Grouping dropdown options using ReactJS
  • Last Updated : 18 Jan, 2021

Grouping options means putting options in groups based on conditions for a better user experience. For example on our mobile, all contacts are grouped by their first letter so that it becomes easier for users to search for contacts. Material UI for React has this component available for us and it is very easy to integrate.

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

      initialLetter: /[0-9]/.test(initialLetter) ? 
      '0-9' : initialLetter,
      ...option,
    };
  });
