    npm version npm downloads Dependency Status JavaScript Style Guide code style: prettier

    React wrapper around PopperJS.

    Install

    npm install react-popper --save or yarn add react-popper

    <script src="https://unpkg.com/react-popper/dist/react-popper.js"></script>
    (UMD library exposed as `ReactPopper`)

    Usage

    import { Manager, Target, Popper, Arrow } from 'react-popper'
     
    const PopperExample = () => (
      <Manager>
        <Target style={{ width: 120, height: 120, background: '#b4da55' }}>
          Target Box
        </Target>
        <Popper placement="left" className="popper">
          Left Content
          <Arrow className="popper__arrow"/>
        </Popper>
        <Popper placement="right" className="popper">
          Right Content
          <Arrow className="popper__arrow"/>
        </Popper>
      </Manager>
    )

    Usage with child function

    This is a useful way to interact with custom components. Just make sure you pass down the refs properly.

    import { Manager, Target, Popper, Arrow } from 'react-popper'
     
    const PopperExample = () => (
      <Manager>
        <Target>
          {({ targetProps }) => (
            <div {...targetProps}>
              Target Box
            </div>
          )}
        </Target>
        <Popper placement="left">
          {({ popperProps, restProps }) => (
            <div
              className="popper"
              {...popperProps}
            >
              Popper Content
              <Arrow>
                {({ arrowProps, restProps }) => (
                  <span
                    className="popper__arrow"
                    {...arrowProps}
                  />
                )}
              </Arrow>
            </div>
          )}
        </Popper>
      </Manager>
    )

    Usage without Manager

    It's generally easiest to let the Manager and Target components handle passing the target DOM element to the Popper component. However, you can pass a target Element or a referenceObject directly into Popper if you need to.

    Handling DOM Elements from React can be complicated. The Manager and Target components handle these complexities for you, so their use is strongly recommended when using DOM Elements.

    import { PureComonent } from 'react'
    import { Popper, Arrow } from 'react-popper'
     
    class StandaloneExample extends PureComponent {
      state = {
        isOpen: false,
      }
     
      handleClick() = () => {
        this.setState(prevState => ({
          isOpen: !prevState.isOpen
        }))
      }
     
      render() {
        return (
          <div>
            <div
              ref={(div) => this.target = div}
              style={{ width: 120, height: 120, background: '#b4da55' }}
              onClick={this.handleClick}
            >
              Click {this.state.isOpen ? 'to hide' : 'to show'} popper
            </div>
            {this.state.isOpen && (
              <Popper className="popper" target={this.target}>
                Popper Content
                <Arrow className="popper__arrow"/>
              </Popper>
            )}
          </div>
        )
      }
    }

    Shared Props

    Target, Popper, and Arrow all share the following props

    component: PropTypes.oneOfType([PropTypes.node, PropTypes.func])

    A valid DOM tag or custom component to render. If using a custom component, an innerRef prop will be passed down that must be attached to the child component ref.

    innerRef: PropTypes.func

    Use this prop to access the internal ref. Does not apply to the Manager component since we do not interact with its ref.

    Manager

    This is a special component that provides the Target component to the Popper component. Pass any props as you normally would here.

    tag: PropTypes.oneOfType([PropTypes.string, PropTypes.bool])

    A valid DOM tag to render. Allows rendering just children by passing false. Once React 16 is out, this prop will most likely go away since we will be able to return an array and all this currently does is subscribe Target and Popper.

    Target

    This is just a simple component that subscribes to PopperManager, so Popper can make use of it. Again, pass any props as you normally would here.

    Each Target must be wrapped in a Manager, and each Manager can wrap only one Target.

    children: PropTypes.oneOfType([PropTypes.node, PropTypes.func])

    A Target's child may be one of the following:

    • a React element[s]

    • a function accepting the following object (all props must be passed down in order for the PopperJS to work properly)

      {
        targetProps: {
          ref, // a function that accepts the target component as an argument
        },
        restProps, // any other props that came through the Target component
      }

    Popper

    Your popper that gets attached to the Target component.

    Each Popper must either be wrapped in a Manager, or passed a target prop directly. Each Manager can wrap multiple Popper components.

    placement: PropTypes.oneOf(Popper.placements)

    eventsEnabled: PropTypes.bool

    modifiers: PropTypes.object

    target: PropTypes.oneOfType([PropTypes.instanceOf(Element), Popper.referenceObject])

    Passes respective options to a new Popper instance. As for onCreate and onUpdate, these callbacks were intentionally left out in favor of using the component lifecycle methods. If you have a good use case for these please feel free to file and issue and I will consider adding them in.

    children: PropTypes.oneOfType([PropTypes.node, PropTypes.func])

    A Popper's child may be one of the following:

    • a React element[s]

    • a function accepting the following object (all props must be passed down in order for the PopperJS to work properly)

      {
        popperProps: {
          ref, // a function that accepts the popper component as an argument
          style, // the styles to apply to the popper element
          'data-placement', // the placement of the Popper
        },
        restProps, // any other props that came through the Popper component
      }

    Arrow

    Another component that subscribes to the Popper component as an arrow modifier. Must be a child of Popper.

    children: PropTypes.oneOfType([PropTypes.node, PropTypes.func])

    An Arrow's child may be one of the following:

    • a React element[s]

    • a function accepting the following object (all props must be passed down in order for the PopperJS to work properly)

      {
        arrowProps: {
          ref, // a function that accepts the arrow component as an argument
          style, // the styles to apply to the arrow element
        },
        restProps, // any other props that came through the Arrow component
      }
