How to import

import { Tooltip } from '@douyinfe/semi-ui';

Cautions

Tooltip needs to apply DOM event listeners to children. If the child element is a custom component, you need to ensure that it can pass properties to the underlying DOM element

At the same time, in order to calculate the positioning of the popup layer, it is necessary to obtain the real DOM elements of the children, so Tooltip supports the following types of children

Class Component, it is not mandatory to bind ref, but you need to ensure that props can be transparently transmitted to the real DOM node
Use the functional component wrapped by forwardRef to transparently transmit props and ref to the real DOM node in children

Real DOM nodes, such as span, div, p...

import React, { forwardRef } from 'react';
import { Tooltip, Space } from '@douyinfe/semi-ui';

const style={ border: '2px solid var(--semi-color-border)', paddingLeft: 4, paddingRight: 4, borderRadius: 4 };

// Spread the props to the underlying DOM element. binding ref
const FCChildren = forwardRef((props, ref) => {
return (<span {...props} ref={ref} style={style}>Functional Component</span>);
});

// Spread the props to the underlying DOM element.
class MyComponent extends React.Component {
render() {
    return (<span {...this.props} style={style}>ClassComponent</span>);
}
};

function Demo() {
return (
    <Space>
        <Tooltip content={'semi design'}>
            <FCChildren />
        </Tooltip>
        <Tooltip content={'semi design'}>
            <MyComponent />
        </Tooltip>
        <Tooltip content={'semi design'}>
            <span style={style}>DOM</span>
        </Tooltip>
    </Space>
);
}
render(Demo);

Position

The direction and alignment position of the popup layer can be configured through position. For detailed optional values of position, please refer to the API document below

When configured as topLeft, it pops up, and the popup layer is left-aligned with the children (when arrowPointAtCenter=false) . When configured as topRight, it pops up, and the popup layer is right-aligned with the children (when arrowPointAtCenter=false) . Same for other directions

import React from 'react';
import { Tooltip, Tag } from '@douyinfe/semi-ui';

function Demo() {
    const tops = [
        ['topLeft', 'TL'],
        ['top', 'Top'],
        ['topRight', 'TR'],
    ];
    const lefts = [
        ['leftTop', 'LT'],
        ['left', 'Left'],
        ['leftBottom', 'LB'],
    ];
    const rights = [
        ['rightTop', 'RT'],
        ['right', 'Right'],
        ['rightBottom', 'RB'],
    ];
    const bottoms = [
        ['bottomLeft', 'BL'],
        ['bottom', 'Bottom'],
        ['bottomRight', 'BR'],
    ];

                ))}
            </div>
        </div>
    );
}

Arrow Point at Center

By default arrowPointAtCenter=true, the small triangle always points to the center of the children element.
You can set it to false and the little triangle will no longer keep pointing to the center of the element. The popover is aligned to the edges of the children

import React from 'react';
import { Tooltip, Button } from '@douyinfe/semi-ui';

function Demo() {
    return (
        <>
            <div>
                <Tooltip
                    position='topLeft'
                    content='semi design tooltip'>
                    <Button type='secondary' style={{ marginRight: 8 }}>Arrow Point at Center</Button>
                </Tooltip>
            </div>

            <div style={{ marginTop: 20 }}>
                <Tooltip
                    content='semi design tooltip'
                    arrowPointAtCenter={false}
                    position='topLeft'
                >
                    <Button type='secondary' style={{ marginRight: 8, width: 120 }}>Edge align</Button>
                </Tooltip>
            </div>
        </>
    );
};

Trigger Timing

Configure the timing of the trigger display, the default is hover, optional hover / focus / click / custom .

When set to custom, it needs to be used in conjunction with the visibleattribute, at which point the display is completely controlled

import React, { useState } from 'react';
import { Tooltip, Button, ButtonGroup, Input } from '@douyinfe/semi-ui';

function Demo() {
const [visible, setVisible] = useState(false);
// Container needs to set position: relative
const getPopupContainer = () => document.querySelector('#tooltip-container');

