How to Filter NULL Values within a Control linked to a Parameter

I have a field that has “NULL” in the values, when I create a parameter and filter to this field the “NULL” values disappear from the dropdown. Is there a way to allow the user to filter down to “NULL” values from a drop down control that is linked to a Parameter?

Hello @stormsarah, I think the parameter might auto-remove null values since it won’t display it as an option within the select. I have a thought though, that if you went into the “More formatting options” of the field that the parameter is connected to, opened the Null values section and entered NULL into the Show custom box, that it might resolve your issue. Let me know if that works!

Otherwise, you could try creating a control based off of the filter and in the filter requirements select “include nulls” from the dropdown.

Thank you! I was able to get this working.
