Word style context menu in WPF?

What controls would be most suitable for creating a complex context menu, similar what you see in Windows Word. Should it be pop up, tooltip, or context menu or a transparent window?

What you think would be the best control to start开发者_开发技巧 with?

I'd start with a ContextMenu, since that is the behaviour you want. Unlike a ToolTip that won't automatically disappear after a few seconds, and it is already set up to by a collection of MenuItems.
