How to update your table of contents in Zendesk
Whenever you create new articles or edit existing ones your changes will be pushed to Zendesk if the article is visible (unless you save a draft).
But if you make modifications to the structure of your table of contents you will need to manually push these changes to Zendesk. This applies anytime you move articles between chapters or reorder articles in chapters.
How to push changes to your table of contents
From the Site Contents menu, select Push changes to Zendesk HC.
A dialog will appear asking which parts of the table of contents you would like to update. You can choose to just update the manual titles and positions in Zendesk or you can choose to update the title and positions of manuals, chapters, and articles.
