I've had this issue years ago and found a workaround, maybe today, there's a better solution?
The idea is to dynamically populate a form with values from another region.
I noticed the perch data option as on https://docs.grabaperch.com/te…variables-into-templates/
But inside the perch:form template we don't manage to render it:
-> This doesn't work. Is there a proper way to get a perch:form input tag that has "first edition" as value?
The second step would be to pass in 1-n values.
The third step to pass in 1-n key-value pairs.
Then it would be solved.
