When no mode is specified, the component defaults to HORIZONTAL mode. Please check props for all the available options.
import React from "react"
import { Chrono } from "react-chrono";
const Home = () => {
const items = [{
title: "May 1940",
cardTitle: "Dunkirk",
cardSubtitle:"Men of the British Expeditionary Force (BEF) wade out to..",
cardDetailedText: "Men of the British Expeditionary Force (BEF) wade out to..",
media: {
type: "IMAGE",
source: {

}
}
}, ...];
return (
<div style={{ width: "500px", height: "400px" }}>
<Chrono items={items} />
</div>
)
}
To render the timeline vertically use the VERTICAL mode
<div style={{ width: "500px", height: "950px" }}>
<Chrono
items={items}
mode="VERTICAL"
/>
</div>
In VERTICAL_ALTERNATING mode the timeline is rendered vertically with cards alternating between left and right side.
<div style={{ width: "500px", height: "950px" }}>
<Chrono
items={items}
mode="VERTICAL_ALTERNATING"
/>
</div>
Play the timeline automatically with the slideShow mode. This prop enables the play button on the ui controls.
<div style={{ width: "500px", height: "950px" }}>
<Chrono
items={items}
slideShow
mode="VERTICAL_ALTERNATING"
/>

react-chrono supports three modes HORIZONTAL, VERTICAL and VERTICAL_ALTERNATING. No additional setting is required.
<Chrono items={items} mode="HORIZONTAL" />
<Chrono items={items} mode="VERTICAL" />
<Chrono items={items} mode="VERTICAL_ALTERNATING" />
| name | description | type |
|---|---|---|
| title | title of the timeline item | String |
| cardTitle | title that is displayed on the timeline card | String |
| cardSubtitle | text displayed in the timeline card | String |

{
title: "May 1940",
cardTitle: "Dunkirk",
cardSubtitle:
"Men of the British Expeditionary Force (BEF) wade out to a destroyer during the evacuation from Dunkirk.",
cardDetailedText: ["paragraph1", "paragraph2"],
}
if you have a large text to display(via cardDetailedText) and want to split the text into paragraphs, you can pass an array of strings.
each array entry will be created as a paragraph inside the timeline card.
The timeline can be navigated via keyboard.
HORIZONTAL mode use your LEFT RIGHT arrow keys for navigation.VERTICAL or VERTICAL_ALTERNATING mode, the timeline can be navigated via the UP DOWN arrow keys.To disable keyboard navigation set disableNavOnKey to true.
<Chrono items={items} disableNavOnKey />
With the scrollable prop, you can enable scrolling on both VERTICAL and VERTICAL_ALTERNATING modes.
<Chrono items={items} scrollable />
The scrollbar is not shown by default. To enable the scrollbar, pass an object with prop scrollbar to scrollable prop.
<Chrono items={items} scrollable={{scrollbar: true}} />
Both images and videos can be embedded in the timeline.
Just add the media attribute to the Timeline Item model and the component will take care of the rest.
{
title: "May 1940",
cardTitle: "Dunkirk",
media: {
name: "dunkirk beach",
source: {
url: "http://someurl/image.jpg"
},
type: "IMAGE"
}
}
Videos start playing automatically when active and will be automatically paused when not active.
Like images, videos are also automatically hidden when not in the visible viewport of the container.
{
title: "7 December 1941",
cardTitle: "Pearl Harbor",
media: {
source: {
url: "/pearl-harbor.mp4",
type: "mp4"
},
type: "VIDEO",
name: "Pearl Harbor"
}
}
To embed YouTube videos, use the right embed url.
{
title: "7 December 1941",
cardTitle: "Pearl Harbor",
media: {
source: {
url: "https://www.youtube.com/embed/f6cz9gtMTeI",
type: "mp4"
},
type: "VIDEO",
name: "Pearl Harbor"
}
}
The component also supports embedding custom content in the Timeline cards.
To insert custom content, just pass the blocked elements between the Chrono tags.
For e.g the below snippet will create 2 timeline items. Each div element is automatically converted into a timeline item and inserted into the timeline card.
The items collection is completely optional and custom rendering is supported on all 3 modes.
<Chrono mode="VERTICAL">
<div>
<p>Lorem Ipsum. Lorem Ipsum. Lorem Ipsum</p>
</div>
<div>
<img src="<url to a nice image" />
</div>
</Chrono>
The items collection will also work nicely with any custom content that is passed.
The following snippet sets the the title and cardTitle for the custom contents.
const items = [
{title: "Timeline title 1", cardTitle: "Card Title 1"},
{title: "Timeline title 2", cardTitle: "Card Title 2"}
];
<Chrono mode="VERTICAL" items={items}>
<div>
<p>Lorem Ipsum. Lorem Ipsum. Lorem Ipsum</p>
</div>
<div>
<img src="<url to a nice image" />
</div>
</Chrono>
To use custom icons in the timeline, pass in the collection of images between the chrono tags wrapped in a container.
The icons are sequentially set (i.e) the first image you pass will be used as the icon for the first timeline item and so on.
Please make sure to pass in the image collection inside a container with a special className chrono-icons. This convention is mandatory as the component uses this class name to pick the images.
<Chrono items={items} mode="VERTICAL_ALTERNATING">
<div className="chrono-icons">
<img src="image1.svg" alt="image1" />
<img src="image2.svg" alt="image2" />
</div>
</Chrono>
custom icons also works if you are rendering custom content inside the cards.
<Chrono mode="VERTICAL" items={items}>
<div>
<p>Lorem Ipsum. Lorem Ipsum. Lorem Ipsum</p>
</div>
<div>
<img src="<url to a nice image" />
</div>
<div className="chrono-icons">
<img src="image1.svg" alt="image1" />
<img src="image2.svg" alt="image2" />
</div>
</Chrono>
Slideshow can be enabled by setting the slideShow prop to true. You can also set an optional slideItemDuration that sets the time delay between cards.
setting this prop enables the play button in the timeline control panel.
<Chrono items={items} slideShow slideItemDuration={4500} />
The itemWidth prop can be used to set the width of each individual timeline sections. This setting is applicable only for the HORIZONTAL mode.
Customize colors with the theme prop.
<Chrono
items={items}
theme={{
primary: "red",
secondary: "blue",
cardBgColor: "yellow",
cardForeColor: "violet",
titleColor: "red"
}}
/>
