thank you for response.
no!
those FIELDS are already incl as default i believe.
i said DATASETS.
specifically pre-loaded datasets.
i gave the existing example in your form of the COUNTRY Field.
so why is my question so misunderstood?
PRE-LOADED DATASETS for various relevant FIELDS, eg State, Postcode,
actually, functionally, it is exactly the same as ‘drop-down’ options: the difference is that in these cases, the dataset, the number of possible options is so large and specific, that usually someone or some company separately creates, eg, as per your form, a pre-loaded pre-populated, list of all possible Countries, or some desired sub-set.
the extra ‘wrinkle’ with Fields such as State and Postcode, is that they need to be linked to the selected Country value so the State Field shows only those States relevant to that Country.
why do i have to explain all this?
