Offering users a View menu is not required. Without it, they will be locked into a specific view depending on the factors listed above.
Note: The option to display, or return to the Main Profile from a profile view on cases must be set and configured directly on each profile view. A Views menu configured in a Menu Box (see below) does not display the "Main Profile" link. Edit the profile view and add the "Profile Views" element to one of the Side/Action Elements sections. Typically the Views section to be consistent. The default "Yes" to show all available profiles will include a link to "Main Profile".
Administrators considering setting up views for cases may also want to consider controlling the Side/Action Elements of the main profile and profile views using Menu Boxes.
The Side/Action Elements of a profile are specific to that profile, and must be built for each profile. If a site has multiple case profile views, this can make changes to all views tedious. An alternative is to add a single Menu Box element to a profile that will contain all the links defined in that Menu Box.
For example, if a site has 3 profile views, then changing permissions on a common link will require 4 edits — the main profile and each of the 3 profile views. If that link was defined in a menu box, a single edit of the menu box would take care of all 4 profiles.
