The CategoryDropdown extension creates a dropdown within the content of a page with options that when selected navigate to those pages. It was triggered on the question posted on stack overflow requesting a category dropdown extension.
Usage
[edit]A couple of example usages, the 'all' doesn't really matter, there just has to be some value present.
<categorydropdown type="category" parent="all" />
<categorydropdown type="category" />
<categorydropdown type="page" parent="all" />
<categorydropdown type="page" />
Installation
[edit]- Copy the code into files and place the file(s) in a directory called
CategoryDropdown
in yourextensions/
folder. - Add the following code at the bottom of your LocalSettings.php file:
wfLoadExtension( 'CategoryDropdown' );
Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.
Code
[edit]- CategoryDropdown_body.php
