Cascading Lookapp Configuration

After you install the Cascading LookApp add-in and add it to your site, you will see its ribbon button in every list’s “List” ribbon:

Clicking this ribbon button will open the list’s Cascading LookApp settings page:

This page enables you to create new Cascading Lookup columns or convert an existing Lookup column to Cascading Lookup column.


Settings page properties

The Cascading LookApp's settings page includes the following properties:
