Drag and Drop is supported through two libraries. Those are
Draggable and Droppable. Draggable makes DOM to be
dragged using mouse or touch gestures and Droppable mark required DOM as droppable zone.
You can make any element draggable by passing the element to Draggable constructor. Refer the following code snippet to enable draggable for the DOM 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: 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>

ReactDom.render(<App />, document.getElementById('sample'));You can convert any DOM element as a droppable zone, which accepts the draggable elements. Refer the following code snippet to enable droppable zone.
import * as React from 'react';
import * as ReactDom from 'react-dom';
import { useEffect } from 'react';
import { Droppable } from '@syncfusion/ej2-base';
function App() {
useEffect(() => {

ReactDom.render(<App />, document.getElementById('sample'));To define a drop action set drop callback function during droppable object
creation. You can get details of dropped element through dropped element property in event argument.
Refer the following code snippet to use basic drag and drop action
import * as React from 'react';

import { useEffect } from 'react';
import { Draggable, Droppable } from '@syncfusion/ej2-base';
function App() {
useEffect(() => {

let droppable = new Droppable(document.getElementById('droppable'), {
drop: (e) => {
e.droppedElement.querySelector('#drag').textContent = 'Dropped';
}
});
}, []);
return (<div id='container'>
