This week I'm releasing the ProcessWire Fieldtype/Inputfield module "Functional Fields" as open source in the modules directory. This was originally built in 2017 for ProFields, but hasn't required much in terms of support resources, so I thought I should release this newest version (v4) publicly. While this module is completely different from other Fieldtypes, I think it's quite useful and fulfills some needs better than other Field options. Give it a try and please let me know what you think.
For an introduction to Functional Fields, please revisit this blog post which covers all the details:

Thanks and have a great weekend!
