Mediawiki Extension ShowMe
Template-uk:Class-Infobox-Software
Description
The ShowMe extension allows inserting a dropdown into pages, that will show different elements on the page depending on which option is selected.
Installation
Download
Download and place the file(s) in a directory called ShowMe in your extensions/ folder.
Activation
Add the following code at the bottom of your LocalSettings.php:
wfLoadExtension( 'ShowMe' );
Usage
Use the <showme> tag. It has an optional name parameter, which can set the name and id of the <select> element. Each line between the tags should contain an option. It must consist of the text to be shown, followed by a pipe, followed by the class name of an element (or elements) on the page which should be shown when this option is selected.
While one option is selected, the elements corresponding to all other options become hidden. To avoid flashing of elements that are supposed to be hidden, you can optionally add style="display: none;" to every option other than the first.
Example
