Defines grouping levels to be applied to the data. This object can have the following fields:

  • selector: String
    The field name to group by.
  • desc: Boolean
    Defines the selector field's descending sort order.
  • isExpanded: Boolean
    Defines whether the group's data objects should be returned instead of grouping data. Relevant only for the last group.
