I know, and I've tried a bunch of them. Either unstable or too basic (or both) or Flash-based. I still use MM, but submenus will not work on iPad or iPhone.
Will eventually have to fix that problem, and hope that someone will come on board with as good a product.
I still use MM on several sites. The dropdown menus work pretty well on iphone and ipad for me. Check out www.ronaldsachs.com.
I have mixed results with the pull outs. Check out www.starmilling.com
...and yes, iOS friendly too.
Here is one option: http://css3menu.com
And Google leads to many more.
I've tried most of these, and none are as customizable or as easy to use as MM.
Hoping someone will come up with a good alternative, but I haven't seen it. Spent 5 times the cost of MM paying for these others.
I'm not following your logic on paying for free software that generates CSS that can be fully customized in GoLive.
Because all those CSS menu makers are terrible to use. MenuMachine was by far the best and easiest way to build awesome menus.
