Implementing Tooltips in React JS | Updated 2024

68

Tooltips are small informational boxes that appear when users hover over, focus on, or tap an element within applications. They are crucial for enhancing user experience by providing additional information without cluttering the UI. This article will guide you through the steps to implement custom tooltips in a React application.

Setting Up Your React Environment

First, ensure you have a React project environment ready. If not, set up a new one using:

npx create-react-app react-tooltips
cd react-tooltips

Step by Step Guide Tooltips in React JS

Step 1: Create a Tooltip Component

Begin by creating a new component called Tooltip.js. This component will manage the visibility of the tooltip and display a message next to the cursor or attached to a component.

import React, { useState, useRef } from 'react';
import './Tooltip.css';

const Tooltip = ({ children, text }) => {
  const [showTooltip, setShowTooltip] = useState(false);
  const tooltipRef = useRef(null);

  const handleMouseOver = () => {
    setShowTooltip(true);
  };

  const handleMouseOut = () => {
    setShowTooltip(false);
  };

  return (
    <div className="tooltip-container" onMouseOver={handleMouseOver} onMouseOut={handleMouseOut}>
      {children}
      {showTooltip && (
        <div className="tooltip-box" ref={tooltipRef}>
          {text}
        </div>
      )}
    </div>
  );
};

export default Tooltip;

Step 2: Add CSS for the Tooltip

Next, create Tooltip.css to style the tooltip. The tooltip box will appear dynamically based on user interactions:

.tooltip-container {
  position: relative;
  display: inline-block;
}

.tooltip-box {
  position: absolute;
  bottom: 100%;
  left: 50%;
  transform: translateX(-50%);
  margin-bottom: 5px;
  padding: 8px;
  background-color: black;
  color: white;
  text-align: center;
  border-radius: 6px;
  z-index: 1;
}

Step 3: Use the Tooltip Component

Now, you can use the Tooltip component in your application. For example, add it to your App.js:

import React from 'react';
import './App.css';
import Tooltip from './Tooltip';

function App() {
  return (
    <div className="App">
      <h1>React Tooltip Example</h1>
      <Tooltip text="This is a tooltip">
        <button>Hover over me!</button>
      </Tooltip>
    </div>
  );
}

export default App;

Conclusion

Tooltips in React can be implemented effectively with just a few steps, enhancing the user interface by providing helpful information without overcrowding the screen. This implementation can be extended with animations, positioning options, and more interactive elements to fit the needs of any application.
