react-tooltip

What is react-tooltip?

The react-tooltip npm package is a versatile library for React that allows developers to easily add custom tooltips to their web applications. It provides a range of options for styling, positioning, and triggering tooltips, making it a convenient tool for enhancing user interface elements with additional information.

What are react-tooltip's main functionalities?

Simple Tooltips

This feature allows you to create simple tooltips with minimal configuration. By adding a 'data-tip' attribute to any React element and including the ReactTooltip component, a tooltip will appear on hover.

{"import React from 'react';\nimport ReactTooltip from 'react-tooltip';\n\nfunction App() {\n  return (\n    <div>\n      <p data-tip='hello world'>Hover over me to see the tooltip!</p>\n      <ReactTooltip />\n    </div>\n  );\n}\n\nexport default App;"}

Custom Styles

React-tooltip allows for custom styling of tooltips. You can specify the type (theme), effect, place, and even add custom classes for additional styling.

{"import React from 'react';\nimport ReactTooltip from 'react-tooltip';\n\nfunction App() {\n  return (\n    <div>\n      <p data-tip='Custom styles!' data-for='customStyle'>Hover over me!</p>\n      <ReactTooltip id='customStyle' type='dark' effect='solid' place='top' className='extraClass' />\n    </div>\n  );\n}\n\nexport default App;"}

Dynamic Content

Tooltips can display dynamic content that changes based on the application's state. This is useful for tooltips that need to update to reflect user interactions or other real-time data.

{"import React, { useState } from 'react';\nimport ReactTooltip from 'react-tooltip';\n\nfunction App() {\n  const [dynamicTip, setDynamicTip] = useState('Initial tooltip content');\n\n  return (\n    <div>\n      <p data-tip data-for='dynamicTip'>Hover over me for dynamic content!</p>\n      <ReactTooltip id='dynamicTip'>{dynamicTip}</ReactTooltip>\n      <button onClick={() => setDynamicTip('Updated tooltip content')}>Update Tooltip</button>\n    </div>\n  );\n}\n\nexport default App;"}

HTML Content

React-tooltip supports HTML content inside tooltips. This allows for more complex and styled content to be displayed within the tooltip.

{"import React from 'react';\nimport ReactTooltip from 'react-tooltip';\n\nfunction App() {\n  return (\n    <div>\n      <p data-tip data-for='htmlContent'>Hover over me for HTML content!</p>\n      <ReactTooltip id='htmlContent' dangerouslySetInnerHTML={{ __html: '<strong>HTML</strong> content' }} />\n    </div>\n  );\n}\n\nexport default App;"}

Other packages similar to react-tooltip

tippy.js

Tippy.js is a highly customizable tooltip and popover library powered by Popper.js. It offers a wide range of options and plugins for creating interactive tooltips and popovers. Compared to react-tooltip, Tippy.js provides more out-of-the-box animations and is not limited to React.

rc-tooltip

Rc-tooltip is a React component for tooltip functionality. It is part of the rc-components family and offers a simple API for creating and managing tooltips. While react-tooltip is more feature-rich and has a larger community, rc-tooltip is a good alternative for those already using other rc-components.

react-tippy

React-tippy is a React wrapper for Tippy.js, bringing its powerful tooltip capabilities to React applications. It combines the extensive features of Tippy.js with a React-friendly interface. React-tippy may be preferred by developers who want the advanced features of Tippy.js in a React-specific package.

Usage

Using NPM

1 . Require react-tooltip after installation

import ReactTooltip from 'react-tooltip';

2 . Add data-tip = "your placeholder" to your element

<p data-tip="hello world">Tooltip</p>

3 . Include react-tooltip component

<ReactTooltip />

Standalone

You can import node_modules/react-tooltip/dist/index.js into your page. Please make sure that you have already imported react and react-dom into your page.

