Introducing SelectOneListbox

The SelectOneListbox component is an extended version of the standard SelectOneListbox component with theme integration. Basic usage of <p:selectOneListbox> is as follows:

<p:selectOneListbox value="#{selectionController.number}">
    <f:selectItem itemLabel="One" itemValue="1" />
    <f:selectItem itemLabel="Two" itemValue="2" />
    <f:selectItem itemLabel="Three" itemValue="3" />
</p:selectOneListbox>

The preceding <p:selectOneListbox> component will be rendered as shown in the following screenshot:

We can also use POJOs to populate <p:selectOneListbox> options. Let us see how to populate SelectOneListbox using POJOs.
