The custom filter means adding our own business login to filter the options shown in searchbox or any dropdown menu. Material UI for React has this component available for us and it is very easy to integrate. We can create our own custom filter for options 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 Autocomplete, { createFilterOptions } from '@material-ui/lab/Autocomplete';const App = () => { const filterOptions = createFilterOptions({ matchFrom: 'start', stringify: option => option, }); // Sample options for search box const myOptions = ['One Number', 'Two Number', 'Five Number', 'This is a sample text', 'Dummy text', 'Dropdown option teet', 'Hello text', 'Welcome to text field']; return ( <div style={{ marginLeft: '40%', marginTop: '60px' }}> <h3>Greetings from neveropen!</h3> <Autocomplete style={{ width: 500 }} freeSolo filterOptions={filterOptions} options={myOptions} renderInput={(params) => ( <TextField {...params} variant="outlined" label="Search Box" /> )} /> </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:
The following would have been the output without adding our custom filter function:
