The Page Builder is a tool in AppBase for designing pages to use in your application. Using drag-and-drop and wizards, you can design complex pages and modify the page's markup if needed. 

When entering the Page Builder, the page looks very similar to this:

Data Sources tab

The Data Source tab holds all the data sources that interact with your page. To add a data source, click on the arrow on the Add button. To edit a data source, select it and click on Settings in the Properties panel. Data Sources allow your page to interact with other data, like business objects and other pages.

Sections tab

The Sections tab is a good place from which to navigate among the various panels within your page. Clicking on a panel will make its components appear on the Design surface.

DOM tab

All new pages come pre-populated with the following four components
