Getting started with React Tooltip component

20 Apr 2021 / 4 minutes to read

This section briefly explains how to create a simple Tooltip component and configure its available functionalities in React.

Tooltips can be initialized on,

A single element (or)
A container that has more than one sub-element within it and the sub-elements are considered as targets.

Dependencies

The following list of dependencies are required to use the Tooltip component in your application.

|-- @syncfusion/ej2-react-popups
|-- @syncfusion/ej2-base
|-- @syncfusion/ej2-react-base
|-- @syncfusion/ej2-popups
    |-- @syncfusion/ej2-buttons

Installation and configuration

You can use Create-react-app to setup the applications. To install create-react-app run the following command.

npm install -g create-react-app

Start a new project using create-react-app command as follows

create-react-app quickstart --scripts-version=react-scripts-ts
cd quickstart

create-react-app quickstart

cd quickstart

Install the below required dependency package in order to use the Tooltip component in your application.

npm install @syncfusion/ej2-react-popups --save

The above package installs tooltip dependencies which are required to render the Tooltip component in React environment.

Tooltip CSS files are available in the ej2-react-popups package folder. Import the Tooltip component’s required CSS references as follows in src/App.css.

@import "../node_modules/@syncfusion/ej2-base/styles/material.css";
@import "../node_modules/@syncfusion/ej2-react-popups/styles/material.css";

We can also use CRG to generate combined component styles.

Import the Tooltip component to your src/App.tsx file using following code.

import * as React from 'react';
import { TooltipComponent } from '@syncfusion/ej2-react-popups';
import './App.css';

export default class App extends React.Component<{}, {}> {
  render() {
let style: object = {
  display: 'inline-block',
  margin: '60px'
};
return (
  <TooltipComponent content="Tooltip Content" style={style}>
    Show Tooltip
  </TooltipComponent>
);
  }
}

import * as React from 'react';
import { TooltipComponent } from '@syncfusion/ej2-react-popups';
import './App.css';
export default class App extends React.Component {
    render() {
        let style = {
            display: 'inline-block',
            margin: '60px'
        };
        return (<TooltipComponent content="Tooltip Content" style={style}>
    Show Tooltip
  </TooltipComponent>);
    }
}

Now, run the application in the browser using the following command.

npm start

The output will be as follows:

You can create Tooltips on multiple targets within a container. To do so, you have to define specific target elements to the target property so that the Tooltip is initialized only on matched targets within a container. In this case, the Tooltip content is assigned from the title attribute of the target element.

Refer to the following code example to create a Tooltip on multiple targets within a container.
