React-Select is profoundly easy to use dropdown library exclusively built for React. The react-select library offers powerful multi-select, autocomplete, and AJAX support without any hassle.

• Simple customization with API support.
• Managing component state is super easy.
• Async data loading support.
• CSS Animation support for components.

React Dropdown Select Example

In this React tutorial, we will learn to work with React-select library in this tutorial. First, we will set up React JS project, and then inside the React app, we will install the React-select library to show you the React Dropdown select examples.

React App Set Up

Run the following command to install React project.

npx create-react-app react-select-tutorial

Get inside the project folder.

cd react-select-tutorial

Run the React project.

npm start

Install React-Select Library

Now, run the following command to install React-Select package via NPM.

npm install react-select --save
##### or #####
yarn add react-select

Install Bootstrap 4 from NPM to use the ready-made UI components.

npm install bootstrap --save
##### or #####
yarn add bootstrap

Import React-Select Library

One the React-select library is installed, we can now import the react-select module in src/App.js file. Include the following code in App.js file.

import React, { Component } from 'react';
import Select from 'react-select';
import 'bootstrap/dist/css/bootstrap.min.css';
const Countries = [
  { label: "Albania", value: 355 },
  { label: "Argentina", value: 54 },
  { label: "Austria", value: 43 },
  { label: "Cocos Islands", value: 61 },
  { label: "Kuwait", value: 965 },
  { label: "Sweden", value: 46 },
  { label: "Venezuela", value: 58 }
];
class App extends Component {
  render() {
    return (
      <div className="container">
        <div className="row">
          <div className="col-md-3"></div>
          <div className="col-md-6">
            <Select options={Countries} />
          </div>
          <div className="col-md-4"></div>
        </div>
      </div>
    );
  }
}
export default App

In the above code, we have imported the react-select and Bootstrap 4 modules in the App.js file. We defined a Countries array and passed the countries name along with their respective country code. We will show these countries name when a user clicks on the React dropdown select element with the help of the react-select library.

We declared the render() method and passed the HTML code inside of it such as container, row, and column from Bootstrap library to create the basic layout in our React app.

Then, we declared the React select dropdown with the options={...} object and inside the options tag we passed the Countries array. This will do the magic and render the countries names as you can see in the screenshot above.
