A page is the basic building block of an application. When you build an application in App Builder, you create pages that contain user interface elements, such as tabs, lists, buttons, items, and regions.
Tip:
You view and manage application pages in App Builder using either Page Designer or Component view. To learn more, see "Managing Pages in Page Designer" or "Managing Application Legacy Components."

Developers add pages to an existing database application by running the Create Page Wizard. You can access this wizard as follows:
On Application home page — Click Create Page. See "Creating a Page from the Application Home Page."
Viewing a page in Page Designer — Click Create on the Page Designer Developer toolbar and select Page. See "Page Designer Toolbar"
Viewing a page in Component View — Click Create on the Component View navigation bar and select Page. See "Component View Navigation Bar."
When you create an application, you choose a target user interface. The user interface you select determines the available page types. Not all page types are supported by all user interfaces.
Available Page Types for Desktop Applications

To create a page from the Application home page:
Oracle Application Express includes support for dialog pages. Modal and non-modal dialog pages are only supported if the current application theme contains at least one page template of template type Dialog Page.
Topics:
When you create a new page, the wizard prompts you to select a Page Mode. The Page Mode determines if the page is a normal application page or a dialog page. Oracle Application Express supports two types of dialog pages:
Modal Dialog - A modal dialog is an overlay window positioned within the within the same browser window. A modal dialog remains active and focused until the user has finished with it and closes it. While a modal dialog is active, the user is unable to interact with the rest of the page until the dialog is closed.
Non-modal Dialog - A non-modal dialog displays a separate popup browser window. A user can interact with a non-modal dialog and content on the page. Use a non-modal dialog when the requested information is not essential to continue. This type of window can be left open while work continues elsewhere.
Oracle Application Express includes dialog page templates in the Universal Theme - 42. When you set the Page Mode to either Modal or Non-Modal, Oracle Application Express automatically uses the default dialog page template. This section describes how to create a dialog template if your theme does not include one and how to edit dialog template attributes.
If you are using an existing application and the theme does not contain such a dialog page template, then you must create one. While you can create one from scratch, the easiest option is to copy an existing dialog template.
To create a dialog page template:
Copy the dialog page template from the Sample Database application:
On the Workspace home page, click the App Builder icon.
Select the application to which you want to copy the template.
Click Shared Components.
Under User Interface, select Templates.
Click Create.
In the Create Template Wizard:
Template Type - Select Page and click Next.
Creation Method - Select As a Copy of an Existing Template and click Next.
Copy From - Select Sample Database Application and click Next.
Identify Theme - Select the theme you are copying from and the theme you are copying to and click Next.
New Template - Locate the Modal Dialog template. Under Copy, select Yes.
Select Create Copy Page Templates.
Verify the dialog page template is active in the current theme. See "Selecting a Default Page Template."
The dialog page template contains JavaScript function calls that handle the initialization, closure, and cancellation of a dialog page. When you create a dialog page template you must define these and other Dialog Page Templates attributes.
See Also:
To create a dialog page you must set the Page Mode to either Modal Dialog or Non-modal Dialog. You can configure the page mode when running the Create Page Wizard or by editing the page attributes.
To define a page as a dialog in Component View:

To define a page as a dialog in Page Designer:
See Also:
If your dialog page contains a Cancel button, then you must generate a dynamic action based upon the Click of that button, with its True Action event being set to Cancel Dialog. This dynamic action will use the cancellation JavaScript call contained in the page template (apex.navigation.dialog.cancel
) to handle the cancelling the dialog.
See Also:
You close a dialog page in Oracle Application Express by creating a Close Dialog page process. In previous releases, this page process was referred to as a Close Popup Window
. This dialog will use the closure JavaScript call contained in the page template (apex.navigation.dialog.close)
, to handle the closing of the dialog. The page process also supports the return of dialog page items, which you may wish to reference on the parent page. To view examples, edit any of the Dialog pages in the Sample Database Application.
Tip:
You can also close a dialog page with the Close Dialog dynamic action. Both the dynamic action and the process support returning dialog page items. Use the page process when the page needs to be submitted and use the dynamic action when the page does not need to be submitted. Both end up calling the closure JavaScript call. Alternatively, you can create a page branch, which will close a dialog page and redirect to the page specified in the branch.
You can open dialog pages using buttons or links. Dialog pages support the following branching options:
Dialog page to dialog page.
You can branch from one dialog page to another dialog page if:
Both pages have the same Page Mode, for example Modal Dialog and the dialog Chained attribute is set to Yes. Setting the Chained attribute to Yes enables support for chained or nested dialogs such as the dialogs that appear many internal Application Express wizards. Chained or nested dialogs enable you to re-use a dialog window to display each page.
Dialog page to Normal page.
When branching from a dialog page to a normal page, the dialog page is closed and the user navigates to a new page in the browser. The new page can be parent (or launching) page or another Normal page in an application.
If you have generated a Close Dialog page process on the dialog page, you must implement refresh actions on the parent page using the new Dialog Closed
dynamic action event type. You can use the set type Dialog Return Item when creating a Set Value True Action, to set a single value, based on the return item of a dialog.
To see an example, go to the Products page in the Sample Database Application. On the Products page, the Create Product button has an associated dynamic action that launches the dialog. Closing the dialog triggers the Dialog Closed
dynamic action. You can use this type of dynamic action for whatever True Actions you wish to define. In this example, it refreshes the report on the parent page and submits the page.
Tip:
For a partial page refresh of a parent page, implement the close dialog with dynamic action (for example, for report and form pages where you want to edit data in a modal dialog form and only want the report refreshed on close). In contrast, branching is the best approach if you have a multi step modal wizard or if you have several possible target pages when closing the dialog.
You can copy a page from the current application or from another application. During the copy process, you can also copy shared components or change mappings to shared components in the target application.
Note:
Oracle does not support copying Desktop pages to jQuery Mobile Smartphone pages or copying jQuery Mobile Smartphone pages to Desktop pages.
The Copy Page Wizard enables you to copy a page to a different user interface. During the copying process, the user can select the user interface for the new page. If the application contains a Desktop and a Mobile theme, both user interface options display.
Oracle does not support copying Desktop pages to jQuery Mobile Smartphone pages or copying jQuery Mobile Smartphone pages to Desktop pages. Attempting to copy the following Desktop pages to a Mobile user interface results in an error:
Interactive report
Flash map
Flash chart
Tree region
Deleting a page deletes the corresponding tabs, breadcrumbs, and list entries. You can only delete unlocked pages or pages that you have locked.
