Javascript 如何实现多语义UI允许添加下拉列表'；在一个反应组分中的s

我有一个

React组件

我正在尝试使用多个

语义用户界面

下面是我的代码：

const options = [
  { key: '1', text: '1', value: '1' },
  { key: '2', text: '2', value: '2' },
  { key: '3', text: '3', value: '3' },
  { key: '4', text: '4', value: '4' },
  { key: '5', text: '5', value: '5' },
  { key: '6', text: '6', value: '6' },
  { key: '7', text: '7', value: '7' },
  { key: '8', text: '8', value: '8' },
  { key: '9', text: '9', value: '9' },
