Using only Win32 C++ (no WTL or MFC or any other third-party library), how can I get custom menu borders?

I was able to ownerdrawn the items but the borders are in the Non Client area and I was unable to find a way change them.

Is there a way?

            ::OffsetRect(&rect, -rect.left, -rect.top);
            int border = 1;
            rect.left = rect.left + border;
            rect.top = rect.top + border;
            rect.bottom = rect.bottom - border;
            rect.right = rect.right - border;
            HBRUSH bg = CreateSolidBrush(RGB(255,0,0));
            //Rectangle(menuDc, rect.left, rect.top, rect.right, rect.bottom);
            int borderThiness = 3;
            ::ExcludeClipRect(menuDc, rect.left+ borderThiness, rect.top+ borderThiness, rect.right- borderThiness, rect.bottom- borderThiness);

            DeleteObject(bg);
            isInitPopup = false;
