Abstract
A portable communication apparatus provides a display on which the user is able to easily find out the object item at the time of displaying a list of the plural items. In the case where the functional items are separated into some groups and formed into hierarchical structure, the display layout is changed for each hierarchy at the time of displaying the list of the items. Therefore, by viewing the differences among the display layouts, the user can know which hierarchy is currently being displayed and can easily find out the object item.
