This chapter described MIDP's advanced user-interface screens, List and Form. A List is a list of elements that allows for single or multiple selections. You supply the items-it's up to the implementation to figure out how to show them, how the user navigates through them, and how the user selects items. Forms are generalized screens that are built up from a collection of Items. The MIDP API supplies a handy toolbox of Items-everything from simple string and image Items to the more complex DateField and ChoiceGroup.

Even though List and Form are very capable, you should use them sparingly, particularly Form. Small devices have small screens, so you don't want to put much information in each screen, especially if it's going to force the user to scroll up and down a lot. Furthermore, ease of use is crucial on consumer devices like mobile phones and pagers. Make sure your interface is clean, intuitive, and as simple as it can possibly be.
