The useDropzone hook just binds the necessary handlers to create a drag 'n' drop zone. Use the getRootProps() fn to get the props required for drag 'n' drop and use them on any element. For click and keydown behavior, use the getInputProps() fn and use the returned props on an <input>.

Furthermore, the hook supports folder drag 'n' drop by default. See file-selector for more info about supported browsers.

import React from 'react';
import {useDropzone} from 'react-dropzone';

function Basic(props) {
  const {acceptedFiles, getRootProps, getInputProps} = useDropzone();
  
  const files = acceptedFiles.map(file => (
    <li key={file.path}>
      {file.path} - {file.size} bytes
    </li>
  ));

  return (
    <section className="container">
      <div {...getRootProps({className: 'dropzone'})}>
        <input {...getInputProps()} />
        <p>Drag 'n' drop some files here, or click to select files</p>
      </div>
      <aside>
        <h4>Files</h4>
        <ul>{files}</ul>
      </aside>
    </section>
  );
}

Dropzone with disabled property:

import React from 'react';
import {useDropzone} from 'react-dropzone';

function Basic(props) {
  const {acceptedFiles, getRootProps, getInputProps} = useDropzone({
    disabled: true
  });

  const files = acceptedFiles.map(file => (
    <li key={file.name}>
      {file.name} - {file.size} bytes
    </li>
  ));

  return (
    <section className="container">
      <div {...getRootProps({className: 'dropzone disabled'})}>
        <input {...getInputProps()} />
        <p>Drag 'n' drop some files here, or click to select files</p>
      </div>
      <aside>
        <h4>Files</h4>
        <ul>{files}</ul>
      </aside>
    </section>
  );
}
