The Object Cascade
The Object Cascade is the method by which pages or other content items inherit the objects of their parent. The wonderful part about the object cascade is that it allows for ease of use when editing or creating pages. You can select any number of display objects to include on a page without having to repeat the process for every page in that section.
For example, the products section of your site has its own unique navigation and a product showcase in the left sidebar. Instead of inserting the objects on each page, you can simply let the rest of the pages in the section "inherit" the object from the first page of the section.
Later on, you decide that the Product showcase should only display on the homepage and not throughout the Products section. Since you used the object cascade to display the showcase on the entire Products section, you can remove the object from all pages by removing it from the Products section parent.
Inheritance Rules
There are three cascade inheritance rules a page can have:
- Inherit Cascade: This means the page will inherit the cascade that its parent inherits or begins. This is the default for any new page.
- Start New Cascade: This option starts a new cascade, starting with the specific page. Objects will not be inherited from the parent, but objects will be cascaded to children.
- Do Not Inherit Cascade: This option allows for a single page to ignore any objects from the previous cascade without affecting the pages below it.
The Content Objects Tab
The content objects tab which appears on the Edit Content page, is where you can manage inheritance rules and objects for each page. This tab is covered in depth in the Working with Content section under the Content Objects Tab.