Options

Notes:

• The tooltip sets type: dark place: top effect: float as default attributes. You don't have to add these options if you don't want to change the defaults
• The option you set on <ReactTooltip /> component will be implemented on every tooltip in a same page: <ReactTooltip effect="solid" />
• The option you set on a specific element, for example: <a data-type="warning"></a> will only affect this specific tooltip

Global	Specific	Type	Values	Description
place	data-place	String	"top", "right", "bottom", "left", or comma-separated e.g. "left,right"	placement - can specify a comma-separated list of preferences that will be attempted in order

Security Note

The html option allows a tooltip to directly display raw HTML. This is a security risk if any of that content is supplied by the user. Any user-supplied content must be sanitized, using a package like sanitize-html. We chose not to include sanitization after discovering it increased our package size too much - we don't want to penalize people who don't use the html option.

JSX Note

You can use React's renderToStaticMarkup-function to use JSX instead of HTML. You still need to set data-html={true}. Example:

import ReactDOMServer from 'react-dom/server';
[...]
<p data-html={true} data-tip={ReactDOMServer.renderToString(<div>I am <b>JSX</b> content</div>)}>
  Hover me
</p>

Note

1. data-tip is necessary, because <ReactTooltip /> finds the tooltip via this attribute
2. data-for corresponds to the id of <ReactTooltip />
3. When using react component as tooltip, you can have many <ReactTooltip /> in a page but they should have different ids

Static Methods

ReactTooltip.hide(target)

Hide the tooltip manually, the target is optional, if no target passed in, all existing tooltips will be hidden

import ReactTooltip from 'react-tooltip'

<p ref={ref => this.fooRef = ref} data-tip='tooltip'></p>
<button onClick={() => { ReactTooltip.hide(this.fooRef) }}></button>
<ReactTooltip />

ReactTooltip.rebuild()

Rebinding all tooltips

ReactTooltip.show(target)

Show specific tooltip manually, for example:

import ReactTooltip from 'react-tooltip'

<p ref={ref => this.fooRef = ref} data-tip='tooltip'></p>
<button onClick={() => { ReactTooltip.show(this.fooRef) }}></button>
<ReactTooltip />

Troubleshooting

1. Using tooltip within the modal (e.g. react-modal)

The component was designed to set <ReactTooltip /> once and then use tooltip everywhere, but a lot of people get stuck when using this component in a modal. You can read the discussion here. To solve this problem:

1. Place <ReactTooltip /> outside of the <Modal>
2. Use ReactTooltip.rebuild() when opening the modal
3. If your modal's z-index happens to be higher than the tooltip's, use the attribute className to custom your tooltip's z-index

I suggest always putting <ReactTooltip /> in the Highest level or smart component of Redux, so you might need these static method to control tooltip's behaviour in some situations

2. Hide tooltip when getContent returns undefined

When you set getContent={() => { return }} you will find the tooltip will display true. That's because React will set the value of data-* to be 'true' automatically if there is no value to be set. So you have to set data-tip='' in this situation.

<p data-tip='' data-for='test'></p>
<ReactTooltip id='test' getContent={() => { return null }}/>

Same for empty children, if you don't want show the tooltip when the children is empty

<p data-tip='' data-for='test'></p>
<ReactTooltip id='test'>{}</ReactTooltip>

3. Tooltip not binding to dynamic content

When you render <ReactTooltip> ahead of dynamic content, and are using data-for={id} attributes on new dynamic content, the tooltip will not register its event listener.

For example, you render a generic tooltip in the root of your app, then load a list of content async. Elements in the list use the data-for={id} attribute to bind the tooltip on hover. Since the tooltip has already scanned for data-tip these new elements will not trigger.

One workaround for this is to trigger ReactTooltip.rebuild() after the data load to scan for the attribute again, to allow event wireup.

Example

<app>
  <ReactTooltip id="foo" />
  <list />
</app>

const dynamicList = (props) => {

 useEffect(() => {
        ReactTooltip.rebuild();
    });

return(
  <list>
    {data.map((item)=> {
      <span data-for="foo">My late bound tooltip triggered data</span>
    });}
  </list>
);
};
