Populating items in React Carousel component

30 Jan 202321 minutes to read

In the Carousel, slides can be rendered in two ways as follows,

Populating items using carousel item
Populating Items using data source

Populating items using carousel item

When rendering the Carousel component using items binding, you can assign templates for each item separately or assign a common template to each item. You can also customize the slide transition interval for each item separately. The following example code depicts the functionality as item property binding.

index.jsx
index.tsx
import { CarouselComponent, CarouselItemsDirective, CarouselItemDirective } from "@syncfusion/ej2-react-navigations";
import * as React from "react";
import * as ReactDOM from "react-dom";
const App = () => {
    return (<div className='control-container'>
      <CarouselComponent>
        <CarouselItemsDirective>
          <CarouselItemDirective template='<figure class="img-container"><img src="https://ej2.syncfusion.com/products/images/carousel/cardinal.png" alt="cardinal" style="height:100%;width:100%;" /><figcaption class="img-caption">Cardinal</figcaption></figure>'/>
          <CarouselItemDirective template='<figure class="img-container"><img src="https://ej2.syncfusion.com/products/images/carousel/hunei.png" alt="kingfisher" style="height:100%;width:100%;" /><figcaption class="img-caption">Kingfisher</figcaption></figure>'/>
          <CarouselItemDirective template='<figure class="img-container"><img src="https://ej2.syncfusion.com/products/images/carousel/costa-rica.png" alt="keel-billed-toucan" style="height:100%;width:100%;" /><figcaption class="img-caption">Keel-billed-toucan</figcaption></figure>'/>
          <CarouselItemDirective template='<figure class="img-container"><img src="https://ej2.syncfusion.com/products/images/carousel/kaohsiung.png" alt="yellow-warbler" style="height:100%;width:100%;" /><figcaption class="img-caption">Yellow-warbler</figcaption></figure>'/>
          <CarouselItemDirective template='<figure class="img-container"><img src="https://ej2.syncfusion.com/products/images/carousel/bee-eater.png" alt="bee-eater" style="height:100%;width:100%;" /><figcaption class="img-caption">Bee-eater</figcaption></figure>'/>
        </CarouselItemsDirective>
      </CarouselComponent>
    </div>);
}
const root = ReactDOM.createRoot(document.getElementById('element'));
root.render(<App />);
import { CarouselComponent, CarouselItemsDirective, CarouselItemDirective } from "@syncfusion/ej2-react-navigations";
import * as React from "react";
import * as ReactDOM from "react-dom";

const App = () => {
  return (
    <div className='control-container'>
      <CarouselComponent>
        <CarouselItemsDirective>
          <CarouselItemDirective template='<figure class="img-container"><img src="https://ej2.syncfusion.com/products/images/carousel/cardinal.png" alt="cardinal" style="height:100%;width:100%;" /><figcaption class="img-caption">Cardinal</figcaption></figure>' />
          <CarouselItemDirective template='<figure class="img-container"><img src="https://ej2.syncfusion.com/products/images/carousel/hunei.png" alt="kingfisher" style="height:100%;width:100%;" /><figcaption class="img-caption">Kingfisher</figcaption></figure>' />
          <CarouselItemDirective template='<figure class="img-container"><img src="https://ej2.syncfusion.com/products/images/carousel/costa-rica.png" alt="keel-billed-toucan" style="height:100%;width:100%;" /><figcaption class="img-caption">Keel-billed-toucan</figcaption></figure>' />
          <CarouselItemDirective template='<figure class="img-container"><img src="https://ej2.syncfusion.com/products/images/carousel/kaohsiung.png" alt="yellow-warbler" style="height:100%;width:100%;" /><figcaption class="img-caption">Yellow-warbler</figcaption></figure>' />
          <CarouselItemDirective template='<figure class="img-container"><img src="https://ej2.syncfusion.com/products/images/carousel/bee-eater.png" alt="bee-eater" style="height:100%;width:100%;" /><figcaption class="img-caption">Bee-eater</figcaption></figure>' />
        </CarouselItemsDirective>
      </CarouselComponent>
    </div>
  );
}

const root = ReactDOM.createRoot(document.getElementById('element'));
root.render(<App />);

Populating Items using data source

When rendering the Carousel component using data binding, you can assign a common template only for all items using the itemTemplate property. You cannot set the interval for each item. The following example code depicts the functionality as data binding.

