Popper API

API documentation for the React Popper component. Learn about the available props, and the CSS API.

Import

import Popper from '@material-ui/core/Popper';
// or
import { Popper } from '@material-ui/core';
You can learn about the difference by reading this guide on minimizing bundle size.

Poppers rely on the 3rd party library Popper.js for positioning.

Props

NameTypeDefaultDescription
anchorElHTML element
| object
| func
An HTML element, virtualElement, or a function that returns either. It's used to set the position of the popper. The return value will passed as the reference object of the Popper instance.
childrennode
| func
Popper render function or node.
containerHTML element
| func
An HTML element or function that returns one. The container will have the portal children appended to it.
By default, it uses the body of the top-level document object, so it's simply document.body most of the time.
disablePortalboolfalseThe children will be under the DOM hierarchy of the parent component.
keepMountedboolfalseAlways keep the children in the DOM. This prop can be useful in SEO situation or when you want to maximize the responsiveness of the Popper.

Popper.js is based on a "plugin-like" architecture, most of its features are fully encapsulated "modifiers".
A modifier is a function that is called each time Popper.js needs to compute the position of the popper. For this reason, modifiers should be very performant to avoid bottlenecks. To learn how to create a modifier, read the modifiers documentation.
open*boolfalseIf true, the component is shown.
