In this article, we’ll walk you through simple and practical ways to add drag and drop features to your React projects. Whether you are just getting started with HTML5 drag-and-drop or want to explore advanced libraries like react-beautiful-dnd, we’ll explain everything in plain English — with easy code examples and tips to avoid common mistakes.
By the end, you’ll be ready to convert your static interface into a dynamic, modern UI with smooth drag-and-drop functionality.
✅ TLDR (Too Long Didn’t Read)
This article explains how to implement drag and drop in React.js using both built-in HTML5 APIs and popular libraries like react-dnd and react-beautiful-dnd. It covers use cases, setup steps, sample code, common problems, and practical tips — all in simple, easy-to-understand language.
Why Drag and Drop Is Useful in Web Applications
Drag and drop is a small feature that makes a big difference in user experience. Instead of clicking buttons or filling forms to move things around, users can simply pick up an item and place it where they want. It feels natural — just like moving files on your computer desktop.
📌 Real-World Use Cases:
In short, drag and drop helps make the UI more interactive, fun, and faster to use. For users, it reduces effort. For developers, it’s a chance to offer a premium, app-like experience — right in the browser.
In Indian startups or tech companies, where apps are often being built for scale and simplicity, adding drag and drop can make your product feel polished and modern without too much extra coding.
How Drag and Drop Works in React.js
Before jumping into code, it’s important to understand how drag and drop works behind the scenes, especially when using it in a React app.
🧠 The Basic Idea
At the core, drag and drop relies on browser events. These events tell the browser:
HTML5 already provides these events — like onDragStart, onDragOver, and onDrop. React supports these too. But since React uses a virtual DOM, we need to make sure we’re handling these events properly inside our components.
🧩 Key Events in React
Here are some important drag and drop events you’ll use in React:
🖼️ Think of It Like This:
React makes it easy to bind these events to your components using JSX, and we can use useState to update what gets moved where.
In short, drag and drop in React is all about:
Once you get this logic, you can build your own custom drag and drop — or plug in a library to make it easier.
Using Basic HTML5 Drag and Drop in React
If you want to keep things simple and avoid using any external libraries, you can use the HTML5 drag and drop API directly in React. It’s a good way to learn the basics and see how everything works.
Let’s look at a basic example where you can drag a box and drop it into another area.
🧪 Example: Drag a Box to a Drop Area
import React, { useState } from 'react';
function DragDropBasic() {
const [dropped, setDropped] = useState(false);
const handleDragStart = (e) => {
e.dataTransfer.setData('text/plain', 'This box is being dragged');
};
const handleDragOver = (e) => {
e.preventDefault(); // Needed to allow drop
};
const handleDrop = (e) => {
e.preventDefault();
setDropped(true);
};
return (
<div style={{ padding: '30px' }}>
<div
draggable
onDragStart={handleDragStart}
style={{
width: '100px',
height: '100px',
backgroundColor: '#2196f3',
color: '#fff',
padding: '20px',
textAlign: 'center',
cursor: 'move',
marginBottom: '20px',
}}
>
Drag Me
</div>
<div
onDragOver={handleDragOver}
onDrop={handleDrop}
style={{
width: '200px',
height: '150px',
border: '2px dashed #ccc',
display: 'flex',
alignItems: 'center',
justifyContent: 'center',
backgroundColor: dropped ? '#e0ffe0' : '#f9f9f9',
}}
>
{dropped ? 'Dropped!' : 'Drop Here'}
</div>
</div>
);
}
export default DragDropBasic;
🧠 What’s Happening:
👍 Pros:
👎 Limitations:
Making Life Easier with react-dnd Library
As your app becomes more complex, handling drag and drop using plain HTML5 events can get messy. That’s where react-dnd comes in. It’s a powerful library built for React that helps you manage complex drag-and-drop logic without the headache.
🧩 What Is react-dnd?
react-dnd (short for React Drag and Drop) gives you a clean way to:
It uses the concept of "drag sources" and "drop targets" — kind of like who is being dragged and where it can go.
