    npm version npm downloads Build Status

    Struggling with modals, lightboxes or loading bars in React? React-portal creates a new top-level React tree and injects its child into it. That's necessary for proper styling (especially positioning).


    • transports its child into a new React component and appends it to the document.body or a custom container (creates a new independent React tree)
    • can be opened by the prop isOpen
    • can be opened after a click on an element that you pass through the prop openByClickOn (and then it takes care of the open/close state)
    • doesn't leave any mess in DOM after closing
    • provides its child with this.props.closePortal callback
    • provides close on ESC and close on outside mouse click out of the box
    • supports absolute positioned components (great for tooltips)
    • no dependencies
    • fully covered by tests


    Try or

    git clone
    cd react-portal
    npm install
    npm run build:examples
    open examples/index.html


    npm install react react-dom react-portal --save


    import React from 'react';
    import ReactDOM from 'react-dom';
    import Portal from 'react-portal';
    export default class App extends React.Component {
      render() {
        const button1 = <button>Open portal with pseudo modal</button>;
        return (
          <Portal closeOnEsc closeOnOutsideClick openByClickOn={button1}>
              <h2>Pseudo Modal</h2>
              <p>This react component is appended to the document body.</p>
    export class PseudoModal extends React.Component {
      render() {
        return (
            <p><button onClick={this.props.closePortal}>Close this</button></p>
    ReactDOM.render(<App />, document.getElementById('react-body'));

    Documentation - props

    Always required

    children : ReactElement

    The portal expects one child (<Portal><Child ... /></Portal>) that will be ported.

    One of these two required

    isOpen : bool

    The V3 version uses isOpened. Renaming to isOpen is going to be released soon with the V4.

    If true, the portal is open. If false, the portal is closed. It's up to you to take care of the closing (aka taking care of the state). Don't use this prop if you want to make your life easier. Use openByClickOn instead!

    openByClickOn : ReactElement

    The second way how to open the portal. This element will be rendered by the portal immediately with onClick handler that triggers portal opening. How to close the portal then? The portal provides its ported child with a callback this.props.closePortal. Or you can use built-in portal closing methods (closeOnEsc, ... more below). Notice that you don't have to deal with the open/close state (like when using the isOpen prop).


    closeOnEsc: bool

    If true, the portal can be closed by the key ESC.

    closeOnOutsideClick: bool

    If true, the portal can be closed by the outside mouse click.

    onOpen: func(DOMNode)

    This callback is called when the portal is opened and rendered (useful for animating the DOMNode).

    beforeClose: func(DOMNode, removeFromDOM)

    This callback is called when the closing event is triggered but it prevents normal removal from the DOM. So, you can do some DOMNode animation first and then call removeFromDOM() that removes the portal from DOM.

    onClose: func

    This callback is called when the portal closes and after beforeClose.

    onUpdate: func

    This callback is called when the portal is (re)rendered.

    target: string

    Pass to render popup in a custom container instead of document.body. The container should be found by data attribute [data-portaltarget=${}]. There's also a helper component PortalTarget which creates an element with data-portaltarget={}:

    import React from 'react';
    import Portal, {PortalTarget} from 'react-portal';
    function App() {
      return (
            <PortalTarget name="target-id" />
            // renders inside PortalTarget
            <Popup target="target-id" />

    Tips & Tricks

    • Does your modal have a fullscreen overlay and the closeOnOutsideClick doesn't work? There is a simple solution.
    • Does your inner inner component <LevelTwo />
        <LevelTwo />

    also need an access to this.props.closePortal()? You can't just use {this.props.children} in render method of <LevelOne> component. You have to clone it instead:

      {closePortal: this.props.closePortal}

    Open modal programmatically

    Sometimes you need to open your portal (e.g. modal) automatically. There is no button to click on. No problem, because the portal has the isOpen prop, so you can just set it to true or false. However, then it's completely up to you to take care about the portal closing (ESC, outside click, no this.props.closePortal callback...).

    However, there is a nice trick how to make this happen even without isOpen:

    <Portal ref="myPortal">
      <PseudoModal title="My modal">
        Modal content
    // opens the portal, yay!
