Repeated items in the list

[nerio]

In the form I have repeated groups. But in the list I would not like to see a row for each element of the group but only a row for "id". How can I do?

Have you tried setting "Display mode" to "Merge rows"?
List -> Data -> Joins tab

Thank you. Fixed, also disabling Include in list query / view
in repeated groups.
