Material-UI: Toggle Accordion by simply clicking on the icon

Material-UI: Toggle Accordion by simply clicking on the icon

I've set up an Accordion feature for my latest project, but I'm running into a small issue. Right now, the panel expands whenever any part of it is clicked, but I'd like it to only expand when the specific expand icon is clicked. Is there a way to customize this behavior?

Here's the code snippet:

import React from "react";
import ExpandMoreIcon from "@material-ui/icons/ExpandMore";
import Accordion from "@material-ui/core/Accordion";
import AccordionDetails from "@material-ui/core/AccordionDetails";
import Typography from "@material-ui/core/Typography";
import AccordionSummary from "@material-ui/core/AccordionSummary";

export default function App() {
return (
    <div style={{}}>
    <h4>How to create Accordion in ReactJS?</h4>
    <Accordion style={{ width: 400}}>
        <AccordionSummary 
         expandIcon={<ExpandMoreIcon />}
         aria-controls="panel1a-content"
        >   
          <div>Click to Expand</div>
        </AccordionSummary>
        <AccordionDetails>
        <Typography>Greetings of the day :)</Typography>
        </AccordionDetails>
    </Accordion>
    </div>
);
}

Answer №1

If you're looking to achieve a specific functionality that doesn't have a direct public API, there's a workaround using this handy CSS technique:

Method 1

<AccordionSummary
  sx={{
    pointerEvents: "none"
  }}
  expandIcon={
    <ExpandMoreIcon
      sx={{
        pointerEvents: "auto"
      }}
    />
  }
>

Method 2

const useStyles = makeStyles({
  summary: {
    pointerEvents: 'none',
  },
  icon: {
    pointerEvents: 'auto',
  },
});

<AccordionSummary
  className={classes.summary}
  expandIcon={<ExpandMoreIcon className={classes.icon} />}
>
  <Typography>Accordion 1</Typography>
</AccordionSummary>

Indeed, this is the way to go

1- Establishing our custom state with a handler:

  const [expand, setExpand] = React.useState(false);
  const toggleAcordion = () => {
    setExpand((prev) => !prev);
  };

2- Integrating our state into the Accordion:

<Accordion expanded={expand} style={{ width: 400 }}>

3- Implementing onClick for the icon:

    <AccordionSummary
      expandIcon={<ExpandMoreIcon />}
      aria-controls="panel1a-content"
      IconButtonProps={{
        onClick: toggleAcordion
      }}
    >

UPDATE: Clarification: The Material-UI Accordion comes with its own state (open or close) and click handler. In the approach above, we create our personal state and override the Material-UI Accordion state using the prop expanded, while adding an event listener onClick to the icon button through the IconButtonProps prop. Our event listener will open or close the Accordion by toggling our state.

NOTE: It's important to note that the code provided does not modify the cursor pointer styling.

To ensure proper functionality in version 5 and handle the mouse cursor:

1- Establish a custom state with a handler function:

const [isAccordionOpen, setAccordionOpen] = React.useState(false);

2- Integrate the created state into the Accordion component and enable toggling on click:

<Accordion expanded={isAccordionOpen}>
    <AccordionSummary
      expandIcon={
        <ExpandMoreIcon
          style={{ cursor: 'pointer' }}
          onClick={() => setAccordionOpen(!isAccordionOpen)} />
      }
      sx={{ cursor: 'unset !important' }}

Unfortunately, none of the suggested solutions resolved my issue. I ended up using the e.stopPropagation() method within the onClick event of the icon to resolve the problem after invoking the toggle function.

Here's how I implemented it:

import React from "react";
import ExpandMoreIcon from "@material-ui/icons/ExpandMore";
import Accordion from "@material-ui/core/Accordion";
import AccordionDetails from "@material-ui/core/AccordionDetails";
import Typography from "@material-ui/core/Typography";
import AccordionSummary from "@material-ui/core/AccordionSummary";

export default function App() {
return (
    <div style={{}}>
    <h4>How to create Accordion in ReactJS?</h4>
    <Accordion style={{ width: 400}}>
        <AccordionSummary 
         expandIcon={<ExpandMoreIcon />}
         aria-controls="panel1a-content"
        >   
          <div ><img src='yourIcon' onClick={(e) => { toggleAccordion(); e.stopPropagation() }} /></div>
        </AccordionSummary>
        <AccordionDetails>
        <Typography>Greetings of the day :)</Typography>
        </AccordionDetails>
    </Accordion>
    </div>
);
}

One option to consider is toggling the expanded state in an Accordion component:

function Container(props) {
  const [isExpanded, setExpanded] = React.useState(false);
  const toggleAccordion = () => {
    setExpanded((prevExpanded) => !prevExpanded);
  };
  return (
    <React.Fragment>
      <Accordion expanded={isExpanded}>
        <AccordionSummary
          expandIcon={<ExpandMoreIcon onClick={toggleAccordion} />}
          aria-controls="panel1a-content"
          id="panel1a-header"
        >
          <Typography></Typography>
        </AccordionSummary>
        <AccordionDetails>
        </AccordionDetails>
      </Accordion>

Here is a solution I came up with for using the onChange property in Accordion (TypeScript version):

interface Props {
  information: {id: number, title: string, description: string}
}

const CustomAccordionComponent: React.FC<Props> = ({ information }) => {
  const [expanded, setExpanded] = useState<number | false>(false) 

  const handleExpansion = (id: number) => (_e: React.SyntheticEvent, isExpanded: boolean) => {
    setExpanded(isExpanded ? id : false)
  }

  return (
    <>
      <Accordion expanded={expanded === information.id} onChange={handleExpansion(information.id)}>
        <AccordionSummary expandIcon={<ExpandMoreIcon/>}>
          {information.title}
        </AccordionSummary>
        <AccordionDetails>
          {information.description}
        </AccordionDetails>
      </Accordion>
    </>
  )
}
