Add text to f:selectItems label in XHTML

Question

Am trying to add to add text to itemLabel.

<p:selectOneMenu id="firstRemindDaysBefore"  
                 value="#{vehicleController.vehicle.DaysBefore}"
                 valueChangeListener="#{vehicleController.reminderBeforeDays}">
       <f:selectItem itemLabel="Select One"/>
       <f:selectItems value="#{vehicleController.lstRemindDaysBefore}"
                      itemLabel="#{vehicleController.lstRemindDaysBefore} Days"/>
</p:selectOneMenu>

I have tried like this but not getting reflected.

itemLabel="#{vehicleController.lstRemindDaysBefore} Days"

How to solve this?

Answer 1

I suppose that:

vehicleController.lstRemindDaysBefore

is a List of some Day Objects, if I'm right than the code should look more or less like this:

<p:selectOneMenu id="firstRemindDaysBefore"  
             value="#{vehicleController.vehicle.DaysBefore}"
             valueChangeListener="#{vehicleController.reminderBeforeDays}">
   <f:selectItem itemLabel="Select One" itemValue="#{null}" />
   <f:selectItems value="#{vehicleController.lstRemindDaysBefore}" var="day"
                  itemLabel="#{day.label} Days" itemValue="#{day}" />
</p:selectOneMenu> 

or if it is a List of Integers then:

<f:selectItems value="#{vehicleController.lstRemindDaysBefore}" var="day"
                  itemLabel="#{day} Days" itemValue="#{day}"/>
