Editing Fields in Datasheet View
Current limitation: values of Virto Cross-Site Lookup Selector columns are entered and shown in the classic list forms. In the modern list view and in Quick edit, these columns show “[object Object]” instead of the value.
The steps below show editing Virto Cross-Site Lookup fields in Datasheet View of an earlier SharePoint version. Switch to Datasheet View.

Make changes to required fields right on the page without moving to edit item window.

After editing dependencies will not work as before.
