OK, thank you.
I just needed to get further ahead with things over the past two weeks which is why I reverted to just the plain bootstrap menu, but I will look to incorporate SmartMenus again on the above basis.
I was later fiddling around with using just pure css for the menu at that previous link but the new dev area is now here http://mybusiness-mylife.com/bootstrap-fresh/
I have got over the problem with the toggle menu, but the sub menus are still right aligned to the main menu where, although I want the menu itself right aligned, I would still like the sub menus aligned with the beginning (left) edge of the main menu rather than the end (right) edge.
Is there still a way to fix this?
Thanks again.
