This script is for PERSONAL use only!

You are free to install this script for yourself, but it is not allowed to be used wiki-wide (e.g., in MediaWiki:Common.js or MediaWiki:Wikia.js), as it would violate FANDOM's Terms of Use. (See the customization policy)

High priority

This script is currently in Alpha testing. It is functional but there are known problems and some of the features are incomplete. It should be safe to use but anything and everything about how it works and looks may change drastically at any time.

This script will add a button to the Oasis toolbar that can hide the Wikia Rail when clicked (the bar on the right with the Recent Activity / Recent Uploads / Ads / etc) and restore it when clicked again. The search box will remain visible after the rail is hidden so you won't lose any important functionality by hiding it.

By default, Oasis squeezes articles into a rather narrow 670px column, you can use this tool to get the full 1010px width instead. This reduces the amount of scrolling needed to read a whole article.

Beyond article pages, the script also provides functionality for improving Edit pages by hiding the Editor Rail in Visual mode, not just Source mode. It also includes OasisWideMode built-in, which let's you enable the 1200px Oasis skin on any wiki.


To install this script, you can import it to your wikia.js on a single Wiki to affect only that one Wiki, or your global.js on Community Central to have it affect every Wiki across Wikia.

importScriptPage('HideRail/code.js', 'dev');

The script does not work on Monobook for obvious reasons, it has no effect on that skin so it is safe if you switch back and forth.

Appearance Customisation

You can customise the appearance of the button using your Wikia.css or global.css:

/* Disable the default arrow images */
a.hiderail-link-expand, a.hiderail-link-shrink {
    padding-left: 0;
    padding-right: 0;
    background-image: none;
/*** Example 1 ***/
/* Display text arrows instead */
.hiderail-link-expand:after {
    content: "  \2192";
.hiderail-link-shrink:before {
    content: "\2190  ";
/*** Example 2 ***/
/* Display custom icons on the left side always */
.hiderail-link-expand:before {
    content: url("http://whatever/my custom icon 1.png") ' ';
.hiderail-link-shrink:before {
    content: url("http://whatever/my custom icon 2.png") ' ';

The CSS classes are hiderail-link-shrink for the shrink button, hiderail-link-expand for the expand button and hiderail-link-generic for when the expand button is disabled (no rail).