⚙️ How to Install:
npm install react-dnd react-dnd-html5-backend
📦 Simple Usage Example
Here’s a basic setup to drag a card from one place to another:
import { DndProvider, useDrag, useDrop } from 'react-dnd';
import { HTML5Backend } from 'react-dnd-html5-backend';
const ItemType = { CARD: 'card' };
function DraggableCard({ id, text }) {
const [{ isDragging }, drag] = useDrag(() => ({
type: ItemType.CARD,
item: { id },
collect: (monitor) => ({
isDragging: monitor.isDragging(),
}),
}));
return (
<div
ref={drag}
style={{
opacity: isDragging ? 0.5 : 1,
padding: '10px',
margin: '5px',
backgroundColor: '#ffecb3',
cursor: 'move',
}}
>
{text}
</div>
);
}
function DropZone({ onDrop }) {
const [, drop] = useDrop(() => ({
accept: ItemType.CARD,
drop: (item) => onDrop(item.id),
}));
return (
<div
ref={drop}
style={{
height: '150px',
border: '2px dashed #aaa',
padding: '10px',
}}
>
Drop Here
</div>
);
}
function App() {
const handleDrop = (id) => {
alert(`Card ${id} dropped`);
};
return (
<DndProvider backend={HTML5Backend}>
<DraggableCard id="1" text="Drag this card" />
<DropZone onDrop={handleDrop} />
</DndProvider>
);
}
✅ Why Use react-dnd?
⚠️ Heads Up:
It may feel a bit heavy when you first use it — especially with hooks like useDrag and useDrop. But once you get used to its structure, it’s super powerful.

Let's Build a Task Board: Drag and Drop in Action
Creating a Task Board involves setting up a React application with draggable task cards and droppable columns. We'll use the Pragmatic Drag and Drop library to handle the drag-and-drop interactions efficiently.
To set up a React project with Vite and integrate the Pragmatic Drag and Drop library, follow these steps:
1. Initialize a React Project with Vite
Create the Project:
npm create vite@latest task-board -- --template react
This command creates a new directory named task-board with a React template.
Navigate to the Project Directory:
cd task-board
Install Dependencies:
Install the necessary packages, including React and ReactDOM:
npm install
2. Install Pragmatic Drag and Drop Library
Add the Pragmatic Drag and Drop library and its dependencies:
npm install @atlaskit/pragmatic-drag-and-drop @atlaskit/pragmatic-drag-and-drop-hitbox tiny-invariant
3. Configure Vite for Pragmatic Drag and Drop
The Pragmatic Drag and Drop library uses specific module paths that may require aliasing in Vite. To ensure compatibility:
Update vite.config.js:
Modify the vite.config.js file to include the following alias configuration:
import { defineConfig } from 'vite';
import react from '@vitejs/plugin-react';
export default defineConfig({
plugins: [react()],
resolve: {
alias: [
{
find: /^@atlaskit\/pragmatic-drag-and-drop\/(.*)/,
replacement: 'node_modules/@atlaskit/pragmatic-drag-and-drop/dist/esm/entry-point/$1.js',
},
],
},
});
This alias ensures that the module paths resolve correctly, preventing potential import errors.
