Select multiple cards in Cards layout at once

[airidasbrikas23]

There are three view types for matrix field: element index, in-line and As Cards.

Currently only As Cards do not support selecting multiple entries (cards) at the same time.

Why useful?

• Copying, duplicating or deleting multiple entries is very laborious now and there is no way for the user to get it done faster without changing configuration.
