WPF XAML - MenuItem with ItemSource Elements and Submenus

Question

I have a MenuItem in the context menu that I want to generate sub MenuItems for each item in the list using ItemSource. Each of these generated items must also have the MenuItems Active (checkable), Edit, and Delete submenus.

Custom Messages
    -Custom Message 1
           -Active 
           -Edit
           -Delete
    -Custom Message 2
           -Active 
           -Edit
           -Delete
    -Custom Message 3
           -Active 
           -Edit
           -Delete

The following XAML partially works:

<MenuItem Header="Custom Messages" Visibility="{Binding Path=HasCustomMessages, Converter={StaticResource BVC}}" ItemsSource="{Binding Path=CustomMessages}" DisplayMemberPath="Description">
    <MenuItem.ItemContainerStyle>
        <Style TargetType="MenuItem">
            <Setter Property="ItemsSource">
                <Setter.Value>
                    <x:Array Type="FrameworkElement">
                        <MenuItem Header="Active" IsCheckable="True" IsChecked="{Binding Path=Active}"></MenuItem>
                        <Separator></Separator>
                        <MenuItem Header="Edit" Name="EditCustomMessageButton" Click="EditCustomMessageButton_Click" Style="{x:Null}"></MenuItem>
                        <MenuItem Header="Delete" Name="DeleteCustomMessageButton" Click="DeleteCustomMessageButton_Click" Style="{x:Null}"></MenuItem>
                    </x:Array>
                </Setter.Value>
            </Setter>
        </Style>
    </MenuItem.ItemContainerStyle>                       
</MenuItem>
<MenuItem Header="Add Custom Message" Name="AddCustomMessageButtton" Click="AddCustomMessageButtton_Click"></MenuItem>
<Separator></Separator>
<MenuItem Header="Delete" Name="DeleteButton" Click="DeleteButton_Click"></MenuItem>

However, there are two problems:

• Editing and deleting seem to behave in a reducing way, since both of them have submenus and then drop and exclude when they freeze:

• ItemSource = "{x: Null}" " ", , . "" , "" "" "", "" , "" "" ( ).
