Usage Example

import React from 'react';
import Carousel from 'react-material-ui-carousel'
import { Paper, Button } from '@mui/material'

function Example(props)
{
    var items = [
        {
            name: "Random Name #1",
            description: "Probably the most random thing you have ever seen!"
        },
        {
            name: "Random Name #2",
            description: "Hello World!"
        }
    ]

    return (
        <Carousel>
            {
                items.map( (item, i) => <Item key={i} item={item} /> )
            }
        </Carousel>
    )
}

function Item(props)
{
    return (
        <Paper>
            <h2>{props.item.name}</h2>
            <p>{props.item.description}</p>

            <Button className="CheckButton">
                Check it out!
            </Button>
        </Paper>
    )
}

Next & Prev Usage

    <Carousel
        next={ (next, active) => console.log(`we left ${active}, and are now at ${next}`); }
        prev={ (prev, active) => console.log(`we left ${active}, and are now at ${prev}`); }
    >
        {...}
    </Carousel>

    // OR

    <Carousel
        next={ () => {/* Do stuff */} }
        prev={ () => {/* Do other stuff */} }
    >
        {...}
    </Carousel>

    // And so on...

Note: onChange works in a similar fashion. See Props below.

Customizing Navigation

Navigation Buttons - Customizing the default solution

These are the props that are used to directly customize the Carousel's default buttons:

• NextIcon
• PrevIcon
• navButtonsProps
• navButtonsWrapperProps
• fullHeightHover

Example #1

Say we don't like the default icons used for the next and prev buttons and want to change them to be an MUI Icon or an image of our own.

import RandomIcon from '@@mui/icons-material/Random'; // Note: this doesn't exist

<Carousel
    NextIcon={<RandomIcon/>}
    PrevIcon={<RandomIcon/>}
    // OR
    NextIcon={<img src="http://random.com/next"/>}
    PrevIcon={<img src="http://random.com/prev"/>}
>
    {...}
</Carousel>

The NextIcon and PrevIcon is of type ReactNode, meaning it can be any JSX element or a string. Note: Extra styling may be needed when using those props.

Example #2

Let's now say we don't like the default graphite background of the buttons, nor do we like the fact that it is round.
We also want to place them under the main Carousel, and finally remove the arrows and have "next" and "prev" accordingly to each button.

A very important note here, is that any styles specified by the user DO NOT OVERRIDE THE EXISTING STYLES. They work in tandem with them. That means, that if you want to change, or get rid of a CSS attribute you will have to override it or unset it. The Default styles are given at the end of this section, and are part of the code.

<Carousel
    fullHeightHover={false}     // We want the nav buttons wrapper to only be as big as the button element is
    navButtonsProps={{          // Change the colors and radius of the actual buttons. THIS STYLES BOTH BUTTONS
        style: {
            backgroundColor: 'cornflowerblue',
            borderRadius: 0
        }
    }} 
    navButtonsWrapperProps={{   // Move the buttons to the bottom. Unsetting top here to override default style.
        style: {
            bottom: '0',
            top: 'unset'
        }
    }} 
    NextIcon='next'             // Change the "inside" of the next button to "next"
    PrevIcon='prev'             // Change the "inside of the prev button to "prev"
>
    {...}
</Carousel>

Of course, extra styling to the button wrappers, or indicators might be needed to achieve exactly what we may be looking for. Note: You can also use className to change the styles externally.

Customizing the navigation buttons directly

Do directly customize/change the navigation buttons NavButton prop, that allows the user to take complete control of the components rendered as the navigation buttons. It should be used like this:

Example

import {Button} from '@mui/material';

<Carousel
    NavButton={({onClick, className, style, next, prev}) => {
        // Other logic

        return (
            <Button onClick={onClick} className={className} style={style}>
                {next && "Next"}
                {prev && "Previous"}
            </Button>
        )
    }}
>
    {...}
</Carousel>

Parameters Explanation

• onClick: The function that handles actual navigation. If you do not add this to your component, the buttons will not work.
• className: The className given by the carousel component. This is used to handle Visible/Invisible, hover, and user specified styles (e.g. from navButtonProps). Apply it to the outmost element.
• style: The style given by the carousel component. Used to give any user specified styles (e.g. from navButtonProps).
• next: Boolean value that specifies whether this is the next button.
• prev: Boolean value that specifies whether this is the prev button.

The prop value must be a function that returns a component. All parameters are optional as far as styling goes (not functionality), but it is advised you use them as shown above.
As implied, any classNames or styles specified in the navButtonsProps will only be used iff you apply the given className and style parameters.

Customizing the Indicators

There are 4 props that handle indicator customization

• IndicatorIcon
• activeIndicatorIconButtonProps
• indicatorIconButtonProps
• indicatorContainerProps

Example

Let's say we would like to change the indicator icon from a circle to a something else, for example a little house

import Home from '@mui/icons-material/Home';

<Carousel
    IndicatorIcon={<Home/>}
    // OR
    IndicatorIcon={<img src="http://random.com/home"/>}
>
    {...}
</Carousel>

The IndicatorIcon works the same way as the NextIcon and PrevIcon prop.

Example #2

Now we want to do more complex customizations. Specifically:

1. More distance between the indicator icons
2. Change the background color of the active indicator to red
3. Change the color of all indicators to blue
4. Move the indicators to the right side of the carousel
5. Move the indicators to be further away down from the carousel

We are going to use all props to style the indicators

import Home from '@mui/icons-material/Home';

<Carousel
    IndicatorIcon={<Home/>} // Previous Example
    indicatorIconButtonProps={{
        style: {
            padding: '10px',    // 1
            color: 'blue'       // 3
        }
    }}
    activeIndicatorIconButtonProps={{
        style: {
            backgroundColor: 'red' // 2
        }
    }}
    indicatorContainerProps={{
        style: {
            marginTop: '50px', // 5
            textAlign: 'right' // 4
        }

    }}
>
    {...}
</Carousel>

As before, you can use className to style the elements externally.

Default Styles

Giving the default styles in pseudo-code.

    buttonWrapper: {
        position: "absolute",
        height: "100px",
