React Suite Dropdown Option Active State

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.

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. 

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">Item A</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.Menu title="Active Menu" activeKey="e-2">
      <Dropdown title="SubMenu" activeKey="e-2">
      <Dropdown.Item eventKey="e-1">Item E-1</Dropdown.Item>
      <Dropdown.Item eventKey="e-2">Active Item</Dropdown.Item>
      </Dropdown>
      </Dropdown.Menu>
      </Dropdown>
      </ButtonToolbar>
      </div>
  )
}
export default App;