return (
    <div style={{ width: '100%', height: '100%', overflow: 'hidden', position: 'relative' }} id="tooltip-container">
        <div style={{ width: '150%', height: '150%', paddingLeft: 50, paddingTop: 50 }}>
            <Tooltip content={'hi bytedance'} getPopupContainer={getPopupContainer}>
                <Button style={{ marginBottom: 20 }}>Hover to show</Button>
            </Tooltip>
            <br />
            <Tooltip content={'hi bytedance'} trigger="click" getPopupContainer={getPopupContainer}>
                <Button style={{ marginBottom: 20 }}>Click to show</Button>
            </Tooltip>
            <br />
            <Tooltip content={'hi bytedance'} trigger="focus" getPopupContainer={getPopupContainer}>
                <Input style={{ width: 150, marginBottom: 20 }} placeholder="Focus to show" />
            </Tooltip>
            <br />
            <Tooltip
                content={'hi bytedance'}
                trigger="custom"
                visible={visible}
                getPopupContainer={getPopupContainer}
            >
                <span style={{ display: 'inline-block' }}>
                    <ButtonGroup>
                        <Button onClick={() => setVisible(true)}>Controlled show</Button>
                        <Button onClick={() => setVisible(false)}>Controlled hide</Button>
                    </ButtonGroup>
                </span>
            </Tooltip>
        </div>
    </div>
);
}

Override Style

Configure specific styles for the pop-up layer through the className and style API, such as overriding the default maxWidth (240px)

import React from 'react';
import { Tooltip, Tag } from '@douyinfe/semi-ui';

() => {
    return (
        <Tooltip
            style={{
                maxWidth: 320,
            }}
            className="another-classname"
            content={'hi semi semi semi semi semi semi semi'}
        >
            <Tag style={{ marginRight: '8px' }}>Custom Style And ClassName</Tag>
        </Tooltip>
    );
};

Render to Specified DOM

With getPopupContainer the bullet layer will be rendered to the DOM returned by the function.

It should be noted that: The returned container, if not document.body,position Will be set by default "relative"(Version > = 0.18.0).

import React from 'react';
import { Tooltip, Tag } from '@douyinfe/semi-ui';

function Demo() {
    return (
        <div id="tooltip-wrapper" style={{ position: 'relative' }}>
            <Tooltip
                position="right"
                content="Popup will be rendered in element#tooltip-wrapper"
                trigger="click"
                getPopupContainer={() => document.querySelector('#tooltip-wrapper')}
            >
                <Tag>Click here</Tag>
            </Tooltip>
        </div>
    );
}

Use with Popver or Popconfirm

Tooltip, Popconfirm, and Popover all need to hijack related events of children (onMouseEnter / onMouseLeave / onClick ....) to configure trigger. If used directly, it will invalidate the outer trigger.
Need to add a layer of elements (div or span) in the middle to prevent trigger event hijack failure.

import React from 'react';
import { Popconfirm, Tooltip, Button } from '@douyinfe/semi-ui';

() => (
    <Popconfirm content="Are you sure to delete this comment" title='Confirm Delete'>
        <span style={{ display: 'inline-block' }}>
            <Tooltip content={'Delete Comment'}>
                <Button type="danger">Delete</Button>
            </Tooltip>
        </span>
    </Popconfirm>
);

ARIA

Tooltip has a tooltip role, following the definition of Tooltip in the WAI-ARIA specification
Tooltip's content and children
- about content
  - The wrapper of content will be automatically added with id attribute to match the aria-describedby of children and associate content with children
- about children
  - There should be an explicit connection between the content of the Tooltip and its children. Tooltip will automatically add the aria-describedby attribute to the children element, the value is the id of the content wraper.
  - If the children of your Tooltip are Icon and do not contain visible text, we recommend that you add the aria-label attribute to the children to describe accordingly
```
// Good practices, add aria-label to description tooltip children
/* eslint-disable */
<Tooltip content={<p id='description'>Edit your setting</p>}>
<IconSetting aria-label='Settings'> 
</IconSetting>
</Tooltip>
```

Content Guidelines

Only display information description and guidance, do not display error information
Only extra links and buttons not in tooltip
Try to simplify the description to one sentence without showing punctuation marks

FAQ

Why do some forms of content not wrap when the content in Tooltip and Typography is very long?
Before the v2.36.0 version, considering that different language content (e.g. English, Chinese, combination of English and Chinese) have inconsistent requirements for line breaks, so Semi does not use a default setting. After receiving a lot of usage feedback, since the v2.36.0 version, Tooltip has internally set word-wrap handles text wrapping for break-word. For any version, if the default settings are not as expected, the user can adjust the line break related CSS properties through the style/className API.
