It provides pre-built components of React which can be used easily in any web application. In this article, we’ll learn about React suite Cascader Controlled.

Creating React Application and Installing Module:

Step 1: Create a react application using the given command:

npm create-react-app projectname

Step 2: After creating your project, move to it using the given command:

cd projectname

Step 3: Now Install the rsuite node package using the given command:

npm install rsuite

Project Structure: Now your project structure should look like the following:

 

Example 1: Below is the example that demonstrates the React Suite Controlled Cascader component.

Javascript




import "rsuite/dist/rsuite.min.css";
import { Cascader } from "rsuite";
import { useState } from "react";
  
const customData = [
    {
        label: "Data Structures",
        value: 1,
        children: [
            {
                label: "Queue",
                value: 2,
                children: [
                    {
                        label: "Priority Queue",
                        value: 3,
                    },
                    {
                        label: "FIFO Queue",
                        value: 4,
                    },
                ],
            },
            {
                label: "Linked List",
                value: 5,
                children: [
                    {
                        label: "Circular",
                        value: 6,
                    },
                    {
                        label: "Double",
                        value: 7,
                    },
                    {
                        label: "Single",
                        value: 8,
                    },
                ],
            },
        ],
    },
    {
        label: "Algorithms",
        value: 9,
        children: [
            {
                label: "Search",
                value: 2,
                children: [
                    {
                        label: "Binary Search",
                        value: 3,
                    },
                    {
                        label: "Linear Search",
                        value: 4,
                    },
                ],
            },
            {
                label: "Sorting",
                value: 5,
                children: [
                    {
                        label: "Bubble Sort",
                        value: 6,
                    },
                    {
                        label: "Selection Sort",
                        value: 7,
                    },
                    {
                        label: "Insertion Sort",
                        value: 8,
                    },
                ],
            },
        ],
    },
]
  
export default function App() {
    const [value, setValue] = useState(3);
  
    return (
        <div>
            <div style={
                {
                    textAlign: "center"
                }}>
                <h2>GeeksforGeeks</h2>
                <h4 style={{ color: "green" }}>
                    React Suite Cascader Controlled
                </h4>
            </div>
            <div style={
                {
                    padding: 20,
                    textAlign: "center"
                }}>
                <div>
                    <Cascader
                        value={value}
                        onChange={setValue}
                        style={{ width: 300 }}
                        data={customData}
                    />
                </div>
            </div>
        </div>
    );
}


Output:

 

Example 2: Below is another example that demonstrates the Controlled elements from two different lists in Cascader component.

Javascript




import "rsuite/dist/rsuite.min.css";
import { Cascader } from "rsuite";
import { useState } from "react";
  
const customData = [
    {
        label: "Data Structures",
        value: 1,
        children: [
            {
                label: "Queue",
                value: 2,
                children: [
                    {
                        label: "Priority Queue",
                        value: 3,
                    },
                    {
                        label: "FIFO Queue",
                        value: 4,
                    },
                ],
            },
            {
                label: "Linked List",
                value: 5,
                children: [
                    {
                        label: "Circular",
                        value: 6,
                    },
                    {
                        label: "Double",
                        value: 7,
                    },
                    {
                        label: "Single",
                        value: 8,
                    },
                ],
            },
        ],
    },
    {
        label: "Algorithms",
        value: 9,
        children: [
            {
                label: "Search",
                value: 10,
                children: [
                    {
                        label: "Binary Search",
                        value: 11,
                    },
                    {
                        label: "Linear Search",
                        value: 12,
                    },
                ],
            },
            {
                label: "Sorting",
                value: 13,
                children: [
                    {
                        label: "Bubble Sort",
                        value: 14,
                    },
                    {
                        label: "Selection Sort",
                        value: 15,
                    },
                    {
                        label: "Insertion Sort",
                        value: 16,
                    },
                ],
            },
        ],
    },
]
  
export default function App() {
    const [value, setValue] = useState(1_2);
  
    return (
        <div>
            <div style={
                {
                    textAlign: "center"
                }}>
                <h2>GeeksforGeeks</h2>
                <h4 style={
                    {
                        color: "green"
                    }}>
                    React Suite Cascader Controlled
                </h4>
            </div>
            <div style={
                {
                    padding: 20,
                    textAlign: "center"
                }}>
                <div>
                    <Cascader
                        value={value}
                        onChange={setValue}
                        style={{ width: 300 }}
                        data={customData}
                    />
                </div>
            </div>
        </div>
    );
}
