Collapse

The two headers on this page have collapsible content. The first one sets the content to be hidden when the page is first loaded, while the second has the content initially displayed.

 == Header #1 ==
 <div class="mw-collapsible mw-collapsed">
 This is more text stored in a collapsible section which is initially collapsed.
 </div>
 
 == Header #2 ==
 <div class="mw-collapsible"> 
 This section is uncollapsed by default.
 </div>

The content for each header is placed within a <div> element with a class attribute set to "mw-collapsible". If you want to start with the text hidden, add "mw-collapsed" to the class as shown for Header #2.

Removing table of contents

When using collapsible header system, it might be useful to remove the automatic table of contents. This is done by adding this text to the top of the page:

  __NOTOC__

That is "NOTOC" ("no table of contents") surrounded by two underscore characters on each side.
