Field

A controlled form field component.

Field is a complete functional form control that renders a specific field type based on the data type used. It handles the field state, renders a label, the input, help text, error messages

Import#

  • Field: The wrapper component that controls context, state and manages rendering field types.
import { Field } from '@saas-ui/react'

Usage#

The Field is a controlled component and should aways be wrapped with Form, as it depends on the form context.

Build in field types#

Build in field types are text, textarea, number, password, select, native-select, radio, checkbox, switch, pin. Any other type will fallback to a regular HTML input element. Eg: email will render as a InputField with the type set to email.

      <FormLayout>
        <Field type="text" name="name" label="Name" />


        <Field type="email" name="email" label="Email" />
      </FormLayout>
    </Form>
  )
}

          type="number"
          name="amount"
          label="Amount"
          value="10"
          min="0"
          max="10"
        />
      </FormLayout>
    </Form>
  )
}

Advanced#

Creating your own fields.#

// form.tsx
import { createForm, createField } from '@saas-ui/react'


import ReactSelect from 'react-select'


const ReactSelectField = createField(ReactSelect, {
  isControlled: true,
})


export const Form = createForm({
  fields: {
    'react-select': ReactSelectField,
  },
})

Overriding default fields.#

You can override any of the build in types by registering a field on the corresponding key.

// form.tsx
import { createForm, createField } from '@saas-ui/react'


import ReactSelect from 'react-select'


const ReactSelectField = createField(ReactSelect, {
  isControlled: true,
})


export const Form = createForm({
  fields: {
    select: ReactSelectField,
  },
})
