React Hook Form Dynamic Arrays

Acerca de

This skill provides expert guidance and implementation patterns for managing dynamic form fields using React Hook Form's useFieldArray hook. It ensures robust data handling by integrating Zod schema validation, covering essential operations like adding, removing, and reordering list items while preventing common anti-patterns such as using array indexes as React keys. It is ideal for developers building complex forms like team management systems, invoice line items, or multi-level nested data structures.
