## Installation

```sh
npm install react-tooltip
```

```sh
yarn add react-tooltip
```

## Usage

### Using NPM

1 . Require react-tooltip after installation

```js
import ReactTooltip from 'react-tooltip';
```

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

```jsx
Tooltip
```

3 . Include react-tooltip component

```jsx
<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 |
| :--------------- | :-------------------- | :------------ | :------------------------------------------------------------------------------------------------------------------------------------ | :-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |

| 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 ` `, ` ` 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 | `HTML tooltip" data-html={true}>` or `<ReactTooltip html={true} />`, but see [Security Note](#security-note) below. |
| delayHide | data-delay-hide | Number | | `` or `<ReactTooltip delayHide={1000} />` |
| delayShow | data-delay-show | Number | | `` or `<ReactTooltip delayShow={1000} />` |
| delayUpdate | data-delay-update | Number | | `` 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 |

| backgroundColor | data-background-color | String | e.g. yellow | Popup background color |
| borderColor | data-border-color | String | e.g. green | Popup border color - enabled by the `border` value |
| arrowColor | data-arrow-color | String | e.g. #fff | Popup arrow color - if not specified, will use the `backgroundColor` value |
| 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 |
| overridePosition | null | Func | ({left:number, top: number}, currentEvent, currentTarget, node, place, desiredPlace, effect, offset) => ({left: number, top: number}) | Function that will replace tooltip position with custom one |
| 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](https://www.npmjs.com/package/sanitize-html). We chose not to include sanitization after discovering it [increased our package size](https://github.com/wwayne/react-tooltip/issues/429) too much - we don't want to penalize people who don't use the `html` option.

#### 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 **id**s

## Static Methods

### ReactTooltip.hide(target)

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

```jsx
import ReactTooltip from 'react-tooltip'

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

### ReactTooltip.rebuild()

> Rebinding all tooltips

### ReactTooltip.show(target)

> Show specific tooltip manually, for example:

```jsx
import ReactTooltip from 'react-tooltip'

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

## Troubleshooting

### 1. Using tooltip within the modal (e.g. [react-modal](https://github.com/reactjs/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](https://github.com/wwayne/react-tooltip/issues/130). 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.

```jsx

<ReactTooltip id='test' getContent={() => { return null }}/>
```

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

```jsx

<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

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

```jsx

const dynamicList = (props) => {

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

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

```
