Hierarchical Drop-Down List Boxes

      Disclosed is a new type of drop-down list box which provides

contents are provided.  Whereas conventional drop down list boxes
present a simple list of choices, the disclosed invention provides
for the hierarchical organization of list box contents.

      As shown in Section (a) of the Figure, provision of
hierarchical lists allows the organization of lengthy list contents
into a structured format.  This results in a new type of control
known as a Hierarchical Drop-Down List Box (HDDLB).

      An HDDLB behaves in essentially the same way as a regular DDLB.
However, individual choice items may include the cascade graphic
which provides access to additional groups of choices.  Selection of
a cascade choice item automatically surfaces the next level of
choices, displayed in a regular list box.  Likewise, this list box
may also contain further cascade choices, the selection of which
surfaces lower level groups.

      Once the user has made their required selection, the
hierarchical lists become hidden, and the user selection reflected in
the usual way, as a single line.  The format for displaying the
selection may vary depending upon whether or not it is important to
display the hierarchical information while the HDDLB in unselected.
If it is important, then it is suggested that '/' characters be used
to separate the individual hierarchical choices (b...
