rc-tooltip

What is rc-tooltip?

The rc-tooltip package is a React component for creating simple and customizable tooltips. It allows developers to easily add tooltip functionality to their React applications, providing users with additional context or information when they hover over or focus on an element. The package supports various customization options, including the tooltip's appearance, positioning, and animation.

What are rc-tooltip's main functionalities?

Basic Tooltip

This code sample demonstrates how to create a basic tooltip that appears on top of an element when it is hovered over. The tooltip's content is specified as 'Tooltip text'.

import React from 'react';
import Tooltip from 'rc-tooltip';
import 'rc-tooltip/assets/bootstrap.css';

const BasicTooltip = () => (
  <Tooltip placement="top" trigger={['hover']} overlay={<span>Tooltip text</span>}>
    <a href="#">Hover me</a>
  </Tooltip>
);

Customized Tooltip

This example shows how to create a tooltip that appears to the right of an element when clicked. The tooltip displays custom content, including a custom style and an arrow pointing to the target element.

import React from 'react';
import Tooltip from 'rc-tooltip';
import 'rc-tooltip/assets/bootstrap_white.css';

const CustomTooltip = () => (
  <Tooltip
    placement="right"
    trigger={['click']}
    overlay={<div style={{ height: 50, width: 100, backgroundColor: '#89CFF0' }}>Custom Content</div>}
    arrowContent={<div className="rc-tooltip-arrow-inner"></div>}
  >
    <a href="#">Click me</a>
  </Tooltip>
);

Dynamic Tooltip

This code snippet illustrates how to create a tooltip with dynamic visibility, controlled by the component's state. The tooltip appears when the mouse enters the target element and disappears when it leaves.

import React, { useState } from 'react';
import Tooltip from 'rc-tooltip';

const DynamicTooltip = () => {
  const [visible, setVisible] = useState(false);
  return (
    <Tooltip
      visible={visible}
      onVisibleChange={(vis) => setVisible(vis)}
      overlay={<span>Dynamic Content</span>}
    >
      <a href="#" onMouseEnter={() => setVisible(true)} onMouseLeave={() => setVisible(false)}>Hover or Leave</a>
    </Tooltip>
  );
};

Important Note

Tooltip requires a child node that accepts an onMouseEnter, onMouseLeave, onFocus, onClick event. This means the child node must be a built-in component like div or span, or a custom component that passes its props to its built-in component child.

Accessibility

For accessibility purpose you can use the id prop to link your tooltip with another element. For example attaching it to an input element:

<Tooltip
    ...
    id={this.props.name}>
    <input type="text"
           ...
           aria-describedby={this.props.name}/>
</Tooltip>

If you do it like this, a screenreader would read the content of your tooltip if you focus the input element.

NOTE: role="tooltip" is also added to expose the purpose of the tooltip element to a screenreader.
