What do you mean by text fields. The xtext web integration gives you an editor

Need professional support for Xtext, Xpand, EMF?

Yes, I have been using the editor, specifically the web editor. It is great so far, but my use case is as follows
For example
Greeting:
'Hello' name=ID '!';

when the interpreter reaches the name; I would like to provide the user a list of options with content assist, by doing a dynamic look up
I am currently looking at the class AbstractMyDslProposalProvider is that the correct one to extend so I can extend the content assist for the web editor?

ok, I think I figured that I need to follow
https://www.eclipse.org/Xtext/documentation/330_web_support.html#content-assist

My previous post modifies the content assist within Eclipse Editor, not Web Editor
