cascading parameters
In BIRT technology, report parameters that have a hierarchical relationship, for example:
Territory
  Country
    State
      City
In a group of cascading parameters, each report parameter displays a set of values. When a report user selects a value from the top-level parameter, the selected value determines the values that the next parameter displays, and so on. Cascading parameters display only relevant values to the user. Figure G-4 shows cascading parameters as they appear to a report user.
