Fixed options mean putting our defined options in the searchbox in ReactJS. Fixed options can not be altered in the search bar. Material UI for React has this component available for us and it is very easy to integrate. We can put fixed options in the search box in ReactJS 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 npm install @material-ui/lab
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 = () => { // Fixed Options to show const fixedOption = ['Gourav'] // Sample options for search box const myOptions = [ 'Gourav', 'Niharika', 'kartik', 'Madhuri', 'Karishma', 'Dinesh' ]; const [value, setValue] = React.useState(fixedOption); return ( <div style={{ marginLeft: '40%', marginTop: '60px' }}> <h3>Greetings from neveropen!</h3> <Autocomplete multiple id="fixed-tags-demo" value={value} onChange={(event, newValue) => { setValue([ ...fixedOption, ...newValue.filter((option) => fixedOption.indexOf(option) === -1), ]); }} options={myOptions} getOptionLabel={(option) => option} renderTags={(tagValue, getTagProps) => tagValue.map((option, index) => ( <Chip label={option} {...getTagProps({ index })} disabled={fixedOption.indexOf(option) !== -1} /> )) } style={{ width: 450 }} renderInput={(params) => ( <TextField {...params} label="Fixed Option Demo" variant="outlined" placeholder="Enter Option" /> )} /> </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:
As you can see now in the above searchbox, our fixed options array is already fixed in the search bar, so this is how we can put already fixed tags in ReactJS.
