I think there's no primefaces component to achieve this but you can use plain jsf.

Try <h:selectManyMenu> or <h:selectManyListbox>.

Here is an example for the menu:

<h:selectManyMenu
    id="newsletters"
    value="#{bean.selectedItems}">
    <f:selectItems
        value="#{bean.availableItems}"/>
</h:selectManyMenu>

You'll find more information in the Java EE tutorial.

Primefaces 3.0 M1 has a SelectManyMenu component. You can download 3.0 M1 version here

2.2.1 doesn't have such component. Regards.
