Step-by-step guide: How to change the initial expand or collapse status of the HTML table of contents

By default, HelpNDoc automatically expands the table of contents when publishing documentation in HTML, displaying all topics. It is simple to modify this setting to automatically collapse topics, displaying only parent-level topics in the table of contents. Readers can then click a parent topic, expanding it to view the children topics.
