Graeme, I don't know much about fpGui. I will look at fpGui.

You are right. But I stripped down the component. Removed a lot of code 
to make it easier to focus on the essential parts of this component. 
What I need is a way to:
- View the dropdown panel but the focus must stay in the edit control
- The panel must be on top of the window and stay on top
- The window must keep the focus (stay active window)
- The panel may display itself over the border of the window
- Shadow is nice but not needed
- Buttons in the edit control is nice but they can also be on the right 
site near the edit.
