Re: Wiki table of contents on first page (like tikiwiki documentation)?
more information for the answer from Clausen:
http://doc.tikiwiki.org/toc
http://doc.tikiwiki.org/Structures
Moreover, you might want to add this type of table of contents, but just for the contents of a single page (from all tis headings of different levels, etc.)
Then, read this:
http://doc.tikiwiki.org/maketoc
HTH
P.S: And by the way, Horch, welcome to TikiWiki Community!
