Edit list (array)  datatype default values  from 
    the List Values editor, which  provides a table view that includes all members of the list.
            The List  Values editor allows you to edit array datatypes  from various places, including personalization key default values. You can:
            
         
- Editing an array datatype depends on the context from which you access the editor. For example:   
 
                    - Personalization keys – if creating a new personalization key that includes an array  datatype as the Type, select the ellipses (...) next to the Default values field. For existing personalization keys, right-click the personalization key and select Properties, and select the ellipses (...) next to the Default values field. 
 
- Attributes – from the Properties view, select the Attributes Mapping tab.  If the attribute is an  array, select the corresponding ellipses (...) in the Default value field.
 
- Others – similar to attributes, if datatype supports arrays, and allows you to set default values, select the ellipses (...) in the Default value field.
 
                  
- Make changes from the editor as needed.
 The editor provides a Value column where you can define a value for array members, and use the Add, Delete, and Delete all buttons to create or delete array members as needed.
   
                The type of array determines what values you can select. For example, if you add a Datetime type, select a default value from the  calendar.
 
- Click Ok when finished.
