Dashboard filter dropdowns

How do I get dashboard filters to show a dropdown with the options.
I created a "Text or Category" filter and set it to "Dropdown". I have also set up a linked filter before that should limit the distinct values for this field to < 10.
However it doesn't show as a dropdown, I only get a search box. When I look in my db query logs I don't even see any queries to find the values to show in the filter dropdown. What am I doing wrong?
I have tried a whole bunch of different metadata types for the filtered field on the model I'm using, but none of them seem to have any effect on the filter.

Hi @ribrdb
Have a look here: https://www.metabase.com/docs/latest/troubleshooting-guide/filters#are-you-seeing-a-different-kind-of-input-widget-than-you-expected

So does that mean you can't get a dropdown for a Model created from a question?
Only fields defined in the admin ui?
What if the total number of values is > 100 but with linked filters it's < 100? Will I still get a search box?

@ribrdb Metabase can only show dropdowns based on fields from the Data Model currently, since those are the only ones scanned for values.
