  },
  {
    key: 'robert',
    value: 'Robert',
  },
  {
    key: 'karius',
    value: 'Karius',
  },
]

render() {
  return (
    <ReactSearchBox
      placeholder="Search for John, Jane or Mary"
      data={data}
      onSelect={record => console.log(record)}
      onFocus={() => {
        console.log('This function is called when is focussed')
      }}
      onChange={value => console.log(value)}
      fuseConfigs={{
        threshold: 0.05,
      }}
      value="John"
    />
  )
