Much like the author of this article, our company needs a way to automatically generate a table of contents for large articles. After finding out we can use jQuery, I put together a script that will automagically create a tiered table of contents based on the Header tags used in the article.
Click on the JS tab, then paste in the code at the end:
That should do it.. as long as you've used proper heading tags (H1, H2, etc), a Table of Contents will be created any time you load the article.
