Accessibility enhancements for indexes

Last updated on Jun 2, 2026

List of accessibility enhancements available for indexes while exporting an Adobe InDesign document to EPUB (Reflowable) format.

You can observe the following accessibility enhancements in the Indexes feature after exporting InDesign documents to EPUB (Reflowable) format:

  • Indexes are exported in a <nav> and not in a <section> or <div>.
  • Indexes have the ARIA role applied as <nav role=”doc-index”>.
  • Indexes have a top-level header and subheaders for the various alphabetical parts.
  • Indexes have the bulk of the content in unordered lists with no list markers.
  • Indexes can now have ARIA labels when referring to a range of pages.
  • Indexes with regular text can use export tagging combined with ARIA role to create <nav role=”doc-index”>. When the index feature is used, this markup is generated automatically.
