I am developing my own lookup field.

I want it to have dynamically filtered values collection depends on user which makes new item.

What method of lookupfield class I should override to make my own collection of values to send on client to render there?

I need send from server to client side additional info about items in related lookup list as well.

And all this I really need to do on server side.

Multiple solutions all about client side... REST CSOM JSLINK CSR..

Any advice please about server.
