Conditional logic can shorten forms, but hidden fields and branching rules also create missed requirements and difficult-to-debug submissions.

How we assessed them
We compared rule clarity, nested conditions, calculations, multipage behaviour, confirmations, notifications, integrations, accessibility, validation, saved drafts, exports, permissions, performance, pricing and route auditability.
A safer implementation workflow
- Draw the decision tree before building and state the reason for every rule
- Give fields stable names and prevent hidden fields from submitting stale answers
- Test every branch, back navigation, blank value and conflicting condition
- Check mobile layouts, keyboard use, screen readers, payment failure, notifications and exports

Common questions
Does hiding a field protect sensitive data?
No. Visibility is interface behaviour, not access control. Enforce authorisation and validation on the server.
How many conditions are too many?
When reviewers cannot explain and test every route, split the process or simplify the rules.
Should hidden fields be required?
Only when validation correctly accounts for visibility. Test every path to prevent impossible submissions.
