Drop-down filter: multiple selection and benchmark

Multiple selection:

the selected values are summed up.

Example:

[{"name": "Land", "filter": 431, "multiple": true}, {"reset": "Reset all filters"}]  

Result: A total value across all countries is formed.

Benchmark-Drop-Down:

each selected value is shown individually.

Example:

[{"name": "Land", "filter": 431, "type": "benchmark"}, {"reset": "Reset all filters"}]  

Result: Each country is displayed individually.
