Which file controls the display of menu pages in SailPoint?

The file that controls the display of menu pages in SailPoint is appPage.xhtml. This is because appPage.xhtml is specifically designed to define the layout and functionality of application pages within the IdentityIQ interface. It is part of the foundational structure that dictates how various components are presented to users, including navigation menus and links to other application features.

While other files, such as ngAppPage.xhtml and ui/css/ui-custom.css, may contribute to the overall user interface and styling, they do not specifically handle the display of the main application menus. The ngAppPage.xhtml file is typically used for Angular-based applications within IIQ, and ui-custom.css would primarily handle CSS styling rather than defining the menu page structures. Therefore, the correct answer accurately reflects the specific file responsible for managing the layout and presentation of menu pages within the SailPoint IdentityIQ system.
