The company has requested to group 3 new Pages, within Claim Details, in the left...

The Guidewire UI is organized into a hierarchy ofLocations, and the primary mechanism for grouping related pages in the side navigation (the "sidebar" or "west panel") is theLocationGroup. When a business requirement calls for grouping multiple pages under a single heading—such as adding three specialized inquiry pages within the "Claim Details" area—a LocationGroup is the standard architectural choice.

A LocationGroup acts as a container for multiple LocationRef elements (which point to specific Pages, Worksheets, or other Groups). By defining a new LocationGroup (Option E), the developer can create a nested navigation structure. This results in a cleaner UI where a single parent entry in the sidebar can be expanded to reveal the three sub-pages. This follows the design pattern used throughout InsuranceSuite (for example, the "Financials" or "Parties Involved" sections in ClaimCenter).

Options A, B, and C are incorrect because they use the wrong widgets or locations for side-navigation logic. TabBar (Option B) is for top-level application switching (like moving between Claim, Policy, and Desktop), not for internal page grouping. InputSet (Option C) is for grouping fields within a page, not for managing navigation locations. MenuItemIterator (Option D) is generally used for dynamic menu generation (like a list of recent claims) rather than static structural navigation. Using a LocationGroup ensures that the navigation remains declarative and consistent with the platform's breadcrumb and security permission logic.
