WPF Submenu ItemsPanel

Question

I want to show the menu items in multiple Columns..

I want to use WrapPanels for menus

below code works well for first level, but when opening sub menus or sub menus of sub menus , its shows as ordinary list.

What can be done to override the default behavior.

note: I am using Itemssource to bind menu items (Objects of my own Class), so i can't give nested Item Styles.

<Style TargetType="{x:Type MenuItem}"  BasedOn="{StaticResource {x:Type MenuItem}}">
   ....
   <Setter Property="ItemsSource" Value="{Binding Children}"/>
   ....
   <Setter Property="ItemsPanel">
         <Setter.Value>
             <ItemsPanelTemplate>
                   <WrapPanel MaxHeight="300" Orientation="Vertical"/>
             </ItemsPanelTemplate>
         </Setter.Value>
    </Setter>
     ....
</Style>

You can bind to any level

          <Style TargetType="MenuItem">
                <Setter Property="ItemsSource" Value="{Binding Children}"/>
                    <Setter Property="ItemsPanel">
                        <Setter.Value>
                            <ItemsPanelTemplate>
                                <WrapPanel MaxHeight="300" Orientation="Vertical"/>
                            </ItemsPanelTemplate>
                        </Setter.Value>
                    </Setter>
                    <Setter Property="ItemContainerStyle">
                    <Setter.Value>
                            <Style TargetType="MenuItem">
                                <Setter Property="ItemsSource" Value="{Binding Children}"/>
                                <Setter Property="ItemsPanel">
                                    <Setter.Value>
                                        <ItemsPanelTemplate>
                                            <WrapPanel MaxHeight="300" Orientation="Vertical"/>
                                        </ItemsPanelTemplate>
                                    </Setter.Value>
                                </Setter>
                                <Setter Property="ItemContainerStyle">
                                    <Setter.Value>
                                        <Style TargetType="MenuItem">
                                            <Setter Property="ItemsSource" Value="{Binding Children}"/>
                                            <Setter Property="ItemsPanel">
                                                <Setter.Value>
                                                    <ItemsPanelTemplate>
                                                        <WrapPanel MaxHeight="300" Orientation="Vertical"/>
                                                    </ItemsPanelTemplate>
                                                </Setter.Value>
                                            </Setter>
                                        </Style>
                                    </Setter.Value>
                                </Setter>
