如何通过语义 UI 反应打开多个手风琴？

Question

我正在尝试使用包含多个条目的语义 UI 手风琴，并允许同时打开多个条目；每个条目都有一个标题部分，其中包含一个附加弹出窗口的图标，以及一个包含文本区域的内容区域。

我希望能够同时打开两个手风琴，这显然是exclusive={false}在制作手风琴元素时使用 prop 支持的，如文档中所述

但该示例看起来使用的是内容为字符串的对象数组，而不是其他 React/html/jsx 元素（在我的例子中，它是语义 ui 图标、弹出窗口和文本区域）。该对象数组被传递到手风琴的panel道具中。

而且我不熟悉语义 ui 反应手风琴需要什么才能正确运行并跟踪索引和其他内容，我不确定还需要配置什么，或者语义 ui 组件是否可以这样做。

我基本上复制了这个示例，并使用活动索引和 onclick 处理程序，该处理程序在组件反应状态下切换活动索引。

这是手风琴和 onclick 处理程序以及反应应用程序状态的片段：

class FileUpload extends Component {

 // other stuff omitted 

  constructor(props) {
    super(props);

    this.state = {
      activeAccordionIndex: -1
    };

  handleAccordionClick = (e, titleProps) => {
     const { index } = titleProps;
     const { activeAccordionIndex } = this.state;
     const newIndex = activeAccordionIndex === index ? -1 : index;

     this.setState({
       activeAccordionIndex: newIndex
     })
   }

 // I'm using a small helper function to create the accordion and invoke it in 
 // the render method, just one item for brevity; the other entries are pretty 
 // much the same

getAccordionInputs() {

     const { activeAccordionIndex } = this.state;

     let accordionContent = (
      <Accordion fluid exclusive={false}>
         <Accordion.Title
           className="file-upload-ordinal-accord-title"
           active={activeAccordionIndex === 0}
           index={0}
           onClick={this.handleAccordionClick}
          >
           <Icon name='dropdown' />
           Enter Ordinal Features
           <Popup
             on="click"
             position="right center"
             header="Ordinal Features Help"
             content={
               <div className="content">
                 <p>Ordinal Features help description</p>
               </div>
             }
             trigger={
               <Icon
                 className="file-upload-ordinal-help-icon"
                 inverted
                 size="large"
                 color="orange"
                 name="info circle"
               />
             }
           />
         </Accordion.Title>
         <Accordion.Content
            active={activeAccordionIndex === 0}
          >
           <textarea
             className="file-upload-ordinal-text-area"
             id="ordinal_features_text_area_input"
             label="Ordinal Features"
             placeholder={"{\"ord_feat_1\": [\"MALE\", \"FEMALE\"], \"ord_feat_2\": [\"FIRST\", \"SECOND\", \"THIRD\"]}"}
             onChange={this.handleOrdinalFeatures}
           />
         </Accordion.Content>
       </Accordion>
     )
     return accordionContent;
   }

  }

我不知道如何设置它以允许同时打开多个手风琴，其中内容不是字符串。这对于语义 ui 手风琴来说可能吗？或者我是否需要找到替代解决方案和/或手工制作具有所需行为的部件？

您可以更改索引逻辑，这样就不必在您的状态中设置活动索引，而是将索引添加到数组中，并检查它是否存在于数组中以及是否显示手风琴

这是一个例子：

export default class AccordionExampleStandard extends Component {
  state = { activeIndexs: [] };

  handleClick = (e, titleProps) => {
    const { index } = titleProps;
    const { activeIndexs } = this.state;
    const newIndex = activeIndexs;

    const currentIndexPosition = activeIndexs.indexOf(index);
    if (currentIndexPosition > -1) {
      newIndex.splice(currentIndexPosition, 1);
    } else {
      newIndex.push(index);
    }

    this.setState({ activeIndexs: newIndex });
  };

  render() {
    const { activeIndexs } = this.state;

    return (
      <Accordion>
        <Accordion.Title
          active={activeIndexs.includes(0)}
          index={0}
          onClick={this.handleClick}
        >
          <Icon name="dropdown" />
          What is a dog?
        </Accordion.Title>
        <Accordion.Content active={activeIndexs.includes(0)}>
          <p>
            A dog is a type of domesticated animal. Known for its loyalty and
            faithfulness, it can be found as a welcome guest in many households
            across the world.
          </p>
        </Accordion.Content>

        <Accordion.Title
          active={activeIndexs.includes(1)}
          index={1}
          onClick={this.handleClick}
        >
          <Icon name="dropdown" />
          What kinds of dogs are there?
        </Accordion.Title>
        <Accordion.Content active={activeIndexs.includes(1)}>
          <p>
            There are many breeds of dogs. Each breed varies in size and
            temperament. Owners often select a breed of dog that they find to be
            compatible with their own lifestyle and desires from a companion.

        <Accordion.Title
          active={activeIndexs.includes(2)}

          onClick={this.handleClick}
        >
          <Icon name="dropdown" />
          How do you acquire a dog?
        </Accordion.Title>
        <Accordion.Content active={activeIndexs.includes(2)}>
          <p>
            Three common ways for a prospective owner to acquire a dog is from
            pet shops, private owners, or shelters.
          </p>
          <p>
            A pet shop may be the most convenient way to buy a dog. Buying a dog
            from a private owner allows you to assess the pedigree and
            upbringing of your dog before choosing to take it home. Lastly,
            finding your dog from a shelter, helps give a good home to a dog who
            may not find one so readily.
