I just noticed that validation for dropdown select elements does not appear to be working, whether the dropdown is a taxonomy selection or a custom field.
I have a custom field of type dropdown (created with Types). I added an empty value for it in Types admin (- Select Something-). It's coming fine in CRED form but is not validating. The form would still submit even if the user does not change the default value of this dropdown.
So, to sum up. There are two issues related to select dropdowns in CRED forms:
1) If the dropdown is a taxonomy field, how to display a blank value as a first value? And how force this taxonomy field to be required.
2) If the dropdown is a custom field, how to make it required? It is already set as required in Types and also has a default blank first value (i.e. Select Something)
I hope this is clear.
