如何在 react-bootstrap 中打开多个手风琴选项卡？

Question

如果可能，我正在尝试打开多个手风琴。目前正在使用react-bootstrap图书馆。

以下是我的实现：

<Accordion>
  {data.rows.map((item, index) => {
    return (
      <Card
        style={{
          border: "none",
          marginTop: "1em",
          borderBottom: "1px solid #f1f1f1",
        }}
      >
        <Card.Header
          style={{ background: "transparent", padding: "0.75em 0" }}
        >
          <Row>
            <Col lg="10" sm xs="9" style={{ alignSelf: "center" }}>
              <p
                className="cardtitle"
                style={{ fontWeight: "600" }}
              >
                {item.title}
              </p>
            </Col>
            <Col style={{ textAlign: "right" }} xs sm>
              {" "}
              <ContextAwareToggle eventKey={index}>
                +
              </ContextAwareToggle>
            </Col>
          </Row>
        </Card.Header>
        <Accordion.Collapse eventKey={index}>
          <Card.Body>
            <p className="cardcontent">{item.content}</p>
          </Card.Body>
        </Accordion.Collapse>
      </Card>
    );
  })}{" "}
</Accordion>

...


function ContextAwareToggle({ children, eventKey, callback }) {
  const currentEventKey = useContext(Fifth);

  const decoratedOnClick = useAccordionToggle(
    eventKey,
    () => callback && callback(eventKey)
  );

  const isCurrentEventKey = currentEventKey === eventKey;
  console.log(currentEventKey);
  return (
    <button
      type="button"
      className="accordianButton"
      // style={{ backgroundColor: isCurrentEventKey ? "pink" : "lavender" }}
      style={{
        backgroundColor: "transparent",
        fontSize: "1.8em",
        fonWeight: "700",
        border: "transparent",
        color: "green",
      }}
      onClick={decoratedOnClick}
    >
      {isCurrentEventKey ? "-" : "+"}
    </button>
  );
}

以下是我获得代码参考的链接：https : //react-bootstrap.github.io/components/accordion/

另外，如果不是手风琴，请建议任何其他组件。一直试图在我的项目中创建一个常见问题模板。

谢谢

Accordion 组件旨在一次扩展一张卡片。要实现多个tab打开的效果，需要像这样使用多个Accordion：

import React from "react";
import { Accordion, Card, Button } from "react-bootstrap";

const tabs = [
  { id: 1, label: "Tab 1", description: "Content of Tab 1" },
  { id: 2, label: "Tab 2", description: "Content of Tab 2" },
  { id: 3, label: "Tab 3", description: "Content of Tab 3" }
];

export default function App() {
  return (
    <div className="App">
      {tabs.map(tab => (
        <Accordion key={tab.id} defaultActiveKey={tab.id}>
          <Card>
            <Card.Header>
              <Accordion.Toggle as={Button} variant="link" eventKey={tab.id}>
                {tab.label}
              </Accordion.Toggle>
            </Card.Header>
            <Accordion.Collapse eventKey={tab.id}>
              <Card.Body>{tab.description}</Card.Body>
            </Accordion.Collapse>
          </Card>
        </Accordion>
      ))}
    </div>
  );
}

更新：

现在可以在打开另一个选项卡时保持手风琴选项卡打开。这可以使用以下属性来实现alwaysOpen：

               <Accordion alwaysOpen>
                    <Accordion.Item eventKey="1">
                        <Accordion.Header>
                            Title
                        </Accordion.Header>
                        <Accordion.Body>
                             Test Body
                        </Accordion.Body>
                    </Accordion.Item>
                    <Accordion.Item eventKey="2">
                        <Accordion.Header>
                            Title
                        </Accordion.Header>
                        <Accordion.Body>
                             Test Body
                        </Accordion.Body>
                    </Accordion.Item>
                </Accordion>
