# Dropzone

A high-quality, unstyled React dropzone primitive for drag-and-drop and click-to-select file selection.

## Demo

### Tailwind

This example shows how to implement the component using Tailwind CSS.

```tsx
/* index.tsx */
'use client';

import * as React from 'react';
import { Dropzone } from '@base-ui/react/dropzone';

export default function ExampleDropzone() {
  const [files, setFiles] = React.useState<File[]>([]);

  const appendFiles = React.useCallback((nextFiles: File[]) => {
    setFiles((prev) => [...prev, ...nextFiles]);
  }, []);

  return (
    <div className="w-full rounded-xl border border-neutral-200 bg-white p-8 text-neutral-900">
      <Dropzone.Root
        className="block rounded-xl border-2 border-dashed border-neutral-400 bg-neutral-50 px-6 py-10 text-center transition-colors hover:border-blue-500 hover:bg-blue-500/10 focus-visible:outline focus-visible:outline-2 focus-visible:outline-blue-800 data-dragging:border-blue-500 data-dragging:bg-blue-500/15 data-disabled:cursor-not-allowed data-disabled:opacity-65"
        onFilesDrop={(droppedFiles) => appendFiles(droppedFiles)}
      >
        <Dropzone.HiddenInput
          className="hidden"
          multiple
          onChange={(event) => {
            const selected = Array.from(event.currentTarget.files ?? []);
            if (selected.length > 0) {
              appendFiles(selected);
            }
            event.currentTarget.value = '';
          }}
        />
        <p className="text-sm font-semibold text-neutral-800">Drop files here</p>
        <p className="mt-1 text-xs text-neutral-600">or click to open the file picker</p>
      </Dropzone.Root>

      {files.length === 0 ? (
        <p className="mt-4 text-sm text-neutral-500">No files selected yet.</p>
      ) : (
        <ul className="mt-4 list-none space-y-2 p-0">
          {files.map((file, index) => (
            <li
              key={`${file.name}-${file.size}-${index}`}
              className="rounded-md border border-neutral-200 px-3 py-2 text-sm text-neutral-900"
            >
              {file.name}
            </li>
          ))}
        </ul>
      )}
    </div>
  );
}
```

  @media (prefers-color-scheme: dark) {
    color: oklch(65% 0 0deg);
  }
}

.list {

  list-style: none;
  padding: 0;
  display: flex;

  line-height: 1.25rem;

  @media (prefers-color-scheme: dark) {
    color: oklch(65% 0 0deg);
  }
}
```

```tsx
/* index.tsx */
'use client';

import * as React from 'react';
import { Dropzone } from '@base-ui/react/dropzone';
import styles from './index.module.css';

export default function ExampleDropzone() {
  const [files, setFiles] = React.useState<File[]>([]);

  const appendFiles = React.useCallback((nextFiles: File[]) => {
    setFiles((prev) => [...prev, ...nextFiles]);
  }, []);

  return (
    <div className={styles.container}>
      <Dropzone.Root
        className={styles.dropzone}
        onFilesDrop={(droppedFiles) => appendFiles(droppedFiles)}
      >
        <Dropzone.HiddenInput
          multiple
          onChange={(event) => {
            const selected = Array.from(event.currentTarget.files ?? []);
            if (selected.length > 0) {
              appendFiles(selected);
            }
            event.currentTarget.value = '';
          }}
        />
        <p className={styles.heading}>Drop files here</p>
        <p className={styles.hint}>or click to open the file picker</p>
      </Dropzone.Root>

      {files.length === 0 ? (
        <p className={styles.empty}>No files selected yet.</p>
      ) : (
        <ul className={styles.list}>
          {files.map((file, index) => (
            <li className={styles.item} key={`${file.name}-${file.size}-${index}`}>
              {file.name}
            </li>
          ))}
        </ul>
      )}
    </div>
  );
}
```

## Usage guidelines

- **Form controls must have an accessible name**: Provide visible text in the dropzone, or set `aria-label`/`aria-labelledby` for icon-only UIs. See [Labeling a dropzone](/react/components/dropzone.md) and the [forms guide](/react/handbook/forms.md).

## Anatomy

Import the component and assemble its parts:

```jsx title="Anatomy"
import { Dropzone } from '@base-ui/react/dropzone';

<Dropzone.Root>
  <Dropzone.HiddenInput />
  Drop files here
</Dropzone.Root>;
```

## Examples

### Labeling a dropzone

For icon-only designs, provide an explicit accessible name:

```tsx title="Icon-only dropzone"
import { Dropzone } from '@base-ui/react/dropzone';

<Dropzone.Root aria-label="Upload files">
  <Dropzone.HiddenInput />
  <UploadIcon aria-hidden />
</Dropzone.Root>;
```
