The Catalog pane, shown in Figure 13.8, displays information about available catalogs, including the customized catalogs you create or import. Click the hierarchical control next to a catalog to expand it and view its contents. Click the control again to collapse the view. Alternatively, double-click an item to expand or collapse its view in the Catalog pane.

You can create customized catalogs to store the components you use most frequently. These customized catalogs make it easier for you to build your application's layouts. To learn how to create your own catalogs, see "Creating Component Catalogs".