4. Implement Drag and Drop Components
With the project set up and dependencies installed, you can now create the components for the task board:
This component represents an individual task and is draggable:
Recommended by LinkedIn
import React, { useEffect, useRef } from 'react';
import { draggable } from '@atlaskit/pragmatic-drag-and-drop/element/adapter';
function TaskCard({ task }) {
const cardRef = useRef(null);
useEffect(() => {
const cleanup = draggable({
element: cardRef.current,
onDragStart: () => console.log(`Dragging task: ${task.id}`),
onDrop: () => console.log(`Dropped task: ${task.id}`),
});
return () => cleanup();
}, [task.id]);
return (
<div
ref={cardRef}
style={{
padding: '10px',
margin: '5px',
backgroundColor: '#f0f0f0',
cursor: 'grab',
}}
>
{task.content}
</div>
);
}
export default TaskCard;
This component serves as a drop zone for tasks:
import React, { useEffect, useRef } from 'react';
import { dropTargetForElements } from '@atlaskit/pragmatic-drag-and-drop/element/adapter';
import TaskCard from './TaskCard';
function Column({ column, tasks, onTaskDrop }) {
const columnRef = useRef(null);
useEffect(() => {
const cleanup = dropTargetForElements({
element: columnRef.current,
onDrop: (data) => {
console.log(`Task dropped in column: ${column.id}`);
onTaskDrop(data, column.id);
},
});
return () => cleanup();
}, [column.id, onTaskDrop]);
return (
<div
ref={columnRef}
style={{
margin: '10px',
padding: '10px',
backgroundColor: '#e3e3e3',
minHeight: '200px',
width: '250px',
}}
>
<h3>{column.title}</h3>
{tasks.map((task) => (
<TaskCard key={task.id} task={task} />
))}
</div>
);
}
export default Column;
This is the main component that manages the state of columns and tasks:
import React, { useState } from 'react';
import Column from './Column';
const initialData = {
tasks: {
'task-1': { id: 'task-1', content: 'Task 1' },
'task-2': { id: 'task-2', content: 'Task 2' },
'task-3': { id: 'task-3', content: 'Task 3' },
'task-4': { id: 'task-4', content: 'Task 4' },
},
columns: {
'column-1': {
id: 'column-1',
title: 'To Do',
taskIds: ['task-1', 'task-2'],
},
'column-2': {
id: 'column-2',
title: 'In Progress',
taskIds: ['task-3'],
},
'column-3': {
id: 'column-3',
title: 'Done',
taskIds: ['task-4'],
},
},
columnOrder: ['column-1', 'column-2', 'column-3'],
};
function TaskBoard() {
const [data, setData] = useState(initialData);
const onTaskDrop = (taskId, destinationColumnId) => {
const sourceColumnId = Object.keys(data.columns).find((columnId) =>
data.columns[columnId].taskIds.includes(taskId)
);
if (sourceColumnId === destinationColumnId) return;
const sourceTaskIds = Array.from(data.columns[sourceColumnId].taskIds);
const destinationTaskIds = Array.from(
data.columns[destinationColumnId].taskIds
);
sourceTaskIds.splice(sourceTaskIds.indexOf(taskId),
Best Practices for Implementing Drag-and-Drop in React

Specify the area within which the draggable item is allowed to move. This can be a parent container or specific coordinates.
2. Apply Constraints:
Utilize the library's configuration options to enforce these boundaries, ensuring that the draggable item cannot be moved outside the defined area.
🧲 Snap-to-Grid Functionality
For interfaces that require precise alignment, implementing a snap-to-grid feature can be beneficial. This ensures that draggable items align to a predefined grid layout upon being dropped.
Implementation Steps:
1. Define Grid Dimensions:
Set the width and height of the grid cells to which items should snap.
2. Calculate Snap Position:
During the drag operation, calculate the nearest grid position based on the item's current position.
3. Adjust Item Position on Drop:
Upon dropping the item, adjust its final position to align with the nearest grid coordinates.
🎛️ Handling Nested Drag-and-Drop Scenarios
In complex interfaces, you might encounter nested draggable and droppable areas. Managing these interactions requires careful handling to ensure the correct behavior.
Implementation Steps:
1. Define Parent and Child Draggables/Droppables:
Clearly specify which elements are parents and which are children in the drag-and-drop hierarchy.
2. Manage Event Propagation:
Control the propagation of drag events to prevent unintended behaviors, ensuring that events are handled at the appropriate level in the hierarchy.
3. Coordinate State Management:
Maintain a consistent state that reflects the current structure and relationships of the draggable items, updating it appropriately during drag-and-drop operations.
By leveraging these advanced features and customization options, you can create a more dynamic and user-friendly drag-and-drop experience in your React application. Tailoring these functionalities to your specific use case will enhance both the usability and aesthetic appeal of your interface.
