React Suite Dropdown Submenu

0 0 2 minutes read

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. The dropdown component allows the user to provide navigation that uses a select picker if you want to select a value. The dropdown submenu is used to create a nested menu. Meaning menu inside a menu.

Syntax:

<Dropdown title="zambiatek">
    <Dropdown.Item>Item 1</Dropdown.Item>
    <Dropdown.Menu title="SubMenu">
        <Dropdown.Item>Item 2A</Dropdown.Item>
        <Dropdown.Item>Item 2B</Dropdown.Item>
    </Dropdown.Menu>
</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 create a dropdown menu and create another menu as a dropdown item

JavaScript

import React from 'react'; 
import Dropdown from 'rsuite/Dropdown'; 
import 'rsuite/dist/rsuite.min.css'; 
  
function App() { 
    return ( 
        <div> 
            <h1 style={{ color: 'green' }}> 
                zambiatek</h1> 
            <h3>React Suite Dropdown Submenu</h3> 
            <Dropdown title="zambiatek"> 
                <Dropdown.Item>Item 1</Dropdown.Item> 
                <Dropdown.Menu title="Item 2"> 
                    <Dropdown.Item>Item 2A</Dropdown.Item> 
                    <Dropdown.Item>Item 2B</Dropdown.Item> 
                </Dropdown.Menu> 
                <Dropdown.Item>Item 3</Dropdown.Item> 
                <Dropdown.Menu title="Item 4"> 
                    <Dropdown.Menu title="Item 4A"> 
                        <Dropdown.Item>Item 4A-A</Dropdown.Item> 
                        <Dropdown.Item>Item 4A-B</Dropdown.Item> 
                    </Dropdown.Menu> 
                    <Dropdown.Item>Item 4B</Dropdown.Item> 
                </Dropdown.Menu> 
  
            </Dropdown> 
        </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 learn, how can we disable some Menu items/ entire sub-menu.

JavaScript

import React from 'react'; 
import Dropdown from 'rsuite/Dropdown'; 
import 'rsuite/dist/rsuite.min.css'; 
  
function App() { 
    return ( 
        <div> 
            <h1 style={{ color: 'green' }}> 
                zambiatek</h1> 
            <h3>React Suite Dropdown Submenu</h3> 
            <Dropdown title="zambiatek"> 
                <Dropdown.Item>Database</Dropdown.Item> 
                <Dropdown.Menu title="DSA"> 
                    <Dropdown.Item disabled>C++</Dropdown.Item> 
                    <Dropdown.Item>Java</Dropdown.Item> 
                </Dropdown.Menu> 
                <Dropdown.Item >Blockchain Technology</Dropdown.Item> 
                <Dropdown.Menu title="Web Technology"> 
                    <Dropdown.Menu title="React" disabled> 
                        <Dropdown.Item >Material UI</Dropdown.Item> 
                        <Dropdown.Item>React Suite</Dropdown.Item> 
                    </Dropdown.Menu> 
                    <Dropdown.Item>HTML</Dropdown.Item> 
                </Dropdown.Menu> 
  
            </Dropdown> 
        </div> 
    ) 
} 
  
export default App;
