# Popover

<p class="description">A Popover can be used to display some content on top of another.</p>

Things to know when using the `Popover` component:

- The component is built on top of the [`Modal`](/components/modal/) component.
- The scroll and click away are blocked unlike with the [`Popper`](/components/popper/) component.

## Simple Popover

## Anchor playground

Use the radio buttons to adjust the `anchorOrigin` and `transformOrigin` positions. You can also set the `anchorReference` to `anchorPosition` or `anchorEl`. When it is `anchorPosition`, the component will, instead of `anchorEl`, refer to the `anchorPosition` prop which you can adjust to set the position of the popover.

## Mouse over interaction

We demonstrate how to use the `Popover` component to implement a popover behavior based on the mouse over event.

For more advanced use cases you might be able to take advantage of:

### PopupState helper

There is a 3rd party package [`material-ui-popup-state`](https://github.com/jcoreio/material-ui-popup-state) that takes care of popover state for you in most cases.
