"PrimeFaces Cookbook" covers over 100 effective recipes for PrimeFaces 3.x which is a leading component suite to boost JSF applications. The book's range is wide‚Äí from AJAX basics, theming, and input components to advanced usage of datatable, menus, drag & drop, and charts. 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. The last chapters describe solutions for frequent, advanced scenarios and give answers on how to write custom components based on PrimeFaces and also show the community-driven open source project PrimeFaces Extension in action.

MegaMenu – multicolumn menu

A mega menu, sometimes also called a mega drop-down menu, is designed to enhance scannability and categorization of its contents. PrimeFaces' mega menu is a horizontal navigation component that displays menu items grouped in submenus. The main advantage of such a kind of menu is that everything is visible at once—no scrolling is required.

In this recipe, we will design and implement a mega menu for an imaginary online shop selling clothes.

How to do it...

The layout of the MegaMenu component is grid-based. That means, root items require columns as children to define each section in a grid. Root items are direct submenus below p:megaMenu.

We will design four root items. The first one will show women's clothing, the second one will show men's clothing, the third one will show a color guide (pictures with available clothing colors), and the last one will show the shopping cart in a dialog.

<p:megaMenu>
