Whether to collapse the range selector buttons into a dropdown when there is not enough room to show everything in a single row, instead of dividing the range selector into multiple rows. Can be one of the following:

- `always`: Always collapse
- `responsive`: Only collapse when there is not enough room
- `never`: Never collapse
