It also includes creating custom components and PrimeFaces Extensions.You will start with the basic concepts such as installing PrimeFaces, configuring it, and writing a first simple page. You will learn PrimeFaces' theming concept and common inputs and selects components. After that more advanced components and use cases will be discussed. The topics covered are grouping content with panels, data iteration components, endless menu variations, working with files and images, using drag & drop, creating charts, and maps.

Displaying overflowed content with scrollPanel


The scollPanel component provides customizable scroll bars instead of the browser's scrolls.

How to do it...

A basic definition for a scroll panel with a width of 500 pixels and a height of 500 pixels would be as follows:

<p:scrollPanel style="width:500px;height:500px">
  <p:dataGrid var="car" value="#{scrollPanelController.cars}" 
  columns="2">
    <p:panel header="#{car.name}" style="text-align:center">
      <p:graphicImage value=
      "/resources/images/autocomplete/#{car.name}.png" />
    </p:panel>
  </p:dataGrid>
</p:scrollPanel>

This will render a list of car models within a data grid. The visual size of the grid will be limited to a 500 by 500 pixels view, and the content can be scrollable horizontally and vertically. By default, customized scrollbars will be rendered as shown in the following screenshot:
