I am generating WebHelp on Windows 7 Professional and viewing the generated help in IE 9.
In the TOC pod it looks like the TOC has only two levels of hierarchy for topics: Books and pages. There does not appear to be a way to add a topic below a page in the TOC hierarchy (a sub page of a page, in other words).
In the attached sceen shot, a topic is highlighted, and the right pointing arrow is not available.
Surely RH 10 does not restrict the TOC to just two levels.
Please let me know how to move a topic to appear under a page in the TOC.
