On-Page Linking for Rich-Text

I am trying to create a table of contents at the top of my page that will be able to link down to a heading within my rich text element for simpler navigation of long blog posts. Any idea on how I can go about this?

Here is my site Read-Only: LINK
(how to share your site Read-Only link)


I need to do this also, Anyone??

Any update on this? I am trying to do the same on my project.
