A lot of fields in my DB could be seen as Category, but are not. I have several fields containing few values, and filtering data on them is cumbersome as I have to type the content myself in the input field.
For example, I have a field “Priority” containing 4 values : “high” “medium” “low” and NULL
When I create a new question, and try to filter on this field, I don’t have the checkboxes that would allow me to select the priority that I want.
Could the problem be the presence of NULL values ?
If yes, is there any way to allow metabase recognize these fields as category despite the presence of NULL ?
I am using Metabase v0.24.2 on top of PostgresSQL.
