The TocTree extension allows for initial expansion and collapsing of the table of contents.

Installation

• Download and move the extracted TocTree folder to your extensions/ directory.
  Developers and code contributors should install the extension from Git instead, using:

  cd extensions/
  git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/TocTree
  

• Add the following code at the bottom of your LocalSettings.php file:

  wfLoadExtension( 'TocTree' );
  

• Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

Customization

The PHP script will add two new options to the user preferences. They were added to the Misc section:

• Floated table of contents
• Expand table of contents

Defaults are collapsed but not floated tocs. You can overwrite the default values by setting true in your LocalSettings.php file:

$wgDefaultUserOptions['toc-floated'] = false;
$wgDefaultUserOptions['toc-expand'] = false;

Prevention of TOC floating

The author has the opportunity to prevent floating of the TOC set by the user(s) by using a div tag with the style class noFloat enclosing the TOC.

<div class="noFloat">__TOC__</div>

Known problems

There are the well-known problems of floated boxes like:

• Missing list bullets
• Design problems of narrow TOCs and positioning problems with text and wide right-floated boxes.

Additional:

• Bidi support (right-to-left writing direction) implemented but not yet tested (for instance needed for Hebrew and Arabic).
• Support of only the MonoBook and Vector skins.
