Matteo over at Cubiq has created a nifty spinning wheel selector widget and released it under the MIT License. The widget gives you the ability to present users with a picklist with multiple columns, with animation that closely resembles the native Picker View.
SpinningWheel object is unique and it is created as soon as you include the JS file.
Customizing the slots is simple, just add your own styles. The whole thing has been minified to 9kb, so it’s using minimal bandwidth.
Matteo was kind enough to make a nice screencast for you to enjoy on your desktop. You can also see a working demo on your iPhone/iPod Touch here.
