Drag and Drop in React
23 Feb 202316 minutes to read
Drag and drop is a feature of a user interface that allows users to select an item or items and then move them to a different location or onto another interface element by “dragging” the selected item(s) with a pointing device (such as a mouse) and then “dropping” them at the desired location.
Syncfusion React components support drag and drop feature through two libraries. These are Draggable and Droppable.
Draggable
The Syncfusion’s Draggable library allows users to make any DOM element draggable by passing it as a parameter to the Draggable constructor. This can be useful for creating interactive and user-friendly interfaces, such as allowing a user to reorder items in a list by dragging them. The below code snippet enables the draggable functionality for the specific DOM element passed to the Draggable constructor.
import * as React from 'react';
import { useEffect } from 'react';
import * as ReactDom from 'react-dom';
import { Draggable } from '@syncfusion/ej2-base';
function App() {
useEffect(() => {
let draggable = new Draggable(document.getElementById('element'), { clone: false });
}, []);
return (<div id='container'>
<div id='element'><p>Draggable Element</p></div>
</div>);
}
export default App;
ReactDom.render(<App />, document.getElementById('sample'));import * as React from 'react';
import { useEffect } from 'react';
import * as ReactDom from 'react-dom';
import { Draggable } from '@syncfusion/ej2-base';
function App() {
useEffect(() => {
let draggable: Draggable = new Draggable(document.getElementById('element'),{ clone: false });
},[])
return (
<div id='container'>
<div id='element'><p>Draggable Element</p></div>
</div>
);
}
export default App;
ReactDom.render(<App />, document.getElementById('sample'));<!DOCTYPE html>

</html>Clone draggable element
Syncfusion provides the option to create a clone of a draggable element while the user is dragging it. It can be achieved by setting the clone property to true. Here’s an example of how to create a clone of a draggable element.
import * as React from 'react';
import { useEffect } from 'react';
import * as ReactDom from 'react-dom';
import { Draggable } from '@syncfusion/ej2-base';
function App() {
useEffect(() => {
let draggable = new Draggable(document.getElementById('element'), { clone: true });
}, []);
return (<div id='container'>
<div id='element'><p>Draggable Element</p></div>
</div>);
}
export default App;
ReactDom.render(<App />, document.getElementById('sample'));import * as React from 'react';
import { useEffect } from 'react';
import * as ReactDom from 'react-dom';
import { Draggable } from '@syncfusion/ej2-base';
function App() {
useEffect(() => {
let draggable: Draggable = new Draggable(document.getElementById('element'),{ clone: true });
},[])
return (
<div id='container'>
<div id='element'><p>Draggable Element</p></div>
</div>
);
}
export default App;
ReactDom.render(<App />, document.getElementById('sample'));<!DOCTYPE html>

</html>Drag area
A drag area is a specific area within a user interface that is designated for drag and drop operations. When an object or element is dragged within a drag area, certain actions or events may be triggered. The user can specify the drag area by using the dragArea property. Refer to the below sample.
import * as React from 'react';
import * as ReactDom from 'react-dom';
import { useEffect } from 'react';
import { Draggable } from '@syncfusion/ej2-base';
function App() {
useEffect(() => {
let draggable = new Draggable(document.getElementById('draggable'), { clone: false, dragArea: "#droppable" });
}, []);
return (<div id='container'>
<div id='droppable'><p>Drag Area </p></div>
<div id='draggable'><p id='drag'>Draggable Element </p></div>
</div>);
}
export default App;
ReactDom.render(<App />, document.getElementById('sample'));import * as React from 'react';
import * as ReactDom from 'react-dom';
import { useEffect } from 'react';
import { Draggable } from '@syncfusion/ej2-base';
function App() {
useEffect(() => {
let draggable: Draggable = new Draggable(document.getElementById('draggable'),{ clone: false, dragArea: "#droppable" });
},[])
return (
<div id='container'>
<div id='droppable'><p>Drag Area </p></div>
<div id='draggable'><p id='drag'>Draggable Element </p></div>
</div>
);
}
export default App;

</html>Droppable
Droppable component refers to an area of a user interface that can receive a draggable component that is being moved by a user. Syncfusion’s Droppable library converts any DOM element into a droppable zone, which accepts draggable elements.
When a draggable component is moved over a droppable component, the drop event can be triggered. The user can get details about the dropped element through the event argument. Based on the event argument, the user can append the dragged element to the target element.
Refer to the following code snippet to enable droppable zones.
import * as React from 'react';
import * as ReactDom from 'react-dom';
import { useEffect } from 'react';
import { Draggable, Droppable } from '@syncfusion/ej2-base';
function App() {
useEffect(() => {
let draggable = new Draggable(document.getElementById('draggable'), { clone: false });
let droppable = new Droppable(document.getElementById('droppable'), {
drop: (e) => {
e.droppedElement.querySelector('#drag').textContent = 'Dropped';
}
});
}, []);
return (<div id='container'>
<div id='droppable'><p>Droppable Target </p></div>
<div id='draggable'><p id='drag'>Draggable Element </p></div>
</div>);
}
export default App;
ReactDom.render(<App />, document.getElementById('sample'));import * as React from 'react';
import * as ReactDom from 'react-dom';
import { useEffect } from 'react';
import { Draggable, Droppable, DropEventArgs } from '@syncfusion/ej2-base';
function App() {
useEffect(() => {
let draggable: Draggable = new Draggable(document.getElementById('draggable'),{ clone: false });
let droppable: Droppable = new Droppable(document.getElementById('droppable'), {
drop: (e: DropEventArgs) => {
e.droppedElement.querySelector('#drag').textContent = 'Dropped';
}
});
},[])
return (
<div id='container'>
<div id='droppable'><p>Droppable Target </p></div>
<div id='draggable'><p id='drag'>Draggable Element </p></div>
</div>
);
}
export default App;
