The portal page is made up of sections:
Top Bar |
|
The Top Bar includes the Search box, Log In/Log Off link and help link. Some elements of the Top Bar can be customized by changing style sheets and modifying the associated strings in the portal language files. You can design a completely new Top Bar using Adaptive Tags and a custom portlet.

Header and Footer |
|
The Header includes branding information for the portal and can also be used to display content.

The Footer provides additional content and can be customized to include additional functionality. These sections of the portal page can be customized using ALI Publisher portlets. For details, see the ALI Publisher online help.

Navigation |
|
The Navigation section of the page provides access to the different sections of the portal and the current Community. The portal comes with a selection of built-in navigation schemes. Custom navigations can be built easily using Adaptive Tags. Advanced navigation customizations can be implemented using the portal navigation framework.

Banner |
|
The Banner includes the Top Bar, Header, and Navigation sections of the page. The entire Banner can be easily customized by disabling the Navigation and Top Bar sections and using a header portlet with Adaptive Tags to display all banner content.
Body |
|
The Body is the main section of the portal page, and displays the portlets selected for the page. The Body section can be split into multiple panes in a variety of layouts, configured in the My Page or Community Editor. (For instructions, see the portal online help.) You can also create custom page layouts using View replacement.

Portlets are the building blocks for portal pages, providing specific content and services. Each portal page is made up of multiple portlets with a range of functionality. The AquaLogic Interaction Development Kit (IDK) provides a wide range of tools for creating dynamic portlets that plug in to the portal.

For very advanced customizations to the layout of the portal page, you can use View replacement (not recommended for most customizations).
For an introduction to how the portal works, see the Overview of AquaLogic Interaction. For a full listing of development topics, see the table of contents.
