    HierarchyExt.layout.LayoutExt.layout.container.AbstractContainerExt.layout.container.ContainerExt.layout.container.AbstractFitExt.layout.container.FitExt.layout.container.AbstractCard

This layout manages multiple child Components, each is fit to the Container, where only a single child Component can be visible at any given time. This layout style is most commonly used for wizards, tab implementations, etc. This class is intended to be extended or created via the layout:'card' Ext.container.Container.layout config, and should generally not need to be created directly via the new keyword.

The CardLayout's focal method is setActiveItem. Since only one panel is displayed at a time, the only way to move from one Component to the next is by calling setActiveItem, passing the id or index of the next panel to display. The layout itself does not provide a user interface for handling this navigation, so that functionality must be provided by the developer.

Containers that are configured with a card layout will have a method setActiveItem dynamically added to it.

          var p = new Ext.panel.Panel({
              fullscreen: true,
              layout: 'card',
              items: [{
                  html: 'Card 1'
              },{
                  html: 'Card 2'
              }]
          });
          p.setActiveItem(1);

True to render each contained item at the time it becomes active, false to render all contained items as soon as the layout is rendered (defaults to false). If there is a significant amount of content or a lot of heavy controls being rendered into panels that are not displayed by default, setting this to true might improve performance.
