如何定制材料-ui手风琴组件的行为/风格？

Question

我有一个div容器(灰色)，它有一个手风琴组件，只有一个AccordionSummary组件。另一个(蓝色)在那个下面。一切看起来都很好(图1)。当我展开手风琴时：

• 它显示了AccordionDetails组件好的
• 自动调整灰色容器div的大小好的
• 但还不够，所以蓝色div超出了容器坏的(pic #2)

。

假设这是一个标准的手风琴组件行为。但你们中有谁遇到过这样的问题吗?你们是如何处理的？

Answer 1

使用挠曲盒和一般填充的根元素和边缘顶部的蓝色元素。

我认为您的问题是将绝对高度设置为像300 an这样的灰色元素，这使得问题使用了高度：“自动”和一般填充。

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

const useStyles = makeStyles((theme) => ({
  root: {
    display: "flex",
    flexDirection: "column",
    alignItems: "center",
    width: "100%",
    backgroundColor: "#eee",
    padding: 20,
  },
  heading: {
    fontSize: theme.typography.pxToRem(15),
    fontWeight: theme.typography.fontWeightRegular
  },
  rectangle: {
    width: "80%",
    height: 200,
    backgroundColor: "blue",
    marginTop:20
  }
}));

export default function App() {
  const classes = useStyles();

  return (
    <div className={classes.root}>
      <Accordion>
        <AccordionSummary
          expandIcon={<ExpandMoreIcon />}
          aria-controls="panel1a-content"
          id="panel1a-header"
        >
          <Typography className={classes.heading}>Accordion 1</Typography>
        </AccordionSummary>
        <AccordionDetails>
          <Typography>
            Lorem ipsum dolor sit amet, consectetur adipiscing elit. Suspendisse
            malesuada lacus ex, sit amet blandit leo lobortis eget.
          </Typography>
        </AccordionDetails>
      </Accordion>
      <div className={classes.rectangle} />
    </div>
  );
}

Answer 2

import Accordion from '@mui/material/Accordion';
import AccordionDetails from '@mui/material/AccordionDetails';
import AccordionSummary from '@mui/material/AccordionSummary';
import { styled } from '@mui/material/styles';

const CustomAccordion = styled(Accordion)(({ theme }) => {
  return {
    boxShadow: 'none', // this styles directly apply to accordion
    border: `1px solid gray`,
    '.MuiAccordionDetails-root': {},
    '.MuiAccordionSummary-root': {}, // this apply to Summary
  };
});

现在你可以用手风琴代替手风琴了
