    No PrimeFaces component comes to mind, but how about just this?

    <h:form>
        <ul>
            <ui:repeat value="#{bean.list}" var="item" varStatus="loop">
                <ui:fragment rendered="#{loop.index lt 6 or bean.showAll}">
                    <li>#{item}</li>
                </ui:fragment>
            </ui:repeat>
        </ul>
        <h:commandButton value="Show all" action="#{bean.setShowAll(true)}" rendered="#{!bean.showAll}">
            <f:ajax render="@form" />
        </h:commandButton>
    </h:form>
    

    with

    @ManagedBean
    @ViewScoped
    public class Bean implements Serializable {
    
        private List<String> list = Arrays.asList("one", "two", "three", "four", "five", "six", "seven", "eight", "nine", "ten");
        private boolean showAll;
    
        public List<String> getList() {
            return list;
        }
    
        public boolean isShowAll() {
            return showAll;
        }
    
        public void setShowAll(boolean showAll) {
            this.showAll = showAll;
        }
    
    }
    

    You could wrap it if necessary in a composite.
