React Suite Dropdown Option Active State

Last Updated : 04 Jul, 2022

React Suite is a popular front-end library with a set of React components that are designed for the middle platform and back-end products. Dropdown component allows the user to provide navigation that uses a select picker if you want to select a value.

React Suite Dropdown Option Active State helps to set a value active by default in a Dropdown menu. To make any element active for a dropdown menu, we need to define an activeKey for the dropdown menu and eventKey for the dropdown item.

Syntax:

<Dropdown title="GFG" activeKey="A">
    <Dropdown.Item eventKey="A">Active Item</Dropdown.Item>
</Dropdown>

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 required module using the following command:

npm install rsuite

Project Structure: It will look like the following.

Example 1: Now write down the following code in the App.js file. Here, App is our default component where we have written our code. In this example, we will display a dropdown menu, that will have 4 items. We will learn to make the first item active. We will provide an eventKey to this Dropdown component and add the same activeKey to Dropdown.

HTML

import React from 'react'; 
import Dropdown from 'rsuite/Dropdown'; 
import ButtonToolbar from 'rsuite/ButtonToolbar'; 
import 'rsuite/dist/rsuite.min.css'; 
  
import Link from '@mui/material/Link'; 
function App() { 
  return ( 
     <div> 
      <h1 style={{ color: 'green' }}>GeeksforGeeks</h1> 
      <h3>React Suite Dropdown Option Active State</h3> 
      <ButtonToolbar> 
       <Dropdown title="GeeksforGeeks" activeKey="a"> 
      <Dropdown.Item eventKey="a">Active Item</Dropdown.Item> 
      <Dropdown.Item eventKey="b">Item B</Dropdown.Item> 
      <Dropdown.Item eventKey="c">Item C</Dropdown.Item> 
      <Dropdown.Item eventKey="d">Item D</Dropdown.Item> 
    </Dropdown> 
    </ButtonToolbar> 
    </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:

Example 2: In this example, we will create an active key in a submenu.
