You can create rules in the root folder of Experience Manager, or within a content folder.
Rules determine the content that displays in a page or page section as well as any conditions that must be met before the content displays. Your application can reference the rule directly or dynamically by referencing the content folder that contains the item.
To create a rule:
Check the toolbar and verify that you are working in the correct project.
In the Rules section of the navigation tree, right-click the folder and select Add Rule.
The rule that you created only appears in the project. This allows you to edit and test your content until you have determined it is ready to publish to the site.
You still need to choose a template, determine when and where the content displays, and designate content.
