Installation

npm install 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/standalone/react-tooltip.min.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

Check example: React-tooltip Test

Global	Specific	Type	Values	Description
place	data-place	String	top, right, bottom, left	placement
type	data-type	String	success, warning, error, info, light	theme
effect	data-effect	String	float, solid	behaviour of tooltip
event	data-event	String	e.g. click	custom event to trigger tooltip
eventOff	data-event-off	String	e.g. click	custom event to hide tooltip (only makes effect after setting event attribute)
globalEventOff		String	e.g. click	global event to hide tooltip (global only)
isCapture	data-iscapture	Bool	true, false	when set to true, custom event's propagation mode will be capture
offset	data-offset	Object	top, right, bottom, left	data-offset="{'top': 10, 'left': 10}" for specific and offset={{top: 10, left: 10}} for global
multiline	data-multiline	Bool	true, false	support <br>, <br /> to make multiline
className	data-class	String		extra custom class, can use !important to overwrite react-tooltip's default class
html	data-html	Bool	true, false	<p data-tip="<p>HTML tooltip</p>" data-html={true}></p> or <ReactTooltip html={true} />, but see Security Note below.
delayHide	data-delay-hide	Number		<p data-tip="tooltip" data-delay-hide='1000'></p> or <ReactTooltip delayHide={1000} />
delayShow	data-delay-show	Number		<p data-tip="tooltip" data-delay-show='1000'></p> or <ReactTooltip delayShow={1000} />
delayUpdate	data-delay-update	Number		<p data-tip="tooltip" data-delay-update='1000'></p> or <ReactTooltip delayUpdate={1000} /> Sets a delay in calling getContent if the tooltip is already shown and you mouse over another target
insecure	null	Bool	true, false	Whether to inject the style header into the page dynamically (violates CSP style-src but is a convenient default)
border	data-border	Bool	true, false	Add one pixel white border
getContent	null	Func or Array	(dataTip) => {}, [(dataTip) => {}, Interval]	Generate the tip content dynamically
afterShow	null	Func	(evt) => {}	Function that will be called after tooltip show, with event that triggered show
afterHide	null	Func	(evt) => {}	Function that will be called after tooltip hide, with event that triggered hide
disable	data-tip-disable	Bool	true, false	Disable the tooltip behaviour, default is false
scrollHide	data-scroll-hide	Bool	true, false	Hide the tooltip when scrolling, default is true
resizeHide	null	Bool	true, false	Hide the tooltip when resizing the window, default is true
wrapper	null	String	div, span	Selecting the wrapper element of the react tooltip, default is div
clickable	null	Bool	true, false	Enables tooltip to respond to mouse (or touch) events, default is false

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-react. 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.

Using react component as tooltip

Check the example React-tooltip Test

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>
