从react-select中选择后如何持久保存搜索数据

Question

我在项目中使用react-select，因此我在选择一个值时尝试保留搜索数据。实际上，当我在“下拉列表”中搜索并选择一个值时，搜索数据已丢失。我要保留搜索数据。例如，当我选择F-10时，我在搜索F-1 to F-10的地方有一个下拉菜单，而当我选择F-6时，我的下拉菜单中的 import React from 'react'; import Select from 'react-select'; const areas = [ { label: "Newyork", value: newyork }, { label: "F-1", value: f1 }, { label: "F-2", value: f2 }, { label: "F-3", value: f3 }, { label: "F-4", value: f4 }, { label: "F-5", value: f5 }, { label: "F-6", value: f6 }, { label: "F-7", value: f7 }, { label: "F-8", value: f8 }, { label: "F-9", value: f9 }, { label: "F-10", value: f10 }, ]; const App = () => ( <div className="app"> <div className="container"> <Select options={areas} /> </div> </div> ); 则丢失了我的搜索数据。您能帮我如何保存我的搜索数据。

谢谢
