## Import

Each screen has its own set of hooks and methods. The SDK supports **partial import** and **root import** for each screen.

* Using partial import allows you to include only the code you need for your specific use case.
* Using root import allows you to load all screens from a single bundle, which is useful when you want a unified build to handle all possible screens.

```jsx Import Example theme={null}
// root import
import { useLoginPasswordlessEmailCode } from '@auth0/auth0-acul-react';

// partial import
import {
  useLoginPasswordlessEmailCode,
  // Context hooks
  useUser,
  useTenant,
  useBranding,
  useClient,
  useOrganization,
  usePrompt,
  useScreen,
  useTransaction,
  useUntrustedData,
  // Common hooks
  useCurrentScreen,
  useAuth0Themes,
  useErrors,
  // Utility hooks
  useChangeLanguage,
  useResend,
  // Methods
  submitCode,
  resendCode,
  switchConnection,
} from '@auth0/auth0-acul-react/login-passwordless-email-code';

function EmailCodeForm() {
  const { submitCode } = useLoginPasswordlessEmailCode();
  return (
    <button onClick={() => submitCode({ code: '123456' })}>
      Verify Code
    </button>
  );
}
```
