自定义控制字段不呈现 <select> 选项

Question

我正在努力 Field with Custom Control 严格按照官方教程实施。但是，尽管我的代码非常接近原始代码，但它呈现空 <select> 元素且 options 属性等于 [object Object],[object Object],[object Object] 而不是呈现填充了我的选项的下拉菜单：

const { useState } = React,
      { render } = ReactDOM,
      { Form } = semanticUIReact

const InputsBlock = () => {
  const selectOptions = [
          {key: 'option1', text: 'Option 1', value: 'Option 1'},
          {key: 'option2', text: 'Option 2', value: 'Option 2'},
          {key: 'option3', text: 'Option 3', value: 'Option 3'}
        ],
        fields = [
          {label: 'Param 1', key: 'param1', control: 'Input'},
          {label: 'Param 2', key: 'param2', control: 'Input'},
          {label: 'Param 3', key: 'param3', control: 'Select', options: selectOptions}
        ]

  return (
    <Form.Group widths="equal">
      {
        fields.map(({control,label,key,options}) => (
          <Form.Group inline>
            <Form.Field {...{key,control,label,...(control=='Select' && {options})}} />
          </Form.Group>
        ))
      }
    </Form.Group>
  )
}

const MyForm = () => {
  return (
    <Form>
      <InputsBlock />
    </Form>
  )  
}

render (
  <MyForm />,
  document.getElementById('root')
)

在您的字段数组中，控件不是字符串。相反，它应该是实际的语义-ui-react 组件。

将 "fields" 更改为以下 -

import { Form, Select, Input } from "semantic-ui-react";

fields = [
  { label: "Param 1", key: "param1", control: Input },
  { label: "Param 2", key: "param2", control: Input },
  {
    label: "Param 3",
    key: "param3",
    control: Select,
    options: selectOptions
  }
];

这是相同的工作代码 - https://codesandbox.io/s/optimistic-haslett-glvkf
