bpk-component-popover

Backpack popover component.

Installation

npm install bpk-component-popover --save-dev

Usage

import React, { Component } from 'react';
import BpkButton from 'bpk-component-button';
import BpkPopover from 'bpk-component-popover';
import BpkText from 'bpk-component-text';

class App extends Component {
  constructor() {
    super();

    this.ref = React.createRef();
    this.state = {
      isOpen: false,
    };

  }

  openPopover = () => {
    this.setState({
      isOpen: true,
    });
  }

  closePopover = () => {
    this.setState({
      isOpen: false,
    });
  }

  const target = (
    <div ref={this.ref} className={'my-popover-target'}>
      <BpkButton
        onClick={this.openPopover}>
          Open
      </BpkButton>
    </div>
  )

  render() {
    return (
      <div id="popover-container">
        <BpkPopover
          id="my-popover"
          target={target}
          onClose={this.closePopover}
          isOpen={this.state.isOpen}
          label="My popover"
          closeButtonText="Close"
          renderTarget={() =>
            document.getElementById('popover-container')
          }
          closeButtonProps={{
            tabIndex: 0,
          }}
        >
          <BpkText>My popover content</BpkText>
        </BpkPopover>
      </div>
    );
  }
}

Theming: In order to theme the modal, a renderTarget needs to be supplied as a function which returns a DOM node in the scope of a BpkThemeProvider.

Props

Property	PropType	Required	Default Value
children	node	true	-
closeButtonText	string	true	-
id	string	true	-
isOpen	bool	true	-
label	string	true	-
onClose	func	true	-
target	element or func	true	-
closeButtonIcon	bool	false	true
closeButtonProps	object	false	null

popperModifiers	arrayOf(object)	false	null
portalClassName	string	false	null
portalStyle	object	false	null
renderTarget	func	false	null

In order to attach the popover to a regular DOM element, provide a function which returns it to target:

<BpkPopover
  id="my-popover"
  target={() => document.getElementById('mydiv')}
  onClose={this.closePopover}
  isOpen={this.state.isOpen}
  label="My popover"
  closeButtonText="Close"
>
  <BpkText>My popover content</BpkText>
</BpkPopover>

Prop Details

onClose

const onClose = (event, {
  source: <string>, // One of `DOCUMENT_CLICK`, `CLOSE_BUTTON`, `CLOSE_LINK`, `ESCAPE`
}) => {
  ...
}

popperModifiers

Please refer to the documentation for the underlying positioning library "Popper.js". You can achieve various behaviours such as allowing the popover to overflow the viewport etc.

target

target can be a DOM element with a ref attached to it or a function that returns a DOM element.