index.jsx
index.tsx
import { CarouselComponent } from "@syncfusion/ej2-react-navigations";
import { useMemo } from "react";
import * as React from "react";
import * as ReactDOM from "react-dom";

const App = () => {
const productItems = useMemo(() => [
{ ID: 1, Name: "Cardinal", imageName: 'cardinal' },
{ ID: 2, Name: "Kingfisher", imageName: 'hunei' },
{ ID: 3, Name: "Keel-billed-toucan", imageName: 'costa-rica' },
{ ID: 4, Name: "Yellow-warbler", imageName: 'kaohsiung' },
{ ID: 5, Name: "Bee-eater", imageName: 'bee-eater' }
], []);

const itemTemplate = (props) => {
  return <figure className="img-container"><img src={"https://ej2.syncfusion.com/products/images/carousel/" + props.imageName + ".png"} alt={props.Name} style= /><figcaption className="img-caption">{props.Name}</figcaption></figure>;
}

return (
<div className='control-container'>
<CarouselComponent dataSource={productItems} itemTemplate={itemTemplate}></CarouselComponent>
</div>
);
}

const root = ReactDOM.createRoot(document.getElementById('element'));
root.render(<App />);
import { CarouselComponent } from "@syncfusion/ej2-react-navigations";
import { useMemo } from "react";
import * as React from "react";
import * as ReactDOM from "react-dom";

const App = () => {
const productItems: Record<string, string | number>[] = useMemo(() => [
{ ID: 1, Name: "Cardinal", imageName: 'cardinal' },
{ ID: 2, Name: "Kingfisher", imageName: 'hunei' },
{ ID: 3, Name: "Keel-billed-toucan", imageName: 'costa-rica' },
{ ID: 4, Name: "Yellow-warbler", imageName: 'kaohsiung' },
{ ID: 5, Name: "Bee-eater", imageName: 'bee-eater' }
], []);

const itemTemplate = (props: any): JSX.Element => {
  return <figure className="img-container"><img src={"https://ej2.syncfusion.com/products/images/carousel/" + props.imageName + ".png"} alt={props.Name} style= /><figcaption className="img-caption">{props.Name}</figcaption></figure>;
}

return (
<div className='control-container'>
<CarouselComponent dataSource={productItems} itemTemplate={itemTemplate}></CarouselComponent>
</div>
);
}

const root = ReactDOM.createRoot(document.getElementById('element'));
root.render(<App />);

Selection

The Carousel items will be populated from the first index of the Carousel items and can be customized using the following ways,

Select an item using the property.
Select an item using the method.

Select an item using the property

Using the selectedIndex property of the Carousel component, you can set the slide to be populated at the time of initial rendering else you can switch to the particular slide item.

index.jsx
index.tsx
import { CarouselComponent, CarouselItemsDirective, CarouselItemDirective } from "@syncfusion/ej2-react-navigations";
import * as React from "react";
import * as ReactDOM from "react-dom";
const App = () => {
    return (<div className='control-container'>
      <CarouselComponent selectedIndex={3}>
        <CarouselItemsDirective>
          <CarouselItemDirective template='<figure class="img-container"><img src="https://ej2.syncfusion.com/products/images/carousel/cardinal.png" alt="cardinal" style="height:100%;width:100%;" /><figcaption class="img-caption">Cardinal</figcaption></figure>'/>
          <CarouselItemDirective template='<figure class="img-container"><img src="https://ej2.syncfusion.com/products/images/carousel/hunei.png" alt="kingfisher" style="height:100%;width:100%;" /><figcaption class="img-caption">Kingfisher</figcaption></figure>'/>

          <CarouselItemDirective template='<figure class="img-container"><img src="https://ej2.syncfusion.com/products/images/carousel/bee-eater.png" alt="bee-eater" style="height:100%;width:100%;" /><figcaption class="img-caption">Bee-eater</figcaption></figure>'/>
        </CarouselItemsDirective>
      </CarouselComponent>
    </div>);
}
const root = ReactDOM.createRoot(document.getElementById('element'));
root.render(<App />);

        </CarouselItemsDirective>
      </CarouselComponent>
    </div>
  );
}

const root = ReactDOM.createRoot(document.getElementById('element'));
root.render(<App />);

Select an item using the method

Using the prev or next public method of the Carousel component, you can switch the current populating slide to a previous or next slide.

index.jsx

const App = () => {
  const carouselRef = useRef<CarouselComponent>(null);
  const prevBtnClick = () => {
    carouselRef.current.prev();
  }

  const nextBtnClick = () => {
    carouselRef.current.next();
  }

  return (
    <div>
      <ButtonComponent className="e-btn" cssClass="e-info" onClick={prevBtnClick}>Previous</ButtonComponent>
      <ButtonComponent className="e-btn" cssClass="e-info" onClick={nextBtnClick}>Next</ButtonComponent>

Partial visible slides

The Carousel component supports to show one complete slide and a partial view of adjacent (previous and next) slides at the same time. You can enable or disable the partial slides using the partialVisible property.

Slide animation only applicable if the partialVisible is enabled.

The last slide will be displayed as a partial slide at the initial rendering when the loop and partialVisible properties are enabled.

The previous slide is not displayed at the initial rendering when the loop is disabled.

The following example code depicts the functionality of partialVisible and without loop functionalities.
