【问题描述】：

我正在玩 Material UI 抽屉组件，我希望抽屉位于应用栏下方，我想在其中切换汉堡图标的 onclick 以打开和关闭，当我单击汉堡图标时，它应该打开下面的抽屉然后再次点击它，它也应该关闭，我不希望汉堡图标移动它，它应该在一个地方是静态的。它不应该移动，只有抽屉应该打开和移动。我怎么能实现它在材质ui中 https://codesandbox.io/s/material-demo-forked-ehs05?file=/demo.js:0-6433

【参考方案1】：

我希望抽屉在应用栏下方

要将Drawer 放在AppBar 下方，请在AppBar 样式中添加以下行：

appBar: 
  zIndex: theme.zIndex.drawer + 1, // add this line to increate appBar z-index
,

它应该在一个地方是静止的。它不应该移动

如果您不想在打开Drawer 时移动AppBar，请删除appBarShift 样式。变化：

<AppBar
  position="fixed"
  className=clsx(classes.appBar, 
    [classes.appBarShift]: open,
  )
>

收件人：

<AppBar
  position="fixed"
  className=classes.appBar
>

我不希望汉堡图标在点击时移动

同样，在打开Drawer 时删除使IconButton 隐藏的样式

<IconButton className=classes.menuButton ...props />

当我点击汉堡图标时，它应该打开下面的抽屉，然后再次点击它也应该关闭

将handleDrawerOpen 替换为切换Drawer 的处理程序

const handleToggleDrawer = () => 
  setOpen((o) => !o);
;

<IconButton
  color="inherit"
  aria-label="open drawer"
  onClick=handleToggleDrawer
  edge="start"
  className=classes.menuButton
>
  <MenuIcon />
</IconButton>
