This is a mix-and-match template allowing you to create a horizontal, page-width timeline. It's simplest to access it by typing {{include timeline}} into an article, clicking preview, and following the links that appear.

Rows are provided by a series of templates, and it's easy to adapt your own. You can use:

{{Horizontal timeline
|title=
|title-colour=
|collapsible=
|link-to= (Use {{subst:PAGENAMEE}} [sic] on a subpage; leave blank if embedded in an article)
|caption=
|margin=
|Row1=
|Row2=
|…
}}

See the What links here list for pages using this template. Here's one crude example: साँचा:Include timeline
