Smartmenu implementation using offsetY to displace popup such that the previous selected item will fall onto cursor, includes checked item and highlighted. For `Popup Menu` in theapartment, without this patch the second popmenu was not remembering the last selected item and was opening it from scratch, after this patch popupmenu will open from the last selected item already selected with checkbox.
