8.4 Additional Page Flow Features

In addition to getting rendered and submitted, APEX pages also uses background data requests and support redirects to navigate without submitting data. Breadcrumbs help visualize the navigation path of drill down page flows. Modal dialogs offer an alternative to present related information without losing the context of the calling page.

• Understanding AJAX and Redirect
  In addition to the page render and submit interactions with the APEX engine, your page can also run business logic on the server and refresh regions to show the latest data without re-rendering the entire page.
• Breadcrumbs Visualize Drilldown Path
  Users often drill down from a list row to view or edit details. If that page shows related records, they can keep following those relationships. Breadcrumbs show their place in the flow and let them return to higher levels.
• Modal Dialogs and Drawers
  A modal dialog appears centered above the page that opens it. By default, it sizes to its content, but you can set its width and height or make it fill the available space. Configured as a drawer, it slides in from the start or end edge.
