Autocomplete functionality can greatly enhance the user experience when filling out forms in a web application. It allows users to easily and quickly find and select the desired option from a predefined list. In this blog post, we will explore how to implement form autocomplete in React.js using the react-autocomplete library.

Getting Started

Before we dive into the implementation details, make sure you have a basic understanding of React.js and have a React.js project set up.

To get started, you need to install the react-autocomplete library using npm or yarn. Open your terminal and run the following command:

npm install react-autocomplete

Once the installation is complete, you can import the Autocomplete component from the library into your React component.

import React from 'react';
import Autocomplete from 'react-autocomplete';

const MyForm = () => {
  const items = [
    { label: 'Apple', value: 'apple' },
    { label: 'Banana', value: 'banana' },
    { label: 'Orange', value: 'orange' },
    // Add more items as needed
  ];

  return (
    <form>
      <Autocomplete
        items={items}
        getItemValue={(item) => item.label}
        renderItem={(item, isHighlighted) => (
          <div
            style=
          >
            {item.label}
          </div>
        )}
        onSelect={(value) => {
          // Handle when an item is selected
        }}
        renderInput={(props) => (
          <input
            {...props}
            placeholder="Type a fruit"
          />
        )}
      />
    </form>
  );
};

export default MyForm;

In the code above, we define an array of items which represents the autocomplete options. Each item has a label and a value.

The Autocomplete component receives the items array as a prop, along with callback functions to retrieve the item value, render each item, and handle the item selection.

The renderInput callback is used to render the input element with the placeholder text.

Finally, you can use the Autocomplete component inside your form to add autocomplete functionality to an input field.

Don’t forget to style the autocomplete list using CSS to enhance the visual appearance and usability of the autocomplete feature.
