场景：我需要完成一个筛选的功能、请看下图：
UI框架：antd；组件 Select
问题：代码重复量比较多、多个筛选需要写多个Select组件 请问有没有更好的方案？
下图是我的部分代码截图；详细的代码在底部
import React from 'react'
import { Select } from 'antd';
import styles from './search.moudule.scss'
const { Option } = Select;
console.log(styles)
class Search extends React.Component {
constructor (props) {
super(props)
this.state = {
search:{
citys:"",
years:"",
grades:"",
subjects:"",
semesters:"",
states:"",
},
citys:[ // 城市list
{
key:1,
value:"北京"
},
{
key:2,
value:"上海"
}
],
years:[ // 年份list
{
key:1,
value:"2020"
},
{
key:2,
value:"2021"
}
],
grades:[ // 年级list
{
key:1,
value:"早教"
},
{
key:2,
value:"托班"
}
],
subjects:[ // 学科list
{
key:1,
value:"数学"
},
{
key:2,
value:"英语"
}
],
semesters:[ // 学期list
{
key:1,
value:"春季"
},
{
key:2,
value:"秋季"
}
],
states:[ // 状态list
{
key:1,
value:"未发布"
},
{
key:2,
value:"已开启"
}
]
}
this.handleChange = this.handleChange.bind(this)
}

export default Search
html5
然后通过遍历渲染
m -> v
