In OpenCms 8.5.0 a new Inheritance Group is introduced to be used within a containerpage model.

The inheritance group is a content element to reference a group of another content elements. It extends the functionality of the element group by passing on the content element configuration down the navigation line. In each navigation level the user can define per drag & drop the elements, which should be referenced by the inheritance group in the similar way the element group is edited. The content of the group is inherited automatically to the below navigation levels. Additionally the elements referenced by the inheritance group can be added, removed or rearranged in every navigation level. The new configuration will be inherited only to the below levels.

Use an inheritance group instead of the element group in the containerpage model, if you would like to achieve following effects on the website:

• A common content part, which is repeated on all pages inside a navigation tree line.
• All changes like editing, dropping new elements or deleting elements from the inheritance group are inherited to all pages below the current navigation level.
• It should be possible to change elements at specific navigation level. These changes will be populated only to the pages in navigation below this point.

• Create and configure a page model. Please check the Model Containerpage Demo I to learn more about page models.
• Add the required inheritance groups to the page model. Edit the title and the description of the created inheritance groups, but do not add any elements to the group at this step.
• Use the configured page model to create the navigation structure of the website.
• Now you can individually change elements in the specific navigation level. This changes will be inherited to the level below.
