A Table of Contents provides a hierarchy of the folders, topics, and any subfolders that you have in the output of your project. This gives the reader an ability to view the Help system as a whole and its individual topics. With a Table of Contents, the reader can quickly select and view a topic of their choice.
You can have multiple Tables of Contents in a single project, depending on the type of output that you want for your readers. For example, you can have a Table of Contents to cater to a specific audience (say, Developers) and another Table of Contents for a different audience (say, End users). You can simultaneously maintain the two Table of Contents files in the Table of Contents panel of a project. At the time of publishing your project, you can then decide which Table of Contents file you want in your output.
The Table of Contents field displays all your created Table of Contents files in the project. Use the drop-down list to select your desired Table of Contents file.
The selected Table of Contents is then included in your output. See Generate output for details on how to generate the output.
