In the repeatable block we have dropdown which contains three values , while doing add item, already selected item in the dropdown should be disabled or hidden. So that we can narrow down the option to user.
Kindly help to assist on this. Thanks.

You would need to use a data-driven dropdown, with a calculation rule that returns only the unselected options.
