How to disable dropdown options in ReactJS?

Disable options means the dropdown options become disable i.e. not clickable. Basically a disable option is unusable and un-clickable. Material UI for React has this component available for us and it is very easy to integrate. We can make an option disable in dropdown 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.

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 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
        style={{ width: 400 }}
        options={myOptions}
        getOptionDisabled={(option) => {
          // Mention options which needs to be disable
          return option === myOptions[1] || option === myOptions[3]
        }}
        renderInput={(params) => (
          <TextField {...params} label="Disabled options"
          variant="outlined" />
        )}
      />
    </div>
  );
}

export default App

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

npm start
