A basic tooltips extension available to download from SourceForge.
Download and extract the file(s) in a directory called ToolTip in your extensions/ folder.
Add the following code at the bottom of your LocalSettings.php:
require_once( "$IP/extensions/ToolTip/ToolTip.php" );Open the "Vector.php" file and find the following (around line 73);
$out->addModuleStyles( $styles );
And directly below paste;
$out->addModuleStyles( 'ext.ToolTip' );
Return to MediaWiki refresh the browser (Shift + Ctrl + R for Chrome and Firefox).
If there's a problem navigate to "Special:Version" on your Wiki to verify that the extension is successfully installed. Problems are normally due to mistakes editing Vector!
