Field as Primary Wrapper

Comprehensive guide showing Field as the recommended pattern for wrapping form inputs with React Hook Form integration.

Field as Primary Wrapper Pattern

The Field component is the recommended way to wrap form inputs. It provides:

Labels - Properly associated with inputs via htmlFor
Helper text - Guidance linked via aria-describedby
Error messages - With role="alert" for accessibility
Required/Optional indicators - Visual and semantic
Consistent spacing - Uniform form layout

Integration Patterns

Native inputs (Input, Textarea):

<Field label="Email" errorText={errors.email?.message}>
  <Input {...register('email')} />
</Field>

Controlled components (Select, Checkbox, Switch, Slider):

<Field label="Country" errorText={errors.country?.message}>
  <Controller
    name="country"
    control={control}
    render={({ field }) => (
      <Select value={field.value} onValueChange={field.onChange}>
        ...
      </Select>
    )}
  />
</Field>
