Grid inside a Form

Greetings Comrades,
I have a form where you want to display two lists between which items I want to spend.
The idea is that the user selects a set of words in a list and locate in another list.
If anyone has a code sample or something, I would greatly appreciate! =D> =D> =D>

Which framework are you using?

How does what you want differ from this?

Thanks so much. sorry i didn't look at the examples.

If you would like to associate a model to itemselector, so that the right items on the list are those that are saved as would be the implementation. That would be my great doubt.
