Creates a drop list user control on the user window specified by windowID.

A drop list enables the user to select from a set of list of items, with the list dynamically displaying when the user clicks an arrow button.

The control is initially placed in the top-left corner of the user window, and must be placed by using the -pos option, or by using the setControlPos command.

The height of the "edit" portion of the drop list is always fixed, regardless of the height specified using the -pos option or setControlPos command. The height of the list portion of the drop list is specified by the height of the control.

The command returns the Control ID of the user control, which should be saved for later operations on the control.
