That's a different framework! > Question: > Where and how I can enter this code Fx.Slide.Options.direction? I don't believe this is possible with Moo's Slide. The principal concern with most effects is that they insert new elements into the DOM, -- either wrapping, wrapped by, or replacing your elemetns -- and if your markup and styles are the slightest bit "fancy," that fanciness is likely to go away when you apply the effect unless the effect itself offers an equivalent. The "fancy" thing you want here is an element anchored to the bottom of its container (like pos: abs; bottom: 0;), so that when its height changes, it draws "up." It's easy to do with CSS alone -- but not such that it won't get mangled by applying a prefab effect. Stratboy's hack here is along the same lines, but you may not be comfortable with this much code: http://groups.google.com/group/mootools-users/browse_thread/thread/e899402564653a55?pli=1 Every framework has its own standard set of effects, but you may also find a third-party Mootools class that does this for you. -- S.
