ChoiceGroup works very similar to List. However, The ChoiceGroup is indented to place on a form object and the actions can be performed when the its items are selected. The prototype to create a choice group object is:
ChoiceGroup choiceObj=new ChoiceGroup(Title,Type);
The Title argument is used to specify the title of the choice group. The second argument is the type of the choice group. The values of the type can be Choice.EXCLUSIVE, Choice.IMPLICIT, Choice.MULTIPLE, Choice.POPUP, Choice.TEXT_WRAP_DEFAULT, Choice.TEXT_WRAP_OFF, and Choice.TEXT_WRAP_ON.
The element can be added to the choice group by using append method of its object.
Note: In this example, we provide two ways to perform actions on the lst choice group. One way is using CommandListerner interface and another is ItemStateListener interface. By using the latter, the actions are performed when the item of the lst choice group is selected. You need to write code for the ItemStateChanged() method to generate the actions.
