A pull down list box is very similar to a full list box, except that this control is displayed on a single line
and provides a pull down arrow. By clicking on that arrow the list box expands to display several lines
of information on the screen. After making a selection, the list box collapses back down to one line.
For Example:
By clicking (left button) on the down arrow, the board group list box will expand to show more of the
possible choices. The operator can select any line within the list box by simply clicking (left mouse) on
that line. The edit box will return to its original state with the new selection being displayed.
