panel

I'd like to create a dropdown panel in WPF the acts like a ComboBox/Expander hybrid. I'm currently using an Expander but it pushes the the controls underneath it down when it expands.

I simply want it to act like a ComboBox and overlay it's dropdown. I've looked at using Popups but they don't move with the underlying window if it's moved.

So, I've concluded that the closest control to my needs is a ComboBox with allows me to put a Grid or StackPanel into its dropdown area.

Any ideas how to achieve this?
