Plugin Name: Extended Table of Contents (with nextpage support)
|
||||
Plugin URI: http://http://www.web-cloud-apps.com/produkte/wordpress-extended-toc/
|
||||
Description: This plugin automatically generates and inserts a table of contents (ToC) to your pages and posts, based on tags h1-h6. Whenever the plugin discovers more than a certain amount of headings (default: 3) the ToC is inserted at the top of the page. This plugin also can handle posts that are divided into pages by the nextpage-wordpress-tag. Any feedback or suggestions are welcome.
