No, the size is fixed by the Windows DLL based the font size being used. To
change this is a lot of work that is probably not justified. You have to do
your own drawing of the control.

You could try something like this ...

--------------
sequence ddKeys, ddCodes
ddKeys = {"2% 10 Net 30", "3% 10 Net 60", "5% 15 Net 90" }
ddCodes= { "N3"         , "N6"          , "N9"           }

procedure Init_myDropDown()
    eraseItems(myDropDown)
    addItem(myDropDown, ddKeys)
end procedure

procedure myDropDown_Click()
    sequence pick
    integer what

    pick = getItem(myDropdown, 0)
    if length(pick) != 0 then
        what = find(pick, ddKeys)
        if what != 0 then
            theField = ddCodes[what]
        else
            setText(MsgArea, "Unknown discount selected"
        end if
    else
        setText(MsgArea, "No discount selected")
    end if
end procedure
