Thanks Vaibhav for your quick response. I've figured out the way to achieve the functionality. FYI, you can create custom nodes and register the names with ReactFlow component and use the same name as the node type to be able to save and restore custom components. You can refer this link to get a clearer picture of what I was talking about - reactflow.dev/examples/custom-node/
Look out for ColorSelectorNode.js and setElements() function usage

actually for automatic position requires the dagre library from npm, for details you can see in the documentation reactflow.dev/examples/layouting/

sorry for my bad english

Thanks for reading!

Not sure of the image support but you can read here that:

Drag and Drop sidebar handling is not built in but can be implemented with the native HTML Drag and Drop API
