Usage

import React, { Component, createRef } from 'react'

import Form from 'formify-react'
import 'formify-react/dist/index.css'

import { formConstants } from './config'

const budgetData = [
  { value: 5000, label: '$5000' },
  { value: 15000, label: '$15000' },
  { value: 25000, label: '$25000' },
  { value: 35000, label: '$35000' },
  { value: 50000, label: '$50000' }
]

class Example extends Component {
  formRef = createRef()

  handleSave = () => {
    const { current } = this.formRef
    const form = current.getFormData()
    if (form.isFormValid) {
      console.log(form.formData)
    }
  }

  handleSubmit = ({ formData, isFormValid }) => {
    if (isFormValid) {
      console.log(formData)
    }
  }

  render() {
    return (
      <div>
        <Form
          model={formConstants}
          ref={this.formRef}
          data={{ budget: budgetData }}
          onSubmit={this.handleSubmit}
        />
        <button onClick={this.handleSave}>Save</button>
      </div>
    )
  }
}

getFormData() returns an object of {isFormValid, formData}. Same object will be returned if you use onChange function to get latest change while you update any field. getFormData is only be accessible when you use ref.

New Update:- Now you can pass onSubmit callback function to enable native form submit (with pressing enter);
