Is there a way to enable a Select field to use an Automatic lookup method to show distinct field values and also allow manual entry in the event the desired selection is not already present in the table? For example, a table column may already have many entries of items like Dog, Cat, Bird. The lookup method is automatic, and a hypothetical SQL select statement is:
SELECT DISTINCT Animal
FROM zoo
ORDER BY Animal
Without creating another application, how might I enter a new animal like Cow if Cow is not already a Select option?
