A multiple column draggable drag and drop component built with **native HTML5 drag-and-drop API**

**✨ New in v2.0:** Now uses native HTML5 drag-and-drop instead of react-beautiful-dnd - fully compatible with React 18/19 and StrictMode!

Just send a JSON in the given structure to create draggable and droppable column, the column will create as the length of the JSON that pass in props

Create a custom component as dragable items and provide it to the HOC wrapper in props

### Usage

#### Basic Example (Default Rendering)

```jsx
import DragDropComponent from "react-drag-and-drop-multiple-dynamic-column";

const data = [
  {
    id: "1",
    name: "Drag drop 1",
    data: [
      {
        id: "1",
        value: "Test 1",
      },
      {
        id: "2",
        value: "Test 2",
      },
      {
        id: "3",
        value: "Test 3",
      },
    ],
  },
  {
    id: "2",
    name: "Drag drop 2",
    data: [
      {
        id: "5",
        value: "Test 4",
      },
      {
        id: "6",
        value: "Test 5",
      },
    ],
  },
  {
    id: "3",
    name: "Drag drop 3",
    data: [
      {
        id: "7",
        value: "Test 6",
      },
      {
        id: "8",
        value: "Test 7",
      },
    ],
  },
];

const App = () => (
  <DragDropComponent
    onChange={(data) => console.log(data)}
    width="100%"
    height={"100%"}
    data={data}
    multiple
    draggerImg
    title
  >
    Try your custom drag item html component here
  </DragDropComponent>
);

createRoot(document.getElementById("root")).render(<App />);
```

#### Custom Rendering (NEW! 🎉)

The library now supports **custom rendering** - you can render anything you want inside draggable items!

```jsx
import DragDropComponent from "react-drag-and-drop-multiple-dynamic-column";

const data = [
  {
    id: "1",
    name: "Todo",
    data: [
      {
        id: "1",
        title: "Design System",
        description: "Create component library",
        priority: "high",
        assignee: "John Doe",
      },
      // ... more items
    ],
  },
  // ... more lists
];

// Define your custom render function
const renderTaskCard = (item, index, listId) => (
  <div
    style={{
      padding: "16px",
      backgroundColor: "white",
      borderRadius: "8px",
      border: "1px solid #e0e0e0",
    }}
  >
    <h3>{item.title}</h3>
    <p>{item.description}</p>
    <div style={{ display: "flex", justifyContent: "space-between" }}>
      <span>👤 {item.assignee}</span>
      <span
        style={{
          color: item.priority === "high" ? "#ff4757" : "#2ed573",
        }}
      >
        {item.priority}
      </span>
    </div>
  </div>
);

// Use it!
<DragDropComponent
  data={data}
  renderItem={renderTaskCard} // 🎉 Custom render!
  onChange={(data) => console.log(data)}
  width="100%"
  height="600px"
  multiple
  title
/>;
```
