[Lazarus] How to hide the dropdown button of ComboBox

[silvioprog]

Hi,

Is it possible to hide the dropdown button of the ComboBox? (GTK and Win)

I'm trying to create an "AutoCompleteEdit". Eg:

I need this: http://imagebin.org/172239

But the ComboBox don't shows the list when Style is csSimple.

Thx.
