Documentation for dynamic navigation boxes.

Dynamic navigation boxes use a combination of CSS and Javascript to make collapsible navigation boxes. The technical parts comprise style sheet declarations in MediaWiki:Common.css, and Javascript code in MediaWiki:Common.js.

How to use

NavFrame divs

The basic concept here is to use the div element within a Wiki article's markup code to identify certain content (which we'll call the "details" here) that we want the user to be able to "show" or "hide". The markup code used to achieve this effect comprises three main classes: NavFrame, NavHead, NavContent. The default behavior of this code will initially "show" the details, as well as a link to "hide" the details. To reverse the default behavior, so that the details are initially hidden, the NavContent element can be declared with style="display:none;".

Simple example

You will need to create three div elements:

<div class="NavFrame">
  <div class="NavHead">[... This is the title of your collapsible content ...]</div>
  <div class="NavContent">
    [... The content you want to hide goes here ...]
  </div>
</div>

[... This is the title of your collapsible content ...]

[... The content you want to hide goes here ...]

To initially hide the content do this:

<div class="NavFrame">
  <div class="NavHead">[... This is the title of the hidden content ...]</div>
  <div class="NavContent" style="display:none;">
    [... This content is initially hidden ...]
  </div>
</div>

[... This is the title of the hidden content ...]

[... This content is initially hidden ...]

Mixed classes example

You can even apply other classes along with these, making a more styled design rather than if you were to use the standard classes:

<div class="messagebox standard-talk NavFrame">
  <div class="somerandomclass NavHead">
    [... This is the title; it does not have to be plain text, you can get creative here ...]</div>
  <div class="NavContent anotherclass">
    [... The content you want to hide goes here ...]
  </div>
</div>

[... This is the title; it does not have to be plain text, you can get creative here ...]

[... The content you want to hide goes here ...]

Collapsible tables

More information: en:Wikipedia:Collapsible tables

The initial state of any collapsible content can be controlled using a "collapsible table", because it also allows a table with only one element with content, and a header.

Limitations

Currently, the three Nav* classes apply styles of their own. When mixing classes, this causes some of the Nav styles to override other styles (in the above example, NavFrame is overriding the styles from .messagebox.standard-talk).

This limitation does not affect collapsible tables.

Accessibility

All browsers from Internet Explorer 5.5 and on (IE5.5/6/7, Firefox, Safari / KHTML, Opera 8/9, etc.) that support JavaScript will properly collapse the elements.

Internet Explorer 5 and browsers which do not support JavaScript will render the elements without the [hide/show] links and will not collapse them.
