What is an App Shell?
Answer: In ServiceNow, an app shell is a wrapper for an experience page that defines the type of experience being built.
It provides the general look and feel for an application, including the header, footer, navigation menu, and content area.
There are two default app shells in the Quebec Release: Workspace and Portal.
Each app shell has different components and is used for different types of experiences:
Workspace
This app shell is used for multi-tasking, such as working on multiple records at once.
It includes a user menu and tab navigation.
Portal
This app shell is used for focused workflows and wizard flows that don't require multi-tasking.
It includes a user menu, breadcrumbs, and an experience header.
