I need a way that can be supported by Formidable that can populate a checkbox field or other dropdown types with data from a MYSQL table.

The criteria for this request

[1] The data is outside of the standard WordPress Tables

[2] The data is not derived from other data already on the form

There are reasons in making this request as opposed to hard coding the options

[a] The data i have is subject to change as it is based on aviation data

[b] i should not have to hard code 232 country codes that are aviation specific or 9000 airport codes

Any help would be gratefully appreciated as Formidable Support are apparently declining to help as they claim what I want is Custom code and to copy an example in the documentation that is similar but they class that as custom code as well so its a catch 22 situation .

Basically at the end of the day if I cannot get help to get this working then Formidable Forms has failed and I will seek a refund and give an honest review
