   * The `TextField` is a convenience wrapper for the most common cases (80%).
   * It cannot be all things to all people, otherwise the API would grow out of control.
   *
   * ## Advanced Configuration
   *
   * It's important to understand that the text field is a simple abstraction
   * on top of the following components:
   *
   * - [FormControl](/api/form-control/)
   * - [InputLabel](/api/input-label/)
   * - [FilledInput](/api/filled-input/)
   * - [OutlinedInput](/api/outlined-input/)
   * - [Input](/api/input/)
   * - [FormHelperText](/api/form-helper-text/)
   *
   * If you wish to alter the properties applied to the `input` element, you can do so as follows:
   *
   * ```jsx
   * const inputProps = {
   *   step: 300,
   * };
   *
   * return <TextField id="time" type="time" inputProps={inputProps} />;
   * ```
   *
   * For advanced cases, please look at the source of TextField by clicking on the
   * "Edit this page" button above. Consider either:
   *
   * - using the upper case props for passing values directly to the components
   * - using the underlying components directly as shown in the demos
