Simple form setup

function Form() {
    return (
        <FormContainer
            defaultValues={{name: ''}}
            onSuccess={data => console.log(data)}
        >
            <TextFieldElement name="name" label="Name" required/>
        </FormContainer>
    )
}

Typesafe form setup

  function Form() {
    const {control, handleSubmit} = useForm({
      defaultValues: {
        name: '',
        auto: '',
        check: false
      },
    })
    const options = [
      {id: 'one', label: 'One'},
      {id: 'two', label: 'Two'},
      {id: 'three', label: 'Three'},
    ]
    return (
        <form onSubmit={handleSubmit((data) => console.log(data))} noValidate>
          <Stack spacing={2}>
            <TextFieldElement
              name={'name'}
              label={'Name'}
              control={control}
              required
              fullWidth
            />
            <AutocompleteElement
              name={'auto'}
              label={'Autocomplete'}
              control={control}
              options={options}
            />
            <CheckboxElement name={'check'} label={'Check'} control={control} />
            <Button type={'submit'} color={'primary'}>
              Submit
            </Button>
          </Stack>
        </form>
    )
  }

You can have a look at all different possibilities to use forms at following code examples

FormContainer creates formContext

The <FormContainer /> wires up a form and you can create sub-components which either make use of useFormContext() | useWatch() to react to form values.

Demo

Check out Storybook: Demo

You will find examples and use cases.

With Datepicker

If you are using the DatepickerElement keep in mind that you have to wrap your form with a provider:

Examples for Dayjs or DateFns provider (used in the demo):

• DateFns
• Dayjs

Troubleshooting

Issues if context is undefined (useWatch)

For convenient reasons this package is re-exporting react-hook-form which is especially required if you have context issues of React.

import {useWatch} from 'react-hook-form-mui' // instead of react-hook-form

const MySubmit = () => {
    const value = useWatch('fieldName')
    return (
        <Button disabled={!value}>Submit</Button>
    )
}

Bundle

This project uses tsup to wrap the package for npm.
