  return (
    <AliceCarousel mouseTracking items={items} />
  );
}
```

#### Options
- `activeIndex` : Number, default `0` - Set carousel at the specified position.
- `animationDuration`: Number, default `400` - Set duration of animation.
- `animationEasingFunction`: String or [Function](https://developer.mozilla.org/ru/docs/Web/CSS/animation-timing-function), default `ease` - Property sets how an animation progresses through the duration of each cycle.
- `animationType`: String(`slide`, `fadeout`), default `slide` - Set type of animation.
- `autoHeight`: Boolean, default `false` - Set auto height mode.
- `autoWidth`: Boolean, default `false` - Set auto width mode.
- `autoPlay`: Boolean, default `false` - Set autoplay mode.
- `autoPlayControls`: Boolean, default `false` - Show/hide `play/pause` buttons.

- `autoPlayInterval`: Number, default `400` - Set autoplay interval value.
- `autoPlayStrategy`: String(`default`, `action`, `all`, `none`) - Set a strategy for autoplay mode
    * `default` - pause automatic playback on the hover
    * `action` - stop automatic playback if user action was detected
    * `all` - merge `default` && `action` strategies
    * `none` - ignore any user actions when the `autoPlay` property was specified
- `controlsStrategy`: String (`default`, `responsive`, `alternate` or combined string `"default,alternate"`) - Set a strategy for gallery controls.
    * `default` - use controls as is
    * `alternate` - show each dot for each slide
    * `responsive` - navigation will be hidden if the number of gallery elements is equal to the number of items in the slide.
- `disableButtonsControls`: Boolean, default `false` - Disable buttons controls.
- `disableDotsControls`: Boolean, default `false` - Disable dots controls.
- `disableSlideInfo`: Boolean, default `true` - Disable information about current slide.
- `infinite`: Boolean, default `false` - Set infinite mode.
- `innerWidth`: Number, default `0` - Set a static value for a breakpoint(`key`) of the "responsive" property. For example, if you can't use 'window.innerWidth' during SSR.
- `items`: Array, default `undefined`  - Set gallery items, preferable to use this property instead of children.
- `keyboardNavigation`: Boolean, default `false`  - Enable keyboard navigation
    * `ArrowLeft` - go to the prev slide
    * `ArrowRight` - go to the next slide
    * `Space` - run/stop autoplay mode if `autoPlay` property is equal `true`
- `mouseTracking`: Boolean, default `false`  - Enable mouse drag animation.
- `paddingLeft`: Number, default `0`  - Set the gallery offset from the left.
- `paddingRight`: Number, default `0`  - Set the gallery offset from the right.
- `renderKey`: Number, default `undefined`  - Auxiliary property, allows call the render method without changing the state inside the gallery instance.
- `responsive`: Object, default `undefined` - Set number of items in the slide. The key is the breakpoint (default is the result of: () => window.innerWidth or `innerWidth` property if the last presented).
    ```js
        {
          0: {
              items: 1,
          },
          1024: {
              items: 3
          }
        }
    ```

- `renderDotsItem(e: DotsItem)`: Rendering function - create a custom component.
- `renderPrevButton({ isDisabled })`: Rendering function - create a custom component.
- `renderNextButton({ isDisabled })`: Rendering function - create a custom component.
