    Hello,

    You need to define several levels of nesting item templates as follows:

            <igTree:XamWebTree x:Name="TestXamWebTree" ItemsSource="{Binding}">
            <!--THE ROOT LEVEL ITEM TEMPLATE IS HIERARCHICAL-->
            <igTree:XamWebTree.HierarchicalItemTemplate>
                <ig:HierarchicalDataTemplate ItemsSource="{Binding ChildNodes}">
                    <!--THE DATA TEMPLATE FOR THE ROOT LEVEL ITEM FOLLOWS-->
                    <DataTemplate>
                        <TextBlock Text="{Binding Name}"/>
                    </DataTemplate>
                    <!--THE FIRST LEVEL CHILD ITEM TEMPLATE IS HIERARCHICAL-->
                    <ig:HierarchicalDataTemplate.HierarchicalItemTemplate>
                        <ig:HierarchicalDataTemplate ItemsSource="{Binding ChildNodes}">
                            <!--THE DATA TEMPLATE FOR THE FIRST LEVEL CHILD ITEM FOLLOWS-->
                            <DataTemplate>
                                <TextBlock Text="{Binding Name}"/>
                            </DataTemplate>
                            <!--THE SECOND LEVEL CHILD ITEM TEMPLATE IS NON-HIERARCHICAL-->
                            <ig:HierarchicalDataTemplate.ItemTemplate>
                                <!--THE DATA TEMPLATE FOR THE SECOND LEVEL CHILD ITEM FOLLOWS-->
                                <DataTemplate>
                                    <TextBlock Text="{Binding Name}"/>
                                </DataTemplate>
                            </ig:HierarchicalDataTemplate.ItemTemplate>
                        </ig:HierarchicalDataTemplate>
                    </ig:HierarchicalDataTemplate.HierarchicalItemTemplate>
                </ig:HierarchicalDataTemplate>
            </igTree:XamWebTree.HierarchicalItemTemplate>
        </igTree:XamWebTree>
