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 neveropen!</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.
