The Syncfusion React Carousel component is a powerful, fully-featured carousel for displaying images, content, or any sequential items with automatic or manual transitions. It supports multiple animation effects, customizable indicators and navigators, keyboard navigation, and comprehensive accessibility features.

When to Use This Skill

Implement the Carousel component when you need to:

• Create rotating image galleries with smooth transitions
• Build slideshow presentations with navigation controls
• Display product carousels for e-commerce sites
• Implement testimonial sliders with indicators
• Build content carousels with auto-play functionality
• Support touch/swipe navigation on mobile devices
• Display items with accessibility compliance (WCAG 2.2, Section 508)

Component Overview

The Carousel component manages:

• Visual Display: Renders one active slide with customizable templates
• Navigation: Previous/next buttons with multiple visibility modes
• Indicators: Show current position with multiple indicator types (dots, fractions, progress bars)
• Animations: Smooth slide transitions with fade, slide, or custom effects
• Interaction: Auto-play, manual swipe, keyboard navigation
• Accessibility: Full ARIA support, keyboard shortcuts, screen reader compatibility

Core imports:

import { CarouselComponent, CarouselItemsDirective, CarouselItemDirective } from "@syncfusion/ej2-react-navigations";

Quick Start Example

Minimal working carousel with 5 images:

import { CarouselComponent, CarouselItemsDirective, CarouselItemDirective } from "@syncfusion/ej2-react-navigations";import * as React from "react";
const App = () => {  return (    <div className='control-container'>      <CarouselComponent>        <CarouselItemsDirective>          <CarouselItemDirective template='<figure class="img-container"><img src="url" alt="cardinal" style="height:100%;width:100%;" /><figcaption class="img-caption">Cardinal</figcaption></figure>' />          <CarouselItemDirective template='<figure class="img-container"><img src="url" alt="kingfisher" style="height:100%;width:100%;" /><figcaption class="img-caption">Kingfisher</figcaption></figure>' />          <CarouselItemDirective template='<figure class="img-container"><img src="url" alt="toucan" style="height:100%;width:100%;" /><figcaption class="img-caption">Toucan</figcaption></figure>' />          <CarouselItemDirective template='<figure class="img-container"><img src="url" alt="warbler" style="height:100%;width:100%;" /><figcaption class="img-caption">Warbler</figcaption></figure>' />          <CarouselItemDirective template='<figure class="img-container"><img src="url" alt="bee-eater" style="height:100%;width:100%;" /><figcaption class="img-caption">Bee-eater</figcaption></figure>' />        </CarouselItemsDirective>      </CarouselComponent>    </div>  );}
export default App;

Common Patterns

Pattern 1: Auto-Play Gallery with Indicators and Navigators

<CarouselComponent autoPlay={true} showIndicators={true} buttonsVisibility="Visible">  <CarouselItemsDirective>    {/* items */}  </CarouselItemsDirective></CarouselComponent>

Pattern 2: Data-Driven Carousel with Dynamic Content

const itemTemplate = (props: any): JSX.Element => {  return <img src={props.imageUrl} alt={props.title} />;}
<CarouselComponent dataSource={carouselData} itemTemplate={itemTemplate} />

Pattern 3: Carousel with Custom Navigation Buttons

const nextButtonTemplate = (props: any): JSX.Element => {  return <ButtonComponent iconCss="e-icons e-chevron-right" />;}
<CarouselComponent nextButtonTemplate={nextButtonTemplate} />

Pattern 4: Touch-Enabled Mobile Carousel

<CarouselComponent   enableTouchSwipe={true}   swipeMode={CarouselSwipeMode.Touch & CarouselSwipeMode.Mouse}  pauseOnHover={true}>  {/* items */}</CarouselComponent>
