It seems like it implies the viewport context related to “remove from viewport” has been taken out along with everything that uses it. I’m on 4.6.1 and “Add to viewport” just doesn’t exist in the context menu.
To check I just opened a blank project (4.6.1) and created a Widget Blueprint… right-clicked the graph and searched and found it. Perhaps you’re trying to drag and create it from the wrong node?
Edit: In the Level BP I’ll only see the node if I de-select ‘context sensitive’, so it probably is about pulling from the right node to get it.
Initially nothing relevant would node out from “Create menu_c widget”. I tried setting it up like the docs again and this time it worked. I guess I just missed something the first time. Thanks guys!
