A collection of menu choices related to a selected menu choice, which provides a hierarchical organization to a pull-down menu.

Cascade menus:

• Group related menu choices together in a sub-menu to reduce the number of choices displayed in a pull-down menu.

• Display an arrow pointing in the direction the cascade appears (in the selected (parent) menu choice).

• Show the cascaded menu if the user selects the parent choice and moves the mouse pointer in the direction of the arrow.

• Use no more than two levels of cascades from a menu.
