我想通过单击一个按钮来展开/折叠所有内容。

使用reactstrap并使用容器（index.js）中创建的组件创建了一个新的CollapsiblePanel组件。

现在，我可以通过单击按钮来展开/折叠所有容器。

CollapsiblePanel.js

import React,{ useState,useEffect } from "react";
import { Collapse } from "reactstrap";

function CollapsiblePanel({ children,...props }) {
    const { title,collapse } = props;
    const [isCollapse,setIsCollapse] = useState(collapse);
    const [icon,setIcon] = useState("fa fa-chevron-down");
    const toggle = () => {
        setIsCollapse(!isCollapse);
        setIcon(state => {
            return state === "fa fa-chevron-down"
                ? "fa fa-chevron-right"
                : "fa fa-chevron-down";
        });
    };

    useEffect(() => {
        toggle();
    },[collapse]);

    return (
        <div classname="coll-panel">
            <button
                type="button"
                classname="coll-panel-btn btn-primary btn-block text-left"
                onClick={() => toggle()}
            >
                <i classname={icon} /> {title}
            </button>
            <Collapse classname="border text-left p-2" isOpen={isCollapse}>
                {children}
            </Collapse>
        </div>
    );
}

CollapsiblePanel.defaultProps = {
    children: "Add node as a child",title: "Collapsible Panel",collapse: true
};

export default CollapsiblePanel;

index.js

import React,{ useState } from "react";
import ReactDOM from "react-dom";
import CollapsiblePanel from "./component/CollapsiblePanel";

import "../node_modules/bootstrap/dist/css/bootstrap.min.css";
import "./styles.css";

function App() {
    const text =
        "Lorem ipsum dolor sit amet consectetur adipisicing elit.Nihil earum illo ipsa velit facilis provident qui eligendi,quia ut magnam tenetur. accusantium nisi quos delectus in necessitatibus ad. Ducimus,id!";
    const [collapse,setCollapse] = useState(true);
    const [title,setTitle] = useState("Expand All");
    const [icon,setIcon] = useState("fa fa-chevron-right");
    const collapseAll = () => {
        setCollapse(!collapse);
        setIcon(state => {
            return state === "fa fa-chevron-right"
                ? "fa fa-chevron-down"
                : "fa fa-chevron-right";
        });
        setTitle(state => {
            return state === "Expand All" ? "Collapse All" : "Expand All";
        });
    };
    return (
        <div classname="App container my-2">
            {/* Expand/Collapse All */}
            <button
                type="button"
                classname="btn-warning mt-4 mb-3 float-left"
                onClick={collapseAll}
            >
                <i classname={icon} /> {title}
            </button>
            <CollapsiblePanel title="Title 1" collapse={collapse}>
                <span>{text}</span>
            </CollapsiblePanel>
            <CollapsiblePanel title="Title 2" collapse={collapse}>
                <span>{text}</span>
            </CollapsiblePanel>
            <CollapsiblePanel title="Title 3" collapse={collapse}>
                <span>{text}</span>
            </CollapsiblePanel>
            <CollapsiblePanel title="Title 4" collapse={collapse}>
                <span>{text}</span>
            </CollapsiblePanel>
            <CollapsiblePanel title="Title 5" collapse={collapse}>
                <span>{text}</span>
            </CollapsiblePanel>
        </div>
    );
}

现在： 在单击全部展开/折叠按钮之前，如果单击了可折叠容器（在index.js中），然后单击“展开/折叠”按钮，则并非所有容器都在展开。

打开的门正在关闭，反之亦然。

预期：

尽管已显式打开/关闭容器。在单击“展开/折叠”时，我要全部展开/折叠。预先感谢。
