defmodule Surface.Components.Form.FileInput do
@moduledoc """
Generates a file input.
It requires the given form to be configured with `multipart: true`.
All options passed via `opts` will be sent to `file_input/3`, `value` and
`class` can be set directly and will override anything in `opts`.
## Examples
```
<Form for={:user} multipart={true}>
<FileInput field={:picture} />
</Form>
```
