The content editor allows you to edit the contents of a landing page cell. It is described it its own section within the RPI documentation.
You can add attributes (except band-based model project and exists in table attributes) to landing page content. When values for attributes with matching names are present in the realtime cache, content added to a landing page in this way can be personalized. The same applies when including text and HTML assets containing embedded attributes in landing pages.
When an attribute has been embedded in a landing page, if a value for the attribute is available for the current visitor in the realtime cache, the value will be shown in the landing page. If a value is not available, if a default value is provided, it is displayed. If a default value was not provided, no data is displayed. If multiple values for the attribute are available in the cache, the first value persisted in the cache is shown.
Note that If a landing page’s content contains the HTML ‘<body>’, the landing page is deemed to be invalid.
