The selectOneMenu component is an extended version of JSF selectOneMenu. It provides custom content display along with skinning capabilities.
The simplest component declaration would be as follows:
<p:selectOneMenu> <f:selectItem itemLabel="English" itemValue="en"/> <f:selectItem itemLabel="Turkish" itemValue="tr"/> </p:selectOneMenu>

Instead of working with primitive types or just string literals, most of the time we would be using the selectOneMenu component with domain objects. The basic definition of the component for listing the cars for a given brand would be as follows:
<p:selectOneMenu id="carPOJO"
value="#{selectOneMenuBean.selectedCar}" var="car">
<f:converter
converterId="org.primefaces.cookbook.converter.CarConverter" />
<f:selectItems value="#{selectOneMenuBean.cars}" var="c"
itemLabel="#{c.name}" itemValue="#{c}" />...
