首次单击 Accordion 传播后，如何禁用它？

Question

我有一个Accordion与TextField在AccordionSummary （材料-UI）点击它时，打开AccordionDetails但是，随着形式的休息，我不能从触发传播打开和关闭工作，如何停止在球场上多次点击第一次点击后的手风琴内容。 我不希望在AccountSummary第一次单击后新可见的表单内容消失。 我知道如何在第一次输入字段时禁用传播，但不知道如何只允许传播一次？

import React from "react";
import { Formik, Field, Form } from "formik";
import { TextField, Select } from "formik-material-ui";

const AccordionSummary = withStyles({
  root: {
    "&.Mui-focused": {
      backgroundColor: "inherit"
    }
  }
})(MuiAccordionSummary);

const AccordionDetails = withStyles({
  root: {
    paddingTop: 0
  }
})(MuiAccordionDetails);

export default function App() {

我可以在不造成巨大性能损失的情况下使其正常工作的唯一方法如下：

import Accordion from "@material-ui/core/Accordion";
import AccordionDetails from "@material-ui/core/AccordionDetails";
import AccordionSummary from "@material-ui/core/AccordionSummary";
import Typography from "@material-ui/core/Typography";
import ExpandMoreIcon from "@material-ui/icons/ExpandMore";
import React, { useState } from "react";

export default function ControlledAccordions() {
  const [expanded, setExpanded] = useState("");
  const handleChange = (panel) => () => {
    setExpanded(panel);
  };

  return (
    <div>
      <Accordion
        expanded={expanded === "panel1"}
        onChange={handleChange("panel1")}
      >
        <AccordionSummary expandIcon={<ExpandMoreIcon />}>
          <Typography>General settings</Typography>
          <Typography>I am an accordion</Typography>
        </AccordionSummary>
        <AccordionDetails>
          <Typography>
            Nulla facilisi. Phasellus sollicitudin nulla et quam mattis feugiat.
            Aliquam eget maximus est, id dignissim quam.
          </Typography>
        </AccordionDetails>
      </Accordion>
    </div>
  );
}
