I am trying to have a 5 tab application where a menu slides from the left to reveal additional options and a search/filter menu that slides from the bottom. Currently, the SfNavigationDrawer only supports a view as the ContentView (whatever is shown when the menu is hidden). I've seen the sample of the SfNavigationDrawer within a TabbedPage, however, that's not what I want, as I want the menu to cover everything including the tabs, and I want both menus to be consistent between all tabs. Is there any way to do this? Many thanks in advance.
