Form Refactorer

Refactor legacy forms to modern Redpanda UI Registry Field components with react-hook-form and Zod validation.

Core Requirements

MUST USE (Modern Pattern)

• Field component family from components/redpanda-ui/components/field
• react-hook-form for form state management
• Zod for validation schemas via zodResolver

FORBIDDEN (Legacy Patterns)

See no-legacy for prohibited patterns. Also never import Form from components/redpanda-ui/components/form.

Component Hierarchy

FieldSet              - Semantic fieldset container for related fields
├─ FieldLegend        - Title for the fieldset
├─ FieldDescription   - Description for entire fieldset
└─ FieldGroup         - Layout wrapper that stacks fields
   ├─ Field           - Individual field wrapper
   │  ├─ FieldLabel       - Label for input (use htmlFor)
   │  ├─ Input/Select/... - Form control
   │  ├─ FieldDescription - Helper text
   │  └─ FieldError       - Error message
   ├─ FieldSeparator  - Visual divider between fields
   └─ Field           - Another field

Key Patterns

Vertical field:

<Field data-invalid={!!errors.fieldName}>
  <FieldLabel htmlFor="fieldName">Label</FieldLabel>
  <Input id="fieldName" {...register("fieldName")} aria-invalid={!!errors.fieldName} />
  {errors.fieldName && <FieldError>{errors.fieldName.message}</FieldError>}
</Field>

Horizontal field (switch/checkbox):

<Field orientation="horizontal">
  <Switch id="toggle" {...register("toggle")} />
  <FieldContent>
    <FieldLabel htmlFor="toggle">Enable Feature</FieldLabel>
    <FieldDescription>Description</FieldDescription>
  </FieldContent>
</Field>

Checklist

Before completing refactoring, verify:

• All legacy form imports removed (Chakra, @redpanda-data/ui, legacy Form)
• Field components used for all fields
• FieldLabel has htmlFor matching Input id
• Errors show data-invalid on Field and aria-invalid on Input
• Yup replaced with Zod + zodResolver
• FieldSet + FieldLegend used for semantic grouping
• FieldError conditionally rendered: {errors.field && <FieldError>...
• Form submission handled via react-hook-form handleSubmit
