Global Sidebar Include
These steps can be followed to add an include in any subfolder. Simply use the folder "Access" settings instead of "Site Access".
- Create a folder called "_includes" in the root of the site
 - Inside "_includes", create a new blank file with the extension "pcf"
 - Copy and paste the following code into the source of the new file:
<?xml version="1.0" encoding="UTF-8"?>
<?pcf-stylesheet site="www" path="/_resources/xsl/left-include.xsl" extension="inc"?><!DOCTYPE document SYSTEM "http://commons.omniupdate.com/dtd/standard.dtd">
<document xmlns:ouc="http://omniupdate.com/XSL/Variables">
<ouc:div label="leftcolumninclude" group="Everyone" button-text="Include Content" break="break"><ouc:editor csspath="/_resources/ou/editor/maincontent.css" cssmenu="/_resources/ou/editor/styles.txt" width="955" wysiwyg-class="maincontent"/><p> </p>
</ouc:div></document>
