# InputFile
To implement InputFile component into your project you'll need to add the import:
```jsx
import InputFile from "@kiwicom/orbit-components/lib/InputFile";
```
After adding import into your project you can use it simply like:
```jsx
<InputFile />
```

## Functional specs
* The `error` prop overwrites the `help` prop, due to higher priority.

* If you pass some `string` into **placeholder** it will be used as its placeholder.

* If you pass some `string` into **title** it will be used for button content.

* `ref` can be used for example auto-focus the elements immediately after render.
```jsx
class Component extends React.PureComponent<Props> {

  componentDidMount() {
    this.ref.current && this.ref.current.focus();
  }

  ref: { current: React$ElementRef<*> | null } = React.createRef();

  render() {
    return (
      <InputFile ref={this.ref} />
    )
  }
}
```
