React tooltip-lite

A lightweight and responsive tooltip. Feel free to Post an issue if you're looking to support more use cases.

Getting started

1. Install with NPM

$ npm install react-tooltip-lite

2. Import into your react Component

import Tooltip from 'react-tooltip-lite';

3. Wrap any element with the Tooltip component to make it a target

<Tooltip content="Go to google">
    <a href="http://google.com"> edge</a>
</Tooltip>

Important note about contents

@wowanalyzer/react-tooltip-lite needs a single element to attach to. This element can be either:

1. React component (<Link> for example, or your custom components)
2. HTML elements like <div>

It cannot be a React.Fragment because then it won't have a target to attach to. In the same sense, it can't be a plain text or text mixed with other JSX, then it needs a wrapper element.

If you wish to put a tooltip on a custom React component, you need to make sure it spreads other properties and sets ref property on some element, like here:

class SomeComponent extends React.Component {
  render() {
    const { innerRef, ...others } = this.props;
    return (
      <div 
        ref={innerRef} 
        {...others}
      >
        Hello
      </div>
    );
  }
}

<Tooltip content="Hello">
  <SomeComponent />
</Tooltip>

innerRef needs to be specifically deconstructed from this.props and set as a ref parameter on some element, same with ...others (it contains the mouseover/toggle events for the tooltip).

Alternatively, you can wrap the component in <div> or <span> element.

Styling

By default you need to style react-tooltip-lite with CSS, this allows for psuedo elements and some cool border tricks, as well as using css/sass/less variables and such to keep your colors consistent. (Note: as of version 1.2.0 you can also pass the "useDefaultStyles" prop which will allow you to use react-tooltip-lite without a stylesheet.)

Since the tooltip's arrow is created using the css border rule (https://css-tricks.com/snippets/css/css-triangle/), you'll want to specify the border-color for the arrow to set it's color.

Here's an example stylesheet:

.react-tooltip-lite {
  background: #333;
  color: white;
}

.react-tooltip-lite-arrow {
  border-color: #333;
}

Props

You can pass in props to define tip direction, styling, etc. Content is the only required prop.

Name	Type	Description
content	node (text or html)	the contents of your hover target
direction	string	the tip direction, defaults to up. Possible values are "up", "down", "left", "right" with optional modifer for alignment of "start" and "end". e.g. "left-start" will attempt tooltip on left and align it with the start of the target. If alignment modifier is not specified the default behavior is to align "middle".
className	string	css class added to the rendered tooltip
background	string	background color for the tooltip contents and arrow
color	string	text color for the tooltip contents
padding	string	padding amount for the tooltip contents (defaults to '10px')
eventOn	string	full name of supported react event to show the tooltip, e.g.: 'onClick'
eventOff	string	full name of supported react event to hide the tooltip, e.g.: 'onClick'
eventToggle	string	full name of supported react event to toggle the tooltip, e.g.: 'onClick', default hover toggling is disabled when using this option
useHover	boolean	whether to use hover to show/hide the tip, defaults to true
useDefaultStyles	boolean	uses default colors for the tooltip, so you don't need to write any CSS for it
isOpen	boolean	forces open/close state from a prop, overrides hover or click state
tipContentHover	boolean	defines whether you should be able to hover over the tip contents for links and copying content, defaults to false.
hoverDelay	number	the number of milliseconds to determine hover intent, defaults to 0
arrow	boolean	Whether or not to have an arrow on the tooltip, defaults to true
arrowSize	number	Number in pixels of the size of the arrow, defaults to 10
distance	number	The distance from the tooltip to the target, defaults to 10px with an arrow and 3px without an arrow

Here's an example using more of the props:

<Tooltip
  content={(
      <div>
          <h4 className="tip-heading">An unordered list to demo some html content</h4>
          <ul className="tip-list">
              <li>One</li>
              <li>Two</li>
              <li>Three</li>
              <li>Four</li>
              <li>Five</li>
          </ul>
      </div>
  )}
  direction="right"
>
    <span>
        Target content for big html tip
    </span>
</Tooltip>
