Filters in Knowi provide you with two options of how to filter the data shown to the user:
Filter on top of the results from the underlying query (default).
Pass in filter values/ids into the underlying queries using Runtime parameters in the query.
If a query uses Runtime parameters and a Label is specified, they are automatically surfaced at the dashboard or widget level filters. Additionally, the picklist can be populated with values from another dataset.
Please refer to the documentation on Runtime Parameters for more details.
