Select additional columns from the target list. These column will be displayed to the end-user above the Cascading LookApp field as filters, so end-users will be able to filter items in the Cascading LookApp column in run-time. Example: The "Account" Cascading LookApp column is configured to show the "Act. Mgr" column from te target list as a filter:
Filter by another column in this list
(Cascaded master-detail relation)
This option enables you to implement Cascading fields, where one field filters the other, such as Account drop-down that filters a Account Contacts drop-down.
To set-up filtering by another column:
Allow multiple values
Check this property to show a multiple value lookup field.

Add new item content type
Select a content type to be used when creating a new item in the target list (when clicking the “Add new item” link below the Cascading LookApp field)
