I'll update the code to use react-draggable with the nodeRef prop, which is the recommended way to avoid the findDOMNode error in React 18+.

I've updated the code to continue using react-draggable while fixing the findDOMNode error. The key change is adding the nodeRef prop to each Draggable component, which is the recommended approach for React 18+.

Key changes:

1. Added useRef to create and manage refs for each draggable element
2. Added the nodeRef prop to each Draggable component to avoid using findDOMNode
3. Properly typed the event handlers to avoid TypeScript errors
4. Added ref cleanup when removing items to prevent memory leaks

How it works:

1. For each draggable widget in the left panel, we create and maintain a ref
2. For each dropped widget in the main panel, we also create and maintain a ref
3. These refs are passed to the Draggable components via the nodeRef prop
4. This tells react-draggable to use the ref directly instead of calling findDOMNode

This approach maintains all the functionality of the original implementation while fixing the error related to the deprecated findDOMNode API.

Make sure you're using the latest version of react-draggable:

This solution should work with React 18+ while still using the react-draggable library as requested.

I'll update the code to use react-grid-layout for resizing elements and add a side panel for editing element properties.

I've completely revamped the code to use react-grid-layout for resizing elements and added a property panel for editing widget properties. This implementation keeps react-draggable v2 for the left panel while using react-grid-layout for the main content area.

Key Features:

1. Left Panel: Uses react-draggable v2 for dragging widgets to the drop zone
2. Main Panel: Uses react-grid-layout for a responsive, resizable grid layout
3. Property Panel: Appears when a widget is selected, with custom editors for each widget type
4. Live Updates: Widgets update in real-time as properties are changed

How to Install Required Packages:

How It Works:

1. Drag & Drop: Drag widgets from the left panel to the main area
2. Resize & Reposition: Use react-grid-layout to resize and reposition widgets
3. Edit Properties: Click on a widget to select it and edit its properties in the side panel
4. Live Preview: See changes immediately as you edit properties

Widget Types and Properties:

1. Text Widget: Edit content, font size, and color
2. Image Widget: Set image URL, alt text, and aspect ratio
3. Chart Widget: Configure chart type, data, labels, and title
4. Layout Widget: Set number of columns and gap size
5. Comment Widget: Edit content, author, and timestamp

This implementation provides a complete drag-and-drop interface with resizable widgets and a property editor panel, all while maintaining compatibility with react-draggable v2.
