How pages inherit content within sites
Different themes have different active inheritance drop zones. Most support the right column and footer inheritance with only the magazine themes currently inheriting Header content for the magazine's name and home link. Please refer to specific theme documentation on active inheritance drop zones or file a JIRA ticket if things aren't working as planned.
The best way to visualize inheritance is the Column view in My Sites. Components inherit from left to right in the columns, starting with the 'en' page that inherits to all pages in a site.
Global inheritance within a site to all child pages happens from the 'en' page. Any content on the 'en' page in an inheritance drop zone will inherit to all pages of a site.
Local inheritance happens from parent page to child page(s) and all descendants.
The following example illustrates how to control inheritance from parent to descendant pages, from global or local parents.
If you click on any visible Inherited Paragraph System box in a page and then the Config (wrench) icon, you will see settings for that drop zone, on that page.
Cancel inheritance will stop propogation of any content on the current page or from a parent page, to the current page and its child pages.
Disable inheritance will stop propogation of any content from a parent page to the current page and its child pages.
In the diagram, Cancel inheritance is turned on for Page A which is the parent of Page B and any other descendant pages. This means Page A and all of its descendants do not inherit any content from the 'en' page or any other parents of Page A. Page A and its descendats can have specific items to their respective page appear in the inheritance drop zones. With Cancel inheritance turned on, nothing is inherited to Page B, its siblings or children, from Page A or any parent.
In the diagram, Disable inheritance is turned on for Page A which is the parent of Page B and any other descendant pages. This means Page A and all of its descendants do not inherit any content from the 'en' page, but any content from Page A, in an inheritance drop zone, is inherited to its descendants. With Disable inheritance turned on, Page A and its descendats share content from Page A, but not from the 'en' page or any other parents of Page A.
