Hello! I am trying to create a Tag List filter control on my dashboard using the dashboard-next format. I would like to simply provide a Tag List filter that shows all options when clicked. Based on the documentation, it seems like that should be possible by leaving the Values field blank. However, when I try to do this, I am not able to create the filter.
This field has a null value in it, I am wondering if that is causing the issue. When I try to create the filter in the same way using a field that does not have any null values, I am able to create the filter.
However, the null value is a valid use case for filtering by my stakeholders. I would like to just be able to create the filter including all possible values including the null. Is there any way to accomplish that? The field type of my field Class Question Reason Code Name is string in the LookML.
