Lateral Fallback

A field falls back to the value of another field, or chain of fields

Configuration

1. If a template has a field that requires lateral fallback then that template must be based on the /sitecore/templates/System/Templates/Fallback template template not /sitecore/templates/System/Templates/Standard template
2. Go to the __standard values of the template or the item itself and make sure View -> Standard Fields is checked.
3. You should see a "Fallback" section that has a Single-Line Text field type called Fallback Fields.
4. This field may be formatted in 2 different ways, Name/Value pair or XML.
   Name/Value pair - Should be formatted like a query string with pipes separating multiple values. eg. Name=Value1|Value2&Name2=Value3
   XML -
   <fallback> <setting target="{id}" source="{id}|{id}|{id}..." enableEllipsis="true|false" clipAt="{number chars}" /> <setting target="{id}" source="{id}|{id}|{id}..." enableEllipsis="true|false" clipAt="{number chars}" /> </fallback>
