Autocomplete

[Guido1982]

I created this branch as a testcase for autocompletion. This works in detailview, but I can't get something similar in createview, because it is much harder to get the related module name of the UI 10 field there. I'd like to discuss a roadmap to edit the core, so that we can add a class or a 'data-' field (or both) to the input fields, in order to create a robust autocomplete mechanism for these fields. Is that something we could do?
