Description

values: object of value, it could be to fill initialValues in formik

Example

Nb. Below is our approach. You might used your own, if you think this not suit enough for you.

import { Formik, Form } from 'formik'
import { useZeroForm, ZeroFormTypes } from '@01group/form-builder';

export const DATA = {
  name: '',
  province_id: '',
  city_id: '',
  date_of_birth: '',
};

export const generalOptions = {
  name: {
    type: 'text',
    label: 'Your name',
    isRequired: true,
  },
  province_id: {
    type: 'select',
    label: 'Province',
    placeholder: 'Select a province',
  },
  city_id: {
    type: 'select',
    label: 'City',
    placeholder: 'Select a city',
  },
};

export function Example() {
  const { fields, values } = useZeroForm({ data: DATA as ZeroFormTypes, options: generalOptions });

  return (
    <Formik
      initialValues={values}
      validationSchema={validationSchema}
      onSubmit={handleSubmit}
      enableReinitialize
    >
      <Form>
        {(fields ?? []).map((field, i) => (
          <GenerateField key={i} isReadonly={isReadonly} {...field} />
        ))}
      </Form>
    </Formik>
  )
}

export function GenerateField(props: ZeroFieldItem) {
  const inputProps = {
    id: props.name,
    name: props.name,
    label: props.label,
    placeholder: props.placeholder,
    isRequired: props.isRequired,
    isReadOnly: props.isReadonly,
  };
  const selectProps = {
    ...inputProps,
    items: props.selectOptions ?? [],
  };

  const elements: Partial<Record<Partial<ZeroFieldTypes>, JSX.Element>> = {
    select: <Select {...selectProps} />,
    text: <TextField {...inputProps} />,
    row: <Textarea {...inputProps} />,
    file: <Dropzone width="full" {...inputProps} />,
  };

  return elements[props.type] ?? <TextField {...inputProps} />;
}
