f13dev

Generate a table of contents based on header tags within the post. Outputs an indented list of anchor links at the top of each page or post linking to the relevant header tag.
Tabe of Contents does not require any configuration. On page or post loading, the content is examined for header tags that can be used to generate a ToC. If the header tag does not have an ID attribute one will be added for the purposes of linking, otherwise the existing ID tag will be used.

This plugin makes it easy to create a wiki like TOC (table of contents) in your posts or pages using shortcode, no linking or creating anchor is needed.
Unlike other plugins this is 100% semantic, ie drop the comment string: <code></code>.
Into your content body and the plugin will do the rest ie it will generate a table of contents based on the h2 and h3 tags in the content body.
If the comment is not included the table of contents is not generated.
