Rolling your own Cascading menu's in IOS?

[FireWorx]

Any one have any luck building cascading menus in IOS. I worked on it yesterday for a couple hours and then put it on the back burner. I was using the commands "mousewithin", "mouseenter", "mouseleave", "the control", etc but nothing really worked that well.

I can see on the iPhone sticking with the traditional list interface and flipping through cards with the back,forward, and select buttons as navigators but on the IPAD where you have more real estate it doesn't make sense to me.

I Settled for crafting radio buttons and showing and hiding groups with the other choices. It works but in my opinion it is not as slick as a cascading menu. my users need to select 1) an FD Agency, 2) a letter and 3) a two digit number for a final outcome of FD #1 - T34 or FD #3 - V19 etc. I don't want to use the IOS keyboard it's too big and clunky and switching between the numbers and the letter keyboard is lame. I know there is keyboard short cuts but I don't want my users to have to learn them. The user will be on the road in a bumpy truck hauling to an emergency with sirens and talking on the radio etc and I don't want to make them type.

I would like to cascade it something like this.


FD 1
FD 2 U
FD 3 V 33
FD 4 X 34
......Y 35
......Z 36 Dave

Take a look at the iphonePick command. It may let you do something similar without having to roll your own solution.
