How to open/close Accordion programmatically

[irhamputra]

Hi Author and the community,

I'm asking for a help about how to open/close the accordion programmatically? I've been searching in the docs and the issue there is no answer related to this topic.

Any ideas and workaround would be appreciated.
Thank you

All of our components can be "controlled" if you would like to open/close them programmatically.

const [value, setValue] = React.useState('one');

return () => (
  <div>
	{/* Something outside of Accordion that controls the open content */}
    <button onClick={() => setValue('two')}>Open two</button>

    <Accordion.Root type="single" value={value} onValueChange={setValue}>
      <Accordion.Item value="one">
        <Accordion.Header>
          <Accordion.Trigger>One</Accordion.Trigger>
        </Accordion.Header>
        <Accordion.Content>
          Content for one
        <Accordion.Content>
      </Accordion.Item>
      <Accordion.Item value="two">
        <Accordion.Header>
          <Accordion.Trigger>Two</Accordion.Trigger>
        </Accordion.Header>
        <Accordion.Content>
          Content for two
        <Accordion.Content>
      </Accordion.Item>
    </Accordion.Root>
  </div>

Copy and paste this simple example into the docs 📝 ❓ @jjenzz Respectfully, there's nothing major here, and yet it just didn't occur to me to do this until I took 5 seconds to look at the code!

[obrunofontana]

its work. thank you!!

[TomasHubelbauer]

Anyone else able to make this work to close the opened single AccordionItem? When I set the state driving value to undefined, the currently opened item just remains opened. :/

[manavm1990]

Maybe 🤔 you can share some code? You may not need even need any State if it's "single".

[jjenzz]

@TomasHubelbauer are you looking for the collapsible prop by any chance?

[KarthikRaju391]

Is there a way to know the open or closed state of an accordion?

[joaom00]

via css you can use the data-state="open | closed" attribute to style and via js controlling the component like #824 (comment)

[emilioaray-dev]

If possible, here's an example evaluating the [data-state] value and using useRef in case you need to map your component.

import React, { useEffect, useRef, useState } from "react";
import { Accordion, AccordionTrigger, AccordionContent, AccordionItem } from "@radix-ui/react-accordion";

const YourComponent = () => {
  const [isOpenAccordion, setIsOpenAccordion] = useState(null);
  const [isClicked, setIsClicked] = useState<boolean | null>(null);
  const accordionTriggerRef = useRef(null);

  useEffect(() => {
    if (accordionTriggerRef.current) {
      const accordionTriggerElement = accordionTriggerRef.current;
      const dataState = accordionTriggerElement.getAttribute("data-state");

      if (dataState === "closed") {
        setIsOpenAccordion(false);
        console.log("AccordionTrigger is closed.");
      }

      if (dataState === "open") {
        setIsOpenAccordion(true);
        console.log("AccordionTrigger is open.");
      }
    }
  }, [isClicked]);

  return (
    <>
      <div>
        <Accordion type="multiple">
          <AccordionItem ref={accordionTriggerRef} value="YourAccordion">
            <AccordionTrigger
              onClick={() => {
                setIsClicked(!isClicked);
              }}
            >
              {/* Your AccordionTrigger UI here */}
            </AccordionTrigger>
            <AccordionContent>
              {isOpenAccordion ? (
                // Content to display when the Accordion is open
                <p>Accordion Content (This content is shown only if the Accordion is open)</p>
              ) : null}
            </AccordionContent>
          </AccordionItem>
        </Accordion>
      </div>
    </>
  );
};

export default YourComponent;

I hope you find it useful. 👍

@emilioaray-dev i'm a bit late seeing this but as @joaom00 suggested, the controlled API is meant for this and it would make your code simpler (more declarative):

import React, { useEffect, useRef, useState } from "react";
import { Accordion, AccordionTrigger, AccordionContent, AccordionItem } from "@radix-ui/react-accordion";

const YourComponent = () => {
  const [values, setValues] = React.useState<string[]>([]);

  return (
    <>
      <div>
        <Accordion type="multiple" value={values} onValueChange={setValues}>
          <AccordionItem value="YourAccordion">
            <AccordionTrigger>
              {/* Your AccordionTrigger UI here */}
            </AccordionTrigger>
            <AccordionContent>
              {/* derive the `isOpen` state based on `values` */}
              {values.includes("YourAccordion") ? (
                // Content to display when the Accordion is open
                <p>Accordion Content (This content is shown only if the Accordion is open)</p>
              ) : null}
            </AccordionContent>
          </AccordionItem>
        </Accordion>
      </div>
    </>
  );
};

export default YourComponent;

@jjenzz how can i trigger from other component? suppose I will click a button which is not part of the accordion component.

update:
I solved it from Your first answer.

[sigmarsson]

Could anyone explain me what the purpose is of <AccordionTrigger> instead of <Accordion.Trigger> ?

[TobiasLueger]

Hey all,
I followed this conversation. How can I open all ans close all with two seperate Buttons. I tried something like that but it doesn't work.

import { Root as RDXAccordion } from "@radix-ui/react-accordion";
import clsx from "clsx";
import { Children, isValidElement, useEffect, useState } from "react";

import styles from "./Accordion.module.scss";
import { AccordionProps } from "./types.ts";

export function Accordion({
  children,
  className,
  type,
  dataTestId,
  openAll,
  ...props
}: AccordionProps) {
  const [openAccordionItems, setOpenAccordionItems] = useState<string[]>();

  const setOpenValues = (values: string[]) => {
    setOpenAccordionItems(values);
  };

  useEffect(() => {
    const convertAllAccordionItemValuesToStringArray = () => {
      const values: string[] = [];
      const getAllAccordionItemValues = (children: React.ReactNode) => {
        Children.forEach(children, (child) => {
          if (isValidElement(child)) {
            console.log("Test", child);
            if ((child.type as any).displayName === "AccordionItem")
              return values.push((child as React.ReactElement).props.value);
            return getAllAccordionItemValues(
              (child as React.ReactElement).props.children
            );
          }
        });
      };
      getAllAccordionItemValues(children);
      return values;
    };

    if (openAll) {
      setOpenAccordionItems(convertAllAccordionItemValuesToStringArray());
    } else {
      setOpenAccordionItems([]);
    }
  }, [children, openAll]);

  return (
    <RDXAccordion
      type={type || "multiple"}
      className={clsx(className, styles.accordion)}
      data-testid={dataTestId || "accordion"}
      value={openAccordionItems} //there has to be a array of AccordionItem Values to open all accordions
      onValueChange={setOpenValues}
      {...props}
    >
      {children}
    </RDXAccordion>
  );
}`

I hope someone have an Idea 🔥 ❤️
