The new Codrops multi-level push menu is awesome and is honestly exactly what I need for a project I have right now; the problem is that it doesn't work in Internet Explorer 9, which I have to support.
The animations (beyond the initial push effect of course) are all nice-to-haves, but not necessary for me; what I really need is the nested menus, because the menu structure I'm developing will turn out to be rather deep.
As it's for a Javascript application, that requirement is a nonissue. What really matters is getting it to work in Internet Explorer 9, which doesn't support Transforms; so how do I pull this off?
