Impose ComboBox like behavior on arbitrary control.
To create ComboX control, first create any kind of control and initialize it using Set function. After that, control will be stay visible only from the moment it is shown (via Show or Toggle) until it losses focus. You can optionally create trigger button for the ComboX control that will be used for showing and positioning of the control.
