An option in the left menu (such as IPDU in Figure 6.1) often has several related screens associated with it. The related screens are accessed as tabs.
Dialogs are screens that appear when an administrative user clicks an Add or Edit button. While dialogs are active, the buttons at the bottom of the screen, which are listed in Table 3-1, and the menu options are grayed out. The appearance of an active dialog is shown the following screen example. The grayed out options and buttons become active only after the administrative user clicks either the OK or Cancel button. The administrative user may need to click other types of buttons to exit other types of dialogs.
