Please help me find the solution.

I need create some sort of filter on content proposal. The code completion proposal should include keys that are already defined in the current document as non-active options (i.e. cannot click/add them; "greyed out"; at the end of the list). It would be a nice to see some code example.

Thanks.

Depends on the kind of elements. Is this about cross references ?) about
keywords ? ..

you can override completeKeyword in the proposal provider. https://kthoms.wordpress.com/2012/05/22/xtext-content-assist-filtering-keyword-proposals/ (should more or less still work)
