The Enhanced Lookup Column provides cross-site list support, default values, turn on/off editing, filtering choices by view and groups. While still maintaining the same capabilities as the standard Lookup Column, this column provides a rich set of features to further the parent-child relationship between list items in SharePoint.
Features
- Cross-site lookup
- Default values via the url (querystring)
- Specify whether the value can be edited
- Single and multi select supported
- Group By filtering to narrow down the choices
