Are file extensions supported in accept attribute?

I need to accept files by extension instead of MIME type. It is supported by browsers, but react-dropzone rejects all files when i specify an extension.

@nofearOnline should be as easy as <Dropzone accept=".stl" />.

onDrop emits a js array, so use .slice(0, maxItems):

class Basic extends React.Component {
  onDrop = acceptedFiles => {
    const files = acceptedFiles.slice(0, 10) // 10 max files
  }

  render() {
    return (
      <Dropzone
        onDrop={this.onDrop}
      >
        <p>Try dropping some files here, or click to select files to upload.</p>
      </Dropzone>
    );
  }
}
