Field Arrays, Dynamic Forms, Validation Flows
Create field arrays, show/hide sections based on values, and implement touched/errors for a clear validation flow.
Why these patterns?
Goal: Scale forms without pain.
- Field arrays (add/remove rows)
- Dynamic sections (show by value)
- Validation flow: touched, submit, errors
Principles for large forms
- Single source of truth for form data
- Stable keys for dynamic rows
- Touched marks user-visited fields
- Validate on submit; optionally on blur
