Component demos
Import
import Popper from '@mui/material/Popper';
// or
import { Popper } from '@mui/material';
Props of the native component are also available.
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.
Type:HTML element
| object
| func
The component used for the root node. Either a string to use a HTML element or a component.
Type:elementType
The components used for each slot inside the Popper. Either a string to use a HTML element or a component.
Type:{ Root?: elementType }
Default:{}
The props used for each slot inside the Popper.
Type:{ root?: func
| object }
Default:{}
An HTML element or function that returns one. The container
will have the portal children appended to it.
You can also provide a callback, which is called in a React layout effect. This lets you set the container from a ref, and also makes server-side rendering possible.
By default, it uses the body of the top-level document object, so it's simply document.body
most of the time.
Type:HTML element
| func
The children
will be under the DOM hierarchy of the parent component.
Type:bool
Default:false
Always 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.
Type:bool
Default:false
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.
