A module is a navigation item that provides access to a feature or functionality in ServiceNow.
Modules must have a link type, which determines how the module behaves when clicked. The
following is a list of link types:
Assessment. This is a link type that opens an assessment, which is a survey or questionnaire that
measures the effectiveness of a process or service.
List of Records. This is a link type that opens a list of records from a table or a saved filter.
Separator. This is a link type that creates a horizontal line to separate modules in the application
menu.
Timeline Page. This is a link type that opens a timeline page, which is a graphical representation of
the duration and sequence of events or tasks.
The following are not link types, but other module attributes or field types:
List of Records, Separator, Catalog Type, Roles. These are not link types, but a combination of a link
type (List of Records), a module attribute (Separator), a field type (Catalog Type), and a user attribute
