Besides creating a table of contents for an entire wiki, you can create a table of contents that pulls only from the headers located on one page (called an in-page table of contents). This capability is added through an add-on called the In-page TOC - available in the Telligent Marketplace.
The in-page TOC widget displays contents of headers down to < H4 >.
To utilize the in-page TOC, type [ toc ] on a line by itself inside the document.
