filter( )

Filters out items from being used in an aggregation.

The filter() function refines a WixDataAggregate so that it only includes items from the aggregate's collection which match the specified filter criteria.

To create a filter, use the wix-data filter() function.

Filtering using filter() takes place before grouping is performed on the aggregation. To filter grouped results, use the having() function.

Note: Aggregations can only be used on collections you have created. They cannot be used on Wix App Collections.
