

    <HierarchicalDataTemplate DataType    = "{x:Type src:ClassB}"
                              ItemsSource = "{Binding Path=Teams}">
      <TextBlock Text="{Binding Path=Name}"/>
    </HierarchicalDataTemplate>
