reactjs - Material UI Drawer 组件中如何包含主组件的宽度？

问题描述

我正在尝试在 Material UI 中使用抽屉。

我希望主 div 的宽度在菜单抽屉使用其空间后占用视口中剩余的任何可用空间。

这是我的组件。我尝试将宽度设置为自动并在内容类上继承，但它不会改变任何东西。

我希望渲染主 div（抽屉中列表项的内容），以便在不水平滚动的情况下只占用尽可能多的可用空间。

解决方案

主要问题是 dash.jsx 中的以下内容：

  root: {
    display: 'flex',
  },

这在某种程度上破坏了Tabs其“可滚动选项卡”功能的机制，并导致Tabs占用显示其所有选项卡按钮而不是显示滚动按钮所需的宽度。display: 'flex'让管理内容宽度变得更容易（这样它会根据抽屉宽度自动调整），但用其他方式管理它并不难。

备选方案 1

在我修改过的沙箱版本中，为了修复display: 'flex'从根目录中删除的效果，我将 padding-left 添加到与抽屉宽度相同的内容中：

  content: {
    padding: theme.spacing(3),
    paddingLeft: theme.spacing(7) + 1,
    [theme.breakpoints.up("sm")]: {
      paddingLeft: theme.spacing(9) + 1
    }
  },
  contentDrawerOpen: {
    paddingLeft: drawerWidth
  },
...
<main className={clsx(classes.content, {[classes.contentDrawerOpen]: open})}>

编辑材料选项卡滚动

备选方案 2

另一种选择是离开display: 'flex'，但max-width在内容上适当地指定。

  content: {
    padding: theme.spacing(3),
    maxWidth: `calc(100vw - ${theme.spacing(7) + 1}px)`,
    [theme.breakpoints.up("sm")]: {
      maxWidth: `calc(100vw - ${theme.spacing(9) + 1}px)`
    }
  },
  contentDrawerOpen: {
    maxWidth: `calc(100vw - ${drawerWidth}px)`
  },

编辑材料选项卡滚动

备选方案 3（受 Ahmed Mokhtar 的回答启发）

将元素添加overflow: "auto"到content类中似乎也足够了：<main>

  content: {
    padding: theme.spacing(3),
    overflow: "auto"
  },

编辑材料选项卡滚动

最后一种选择绝对是最简单的。
