I want is a go from a menu that has a list of objects, if you select an option menu another list should appear.
The examples I found seemed to be for listview or webview.
There another way to make a selection from menu options?

So if I'm understanding your right, you want to launch a Context Menu from an Options Menu. You should not do this. From the android documentation:
A context menu is conceptually similar to the menu displayed when the user performs a "right-click" on a PC. You should use a context menu to provide the user access to actions that pertain to a specific item in the user interface. On Android, a context menu is displayed when the user performs a "long press" (press and hold) on an item.
You'd never do a "long press" on an Options Menu item. People just aren't used to doing that.
Try launching another activity instead or using a dialog.

If you have a fixed list of options in mind you might be looking for submenus, which are explained here: http://developer.android.com/guide/topics/ui/menus.html
If you are looking to dynamically build a list of options with an adapter you might find AlertDialog.Builder useful along with its setAdapter method.
