I'm using Sprout Reports, which makes this reference:
Use the Form Macros supported by the Craft CP to keep consistent with the Craft UI. Sprout Reports will import the Craft CP Form Macros. Your Settings Template can look like this where the imported forms variable includes all Craft form macros defined in craft/app/templates/_includes/forms.html
Where in the world do I find this information? And is it documented anywhere?
My inquiry was prompted by needing to know how to make a form field selection required.
