A view cannot reference a form/document, except ShowSingleCategory if it is embedded in that form/document. Obviously, a form/document can reference other docs via @Db, but your view column formulas still aren’t going to want to reference any of that information.
I’m not sure that I understand your question, so I will answer the question I think that you are asking. First the view selection formula is irrelavent as it will work the same way if it is in a frame or not. However, you could use a single category if that meets your purpose. Secondly, if you want to select a document in the view and have it display in the related form then in the Frame Properties of the view set the Target where you want the link (document) to display.
I have a 3 frame set where the first frame is a navigator that displays the various views that are available. Selecting a view from the Navigator displays the actual view in the second frame. Then selecting a document from the view displays it in the third frame that displays the document in the proper form.
It took a little experimentation but it works real well.
Hope this answers your question, if not perhaps you can give a little more detail.
