Dash AG Grid - creating Custom Filter Options

Dash Python

@AnnMarieW

Thanks. Are you referring to the comparator example in Ag-Grid Custom Filtering - #10 by AnnMarieW ? My understanding is that it is used for sorting.

I am trying to do this: https://www.ag-grid.com/react-data-grid/filter-set-filter-list/#supplying-filter-values

Tried

 "filterParams": {
            "filterOptions": ["empty"],
            "values": ["some_value"]
        }

, but that did not work.
Do I need filterValueGetter?
