WPF Accordion - Bind to Data (HierarchicalDataTemplate)

This example binds the WPF Accordion Control to data (MyData.Categories) and uses System.Windows.HierarchicalDataTemplate to present accordion items.

<dxa:AccordionControl x:Name="accordion" SelectionUnit="SubItem" 
        ItemsSource="{Binding MyData.Categories }" SelectedItem="{Binding SelectedItem}">
    <dxa:AccordionControl.ItemTemplate>
        <HierarchicalDataTemplate DataType="{x:Type local:Category}" ItemsSource="{Binding Items}">
            <TextBlock Text="{Binding CategoryName}"/>
            <HierarchicalDataTemplate.ItemTemplate>
                <DataTemplate DataType="{x:Type local:Item}">
                    <TextBlock Text="{Binding ItemName}"/>
                </DataTemplate>
            </HierarchicalDataTemplate.ItemTemplate>
        </HierarchicalDataTemplate>
    </dxa:AccordionControl.ItemTemplate>
</dxa:AccordionControl>
