title: Provide step by step multi-option instructions in MediaWiki pages
body: <p>We have a wiki page in MediaWiki with instructions like this:</p>
  
  <ul>
  <li>complete instruction 1</li>
  <li>also in case A do this</li>
  <li>complete instruction 2</li>
  <li>also in case B do this</li>
  <li>complete instruction 3</li>
  <li>etc</li>
  </ul>
  
  <p>Is there a way to show just the lines / paragraphs in which we are interested? E.g. someone could show <strong>all</strong> rows or hide certain rows, preferably at the touch of a button.</p>
  
  <p>I assume it is some combination of tables, <a href="http://www.mediawiki.org/wiki/Extension%3aToggleDisplay" rel="nofollow">ToggleDisplay</a> and templates but I don't know more than that. Any else know?</p>
