Annotation in SEGW

[BODHISATTWA__20]

I have created a SEGW service  . I have enabled the filter options so that when i consume it in VS so that I automatically get those fields as filter parameters  .

But 

I have some CDS views which are also part of the same OData .I want them to be a value help on the same those filter parameter  .

I looked into  this blog  https://community.sap.com/t5/technology-blogs-by-members/odata-annotations-in-segw-with-example-and-...

.Instead of this fixed values , I want the CDS to be displayed  or a table .

can anybody tell me what would be the right annotation for this .
