I want to have a data-type for 3 values:
Boolean fields only cover true/false. Is there a way to activate "unknown"? Workaround would be a dropdown.
Thanks for input and ideas!
In 7.7 you can create any field type you want by code, I can recommend the following documentation on it:
I'm not sure about your use case, if a fully custom field type is not necessarily needed I would go for either a radio button field or dropdown field like you suggested.
thanks for the documentation. The radio button does the job, thx.
