How to Configure Delete Confirmation Dialog

Aim of this article	For delete and mass delete actions, it is possible to enable a safer 'Confirm delete' dialog with an extra check-box where users confirm the deletion of a given number of items. This way users confirm twice that they really want to delete the items and thus the risk of an error is reduced.

Steps:

Go to Configuration > All Modules > Advanced Configuration Options.
Set the advancedDeleteConfirmationDialogThreshold option to a value which represents the threshold, i.e. minimum number of items which should trigger this more secure delete confirmation.
- If the option is set to 1 or more, this more secure delete confirmation is displayed.
- If not set or set to 0 or does not exist, the simple delete confirmation (without the check-box) is displayed.
Save the changes.
