7.3.3 Grouping contents entries
Suppose you want to group the chapters in your document so that each group appears in the contents with its own “book” icon, in effect creating an additional contents level above the chapter level, and thus providing a more compact table of contents when only the first level is displayed in a Help viewer.
In your FrameMaker book (or a clone of the book intended for Help output), add a new chapter before the first chapter of each group. Give the titles of these new chapters a new format; for example, PartTitle. You can include summary text under the title, or leave the title as the only content.
In your project configuration file, edit the entries under [HelpContentsLevels] so that PartTitle is at a higher level than the chapter titles. If not all chapters are to be included in such a group, change the title format of the chapters that are in groups; for example, from ChapterTitle to SubChapterTitle; and give SubChapterTitle a setting that places it just below PartTitle. So you might have:
You may need to adjust subhead levels also, if you have chapters at different contents levels.
