MenuItem Click

Hi

On your WPF demo, when a menuitem that has child menuitems is clicked (not using it's header, just on the name/icon), the child items are shown.

This saves this user having to click on the outer circle header which is handy.

How's this done, I can't get this to happen?

I've made the parent menuitem CanUserSelect="True", do I need to wire up some code also??

Thanks in advance.
