Your form stays short because it only shows what matters. When an answer calls for a follow-up, the right field appears; the rest wait quietly until they’re needed.
Say a support form asks whether the issue is billing or technical. Pick billing and the invoice fields show up; pick technical and the device and version questions take their place. You build the rule once, matching on a single answer or on several conditions combined with all-or-any, and Air Fill handles the reveal from there.
The person filling it out gets a form that responds to them, and you get clean records without fields that never applied cluttering the way.
