The TOC filter 8.x-2.x requires the TOC API module which provides a framework for creating table of contents (TOC) from an HTML document's header tags.
Besides the flexibility, provided by the TOC API, for defining how a table of contents is displayed, the TOC filter module includes the ability to
- Move table of contents to a block
- Customize an individual table of contents
IMPORTANT: Make sure your text formats are configured to support selected header tags.
Copy/upload the tocfilter.module and tocapi.module to the modules directory of your Drupal installation.
Enable the 'TOC filter' module in 'Extend'. (/admin/modules)
Visit the 'Configuration > Content authoring > Text formats and editors' (/admin/config/content/formats). Click "configure" next to the input format you want to enable the 'Table of Contents' filter on.
Enable (check) the 'Table of Contents' filter under the list of filters and save the configuration.
(optional) Visit the 'Configuration > Site Structure > Table of contents' (/admin/structure/toc).
(optional) Place the TOC filter block on all pages. (/admin/structure/block)
