FilterValuesHandler

Since v0.2.7

Async handler for fetching unique filter values from a server.

For server-side datasets where not all values are available locally, this handler is called when the filter panel opens to fetch all possible values for the column.

type FilterValuesHandler = (field: string, column: ColumnConfig) => Promise<unknown[]>

Example

valuesHandler: async (field, column) => {
  const response = await fetch(`/api/distinct/${field}`);
  return response.json(); // ['Engineering', 'Marketing', 'Sales', ...]
}
