Documents created with eaDocX are fully functional MS Word documents; therefore, the creation of the Table of Contents (TOC) is done by selecting the Automatic Table of Contents from the Word document menu.
Word then adds the table of contents and auto-populates headings from those defined in all your document sections – both EA generated and handwritten.
If you add or delete EA sections, then the TOC will update to reflect the full document content each time you regenerate your whole document (Normal, Interactive or Draft regeneration).
See Setting Section Heading Levels for more information about structuring your document.
