Forum:SH Archive/Content Boxes?

Sorry to be annoying people with questions, but I've been looking all over and I just can't figure out, How do those Content boxes show up? You know, the light blue boxes at the beginning of an article that link to each subtitle of the page? Do they just automatically pop up when there's like 4 headings or is there a code for them or what? Carth=love 17:53, 18 February 2008 (UTC)
