Popover 弹出框

使用弹出框组件，您可在另一个元素之上显示一些内容。

使用弹出框组件时，你需要了解的事项：

The component is built on top of the Modal component.
The scroll and click away are blocked unlike with the Popper component.

<Button aria-describedby={id} variant="contained" onClick={handleClick}>
  Open Popover
</Button>
<Popover
  id={id}
  open={open}
  anchorEl={anchorEl}
  onClose={handleClose}
  anchorOrigin={{
    vertical: 'bottom',
    horizontal: 'left',
  }}
>
  <Typography sx={{ p: 2 }}>The content of the Popover.</Typography>
</Popover>

<Button aria-describedby={id} variant="contained" onClick={handleClick}>
  Open Popover
</Button>
<Popover
  id={id}
  open={open}
  anchorEl={anchorEl}
  onClose={handleClose}
  anchorOrigin={{
    vertical: 'bottom',
    horizontal: 'left',
  }}
>
  <Typography sx={{ p: 2 }}>The content of the Popover.</Typography>
</Popover>

锚点（Anchor）测试

你可以使用单选按钮（radio buttons）调整 anchorOrigin 和 transformOrigin 的位置。您还可以将 anchorReference 设置为 anchorPosition 或 anchorEl。当设置为 anchorPosition 时，该组件将指向 anchorPosition 属性，用其可以调整设置弹出框的位置，而不是指向anchorEl。

<Popover 
  anchorOrigin={{
    vertical: 'top',
    horizontal: 'left',
  }}
  transformOrigin={{
    vertical: 'top',
    horizontal: 'left',
  }}
>
  The content of the Popover.
</Popover>

鼠标悬停的交互事件
