import classNames from 'classnames'

import {
  BaseForm,
  TextWidget,
  EmailWidget,

function columnsObjectFieldTemplate ({ properties, description }) {
  return (
    <div>
      <div className='columns is-multiline has-form-columns'>
        {properties.map(prop => {
          const uiSchema = prop.content.props.uiSchema
          const className = classNames('column', uiSchema['ui:column'] || 'is-12')
          return <div key={prop.content.key} className={className}>
            {prop.content}
          </div>
        })}
      </div>
      {description}

  )
}

class ColumnForm extends Component {
  render () {

      properties: {
