Autocomplete Component is used for auto-completing the text value with the option value. It basically allows the user to type and select the item from a list of suggestions. It improves the user experience by giving suggestions while the user type.

In this article, you will examine how to style an Autocomplete component in ReactJS.

Creating React Application And Installing Module:

    npx create-react-app foldername

  • Step 2: After creating your project folder i.e. foldername, move to it using the following command:

Example: Now write down the following code in the App.js file. Here, App is our default component where we have written our code. Following code has Autocomplete Component with styling added.


import React, { useState } from 'react'
import Autocomplete from 'react-autocomplete'
function App() {
    // Defining a state named value, which
    // we can update by calling setValue 
    // Value will store the typed value or
    // selected suggestion by the user
    const [value, setValue] = useState('');
    return (
        <div style={{
            display: 'flex', flexDirection: 'column',
            alignItems: 'center'
                {/* Inline css*/}
                <h4 style={{
                    padding: '15px'
                    border: '13px solid #b4f0b4',
                    color: 'rgb(11, 167, 11)'

                    // displayed while the user type
                        { label: 'C++' },

                        { label: 'Python' },
                        { label: 'JavaScript' },

                        { label: 'Objective C' },
                        { label: 'C#' },
                        { label: 'Dart' },
                        { label: 'Perl' }
                    // To handle the case that when
                    // the user type, suggested 
                    // values should be independent
                    // of upper or lower case 
                    shouldItemRender={(item, value
                        ) => item.label.toLowerCase()
                        .indexOf(value.toLowerCase()) > -1}
                    getItemValue={item => item.label}
                    renderItem={(item, isHighlighted) =>
                        // Styling to highlight selected item
                        <div style={{
                            background: isHighlighted ?
                                '#bcf5bc' : 'white'
                    // The onChange event watches for
                    // changes in an input field
                    onChange={e => setValue(}
                    // To set the state variable to value
                    // selected from dropdown
                    onSelect={(val) => setValue(val)}
                    // Added style in Autocomplete component
                        style: {
                            width: '300px', height: '20px',
                            background: '#e4f3f7'
                            border: '2px outset lightgray'
                        placeholder: 'Search language'
export default App;


  • On the Autocomplete element, className doesn’t apply to the text input as you might expect. You can’t use the className on the autocomplete component, you have to use the inputProps property.
  • The inputProps is commonly used for (but not limited to) placeholder, event handlers (onFocus, onBlur, etc.), autoFocus, etc.
  • You can customize the styles in inputProps in the above code.
  • In the renderItem prop, you can add style as a set of styles that can be applied to improve the look of the items in the dropdown menu.

Step to Run Application: Run the application using the following command from the root directory of the project:

npm start

Output: Now open your browser and go to http://localhost:3000/, you will see the following output:

Autocomplete on select language
