Any other properties supplied will be spread to the root element ([Popover](/api/popover)).

## CSS API

You can override all the class names injected by Material-UI thanks to the `classes` property.
This property accepts the following keys:
- `paper`

Have a look at [overriding with classes](/customization/overrides#overriding-with-classes) section
and the [implementation of the component](https://github.com/mui-org/material-ui/tree/master/packages/material-ui/src/Menu/Menu.js)
for more detail.

If using the `overrides` key of the theme as documented
[here](/customization/themes#customizing-all-instances-of-a-component-type),
you need to use the following style sheet name: `MuiMenu`.

## Inheritance

The properties of the [Popover](/api/popover) component are also available.
You can take advantage of this behavior to [target nested components](/guides/api#spread).
