React Floater

View the demo

You can view and edit the code for each Floater here

Usage

Install.

npm install --save react-floater

Import it into your component:

import Floater from 'react-floater';

<Floater content="This is the Floater content">
    <span>click me</span>
</Floater>

And voíla!

Customization

You can use your own components to render the Floater with the prop component.
Check WithStyledComponents.js in the demo for an example.

If you use your own components as children it will receive an innerRef prop that you must set in your HTMLElement:
Stateless components don't accept refs...

const Button = ({ innerRef, ...rest }) => (
  <button ref={innerRef} {...rest} />
);

...
<Floater content="This is the Floater content">
    <Button>click me</Button>
</Floater>

This works transparently with styled-components (and possible other modules):

const Wrapper = styled.div`
  margin: 0 auto;
  max-width: 500px;
  line-height: 1.5;
`;

<Floater content="This is the Floater content">
    <Wrapper>click me</Wrapper>
</Floater>

Modes

Default
The wrapper will trigger the events and use itself as the Floater's target.

<Floater content="This is the Floater content">
    <span>click me</span>
</Floater>

Proxy
The wrapper will trigger the events but the Floater will use the target prop to position itself.

<div className="App">
    <img src="some-path" />

    <Floater
      content="This is the Floater content"
      target=".App img"
    >
        <span>click me</span>
    </Floater>
</div>

Beacon
The same as the proxy mode but the wrapper will be positioned relative to the target.

<div className="App">
    <img src="https://upload.wikimedia.org/wikipedia/commons/2/2d/Google-favicon-2015.png" width="100" className="my-super-image" />

    <Floater
        content="This is the Floater content"
        target=".my-super-image"
        wrapperOptions={{
            offset: -22,
            placement: 'top',
            position: true,
        }}
    >
    <span style={{ color: '#f04', fontSize: 34 }}>◉</span>
    </Floater>
</div>

Controlled
When you set a boolean to the open prop it will enter the controlled mode and it will not respond to events.
In this mode you don't even need to have children

<div className="App">
    <img src="some-path" />
    <Floater
        content="This is the Floater content"
        open={true}
        target=".App img"
    />
</div>
