Groups items together in an aggregation.

The group() method refines a WixDataAggregate so that its items are grouped by the specified field or fields.

You can perform aggregations on the groups using the following methods:

  • avg()
  • count()
  • max()
  • min()
  • sum()

To filter grouped results, use the having() method.

Notes:

  • Aggregations can only be used on collections you have created. They cannot be used on Wix app collections.
  • You can only call the group() method once per aggregate query.
