Theme Cosmos - Customizing Section-based Portals in App Studio
This article has been moved over to our Pega Community here in order to align with our larger content strategy. Please update any bookmarks or links that you may have to this location.

When building a Pega Platform application on section-based Theme Cosmos, the default portal is the user portal. However, citizen developers can create new portals from the Channels area of App Studio. Once the basic portal is built, there might be a need to customize it based on specific needs. For example, certain users might only need to work on tasks assigned to them, while others need to access work queues and pick up tasks from a common pool. Yet another set of users might require customized landing pages that give them access to data beyond the scope of the out-of-the-box user portal.

Users might also want to specialize their dashboards to have easy access to the data that they use most frequently. Apart from customizing the portal, citizen developers might want to customize specific details within a case to improve productivity.

Note that the screenshots used in this article might vary based on platform versions.

Customizing the worklist gadget

By default, the Home page in the user portal contains the My worklist gadget that allows users to pick up tasks assigned to them. In some cases, tasks are not assigned to specific users, but to work queues. In this way, any user with access to the work queue can pick up the task and work on it.

The following steps help you modify the worklist gadget to allow picking tasks from work queues in addition to tasks assigned to oneself.

1)    Log in to App Studio and click the Preview button in the top right corner. A Design icon appears.

2)    Click the Design icon to enter the Design mode.

3)    Click the Pencil icon next to the main section to enter edit mode.

The editing pane is on the right side of the screen.

4)    Click the Edit this section pencil icon next to HomeWorklist section.

Pencil icon is on the right side of the component name.

5)    Click the Settings link in the pane that opens.

The settings link is in the top-right of the editing pane.

6)    Notice two options as shown in the screenshot below. Click the checkbox next to Show team assignments in worklist to allow the user to pick assignments from work queues to which they have access. Click the Apply button on the top-right side and close the Edit pane.

7)    By default, the user portal displays the worklist gadget as a repeating layout, as shown in first screenshot below. If you select the Display worklist as a table check box in step 6, the system converts the display into a table as shown in the screenshot below. You can choose the option you prefer.

Customizing landing pages in the main menu

The user portal consists of landing pages that consolidate information for easy access. The landing pages are listed on the main menu. The default landing pages are: Create, Home, Dashboard, Spaces, Reports and Explore Data. If you want to add or remove certain landing pages from the main menu, follow the steps below.

1)    In App Studio, click Preview, and then click Design on the top-left side of the portal to enter Design mode.

2)    Click Pages on the top-left side of the Portal.

3)    Click New and provide a name for the new landing page.

4)    Click Edit Section pencil icon to add fields and sections to the new landing page.

Note that the Header and Content areas are separate sections and each one can be modified.

You can add any section available in the <AppName>-Portal-UIPages class to these landing pages. If a specific custom section needs to be added here, then it needs to be created in the Dev Studio in this class and marked as a relevant record. This way, it will be visible on the list of sections that you can include in the landing page from App Studio. Once the landing page is created, follow step 5 to include it in the portal main menu.

5)   Along with the new pages created in App Studio in Step 4, any harness created in Dev Studio in the <AppName>-Portal-UIPages class and marked as a relevant record will also be visible under the Pages menu. You can now include it as a landing page in the main menu of the portal.

Customizing the dashboard

Dashboards can be personalized for each user. To personalize the dashboard in App Studio, enable Design mode, open the Dashboard landing page, and click Personalize the dashboard icon on the top right. This feature remains unchanged from how it was for applications using UI-Kit.

Customizing case display

A citizen developer can modify certain parts of how a case is displayed in the portal. Follow the steps below to modify basic case display details.

1)    In App Studio, run the case type whose display details need to be modified. Click the Design icon to enter the Design mode.

2)    Click the pencil icon for the Preview section as shown below.

The pencil icon is located in the header of the selected section.

The Preview section is divided into different areas, covering critical data (Top area that displays Status and Priority), primary case data, and additional details (which are empty by default).
