Selected outline properties
To make the outline available to public access users
This option must be enabled for the outline to be available to public access users - users with no access to the database, but who have the privilege to read/write public documents. (Public access users will be able to open the database to views enabled for public access and to read/write documents enabled for public access.) If the designer wants the public access user to be able to use the outline for navigation, the outline must be enabled for public access users. The page and frameset in which the outline appears must also be enabled for public access users.
To make the outline read only
If you select "Read only," users cannot edit the outline in place.
