Understanding the Table of Contents and Merge Settings
Not only can the table of contents be generated from defining your heading paragraph styles, the table of contents can also be generated using Merge Settings. Merge Settings allow you to combine multiple top-level groups into a single hierarchy. Not all output formats support merging. For more information see “Merging Help Systems (Multivolume Help)”.
Note: Since your Stationery design project is used to create Stationery, and Merge Settings are not stored in Stationery, you do not need to configure Merge Settings for your Stationery design project. You can configure the Merge Settings in your ePublisher Express projects, since these settings vary based on individual project needs.
