Delete RecordSetItem

On the left side of each RecordSetItem, i.e., each database RecordSetItem,
there is a “Delete” button, which would remove only that specific item.

If you want to delete more than one database RecordSetItem,
select a checkbox field on the left of the individual RecordSetItem that you want to remove.
Click on the “Delete marked items (#)” button in the bottom left corner.
This button will also show the number of selected items in parentheses.

In the pop-up window, select “Yes” to permanently delete item, that is, all marked items from the database.
