Create solution for simultaneous editing of html-fields

I need a solution for real time editing of html-fields by multiple users over network. The content should be synced in real time so everyone is up to speed. The solution needs to handle multiple fields being edited on the same page with multiple users. If not too much work it would be nice to see other users cursors with name, to know who is editing where. This will be much like google docs, but for html fields (input and textarea). What I need is the javascript library/code for this, so I can use it in my system. It needs to use clean javascript with jQuery on the client. The server should use nodejs for processing if needed. The system should handle multiple users editing the same field simultaneous using for example CRDT. The connection to clients is done with rabbitMQ. This system is already established, so what I need is just the data to send and that the code can handle receiving it. I will handle the communication.
