Installation

npm install react-tooltip

or

yarn add react-tooltip

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

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>
);
};
