How to create multiple dropdown options as a tag in ReactJS?

Choosing multiple options and creating your own options from the dropdown means allowing the user to choose more than one option from the dropdown and add his own options. Material UI for React has this component available for us and it is very easy to integrate. We can choose multiple options and create multiple options using the following approach.

Creating React Application and Installing Module:

Step 1: Create a React application using the following command:

npx create-react-app foldername

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

cd foldername

Step 3: After creating the ReactJS application, Install the material-ui modules using the following command:

npm install @material-ui/core

Project Structure: It will look like the following.

Project Structure

App.js: Now write down the following code in the App.js file. Here, App is our default component where we have written our code.

Javascript

import React from 'react'
import TextField from '@material-ui/core/TextField';
import Chip from '@material-ui/core/Chip';
import Autocomplete from '@material-ui/lab/Autocomplete';

const App = () => {

  // Sample options for dropdown
  const myOptions = ['One', 'Two', 'Three', 'Four', 'Five'];

  return (
    <div style={{ marginLeft: '40%', marginTop: '60px' }}>
      <h3>Greetings from GeeksforGeeks!</h3>
      <Autocomplete
        multiple
        freeSolo
        style={{width:500}}
        options={myOptions}
        defaultValue={[myOptions[2]]}
        renderTags={(value: string[], getTagProps) =>
          value.map((option: string, index: number) => (
            <Chip variant="outlined"
              label={option}
              {...getTagProps({ index })} />
          ))
        }
        renderInput={(params) => (
          <TextField {...params}
            variant="outlined"
            label="freeSolo"
            placeholder="Enter fields" />
        )}
      />
    </div>
  );
}

export default App

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:

In the above example, we have selected One and Two from the options available but also added our own options i.e. Random Number. This is how we can choose and create multiple options using Chip in ReactJS.
