Behavior Notes

• Rules use source field name only. Do not use DC syntax.
• Comparison is string-based.
• Hidden targets are:
  • force-hidden on frontend,
  • disabled before submit,
  • excluded from validation pass.
• Works in both builder preview and published pages.

Current Limits

• Captcha elements (reCAPTCHA/hCaptcha/Turnstile) are fully usable in forms, but are not supported as conditional-logic targets in this addon version.
• Third-party custom elements are unsupported unless they follow standard name flow.
