I want to produce a title element for a shell that will not be scrolled out of screen when the user scrolls down.
an example can be found in facebook widset, and in the "Library" located on the dashboard.
I already tried using a flow that contains flow(for title) and scrollable with flow in it(for the content of the window), but it doesnt work well, at least no as I see that it works for facebook widset.

any ideas?
