Dropdown Mode
When  dropdown  mode  is  enabled,  a  dropdown  button  is  displayed  next  to  the  input  field.
Depending on dropdownMode configuration, clicking this button will either do a search with an
empty query or search with the current value in input.
<p:autoComplete value="#{bean.text}" completeMethod="#{bean.complete}"
dropdown="true" />
Multiple Selection
AutoComplete supports multiple selection as well, to use this feature set multiple option to true and
define a list as your  backend  model. Following  example  demonstrates  multiple  selection with
custom content support.
<p:autoComplete id="advanced" value="#{autoCompleteBean.selectedPlayers}" 
completeMethod="#{autoCompleteBean.completePlayer}"
var="p" itemLabel="#{p.name}" itemValue="#{p}" converter="player"
multiple="true">

Caching
Suggestions can be cached on client side so that the same query does not do a request which is
likely to return same suggestions again. To enable this, set cache option to true. There is also a
cacheTimeout option to configure how long it takes to clear a cache automatically.
<p:autoComplete value="#{bean.text}" completeMethod="#{bean.complete}"
cache="true"/>
Ajax Behavior Events
Instead of waiting for user to submit the form manually to process the selected item, you can enable
instant ajax selection by using the itemSelect ajax behavior. Example below demonstrates how to
display a message about the selected item instantly.
<p:autoComplete value="#{bean.text}" completeMethod="#{bean.complete}">
<p:ajax event="itemSelect" listener="bean.handleSelect" update="msg" />
</p:autoComplete>
<p:messages id=”msg” />
public class Bean {
public void handleSelect(SelectEvent event) {
Object item = event.getObject();
FacesMessage msg = new FacesMessage("Selected", "Item:" + item);
}
//...
}
Your listener(if defined) will be invoked with an org.primefaces.event.Select instance that contains a
reference to the selected item. Note that autoComplete also supports events inherited from regular 
input text such as blur, focus, mouseover in addition to itemSelect. Similarly, itemUnselect event is 
provided for multiple autocomplete when an item is removed by clicking the remove icon. In this 
case org.primefaces.event.Unselect instance is passed to a listener if defined.

<p:barcode value="#{bean.barcodeValue}" type="int2of5" />
Format
Default display format is svg and other possible option is png. In case the client browser does not
support svg e.g. IE8, barcode automatically chooses png format.

by qrgen library. Following versions are supported officially.

Getting Started with BlockUI
BlockUI requires trigger and block attributes to be defined. With the special ajax integration, ajax
requests whose source are the trigger components will block the ui onstart and unblock oncomplete.
Example below blocks the ui of the panel when saveBtn is clicked and unblock when ajax response
is received.
<p:panel id="pnl" header="My Panel">
//content
<p:commandButton id="saveBtn" value="Save" />
</p:panel>
<p:blockUI block="pnl" trigger="saveBtn" />
Multiple triggers are defined as a comma separated list.
<p:blockUI block="pnl" trigger="saveBtn,deleteBtn,updateBtn" />
Custom Content
In order to display custom content like a loading text and animation, place the content inside the 
blockUI.
<p:dataTable id="dataTable" var="car" value="#{tableBean.cars}"
paginator="true" rows="10">
<p:column>
<f:facet name="header">
<h:outputText value="Model" />
</f:facet>
<h:outputText value="#{car.model}" />
