2.2.2.3-2 Hierarchic Menus for Sequential Selection

When menu selection must be made from a long list, and not all options can be displayed at once, a hierarchic sequence of menu selections should be provided rather than one long multipage menu.

Additional Information:
Where a long list is already structured for other purposes, such as a list of customers, a parts inventory, or a file directory, it might be reasonable for the user to be required to scan multiple display pages to find a particular item. Even in such cases, however, an imposed structure for sequential access may prove more efficient, as when a user can make preliminary letter choices to access a long alphabetic list. Beginning users may learn faster and understand better a menu permitting a single choice from all available options, when those can be displayed on one page. However, a single long menu that extends for more than one page will hinder learning and use.
