Itemsections

Itemsections is a generic data organization construct used in software design to group items into labeled sections. It provides a way to organize large collections of items into logical units, enabling structured display, navigation, and manipulation in user interfaces and data models.

In practice, an itemsections collection consists of multiple section objects. Each section typically has an identifier, a title or label, and an array of items. Additional metadata such as a subtitle, color, or creation date may accompany the section. The overall structure supports operations that span multiple sections, such as iterating over sections to render content or filtering items within sections.

Common use cases include lists in applications, catalogs, or dashboards where items are naturally grouped by category, status, or attribute. For example, a recipe app might present sections for Breakfast, Lunch, and Dinner, each containing relevant recipes. Data sources may expose itemsections to APIs or UI components that render grouped data and provide navigation cues.

Access patterns include retrieving all items in a section, moving an item between sections, or reordering sections and items. Designers should consider performance for large datasets, ensure stable identifiers, and provide accessibility labels for section headers. Related concepts include data grouping, collections with sections, and APIs that render grouped data, as well as common UI patterns such as expandable headers and sectioned lists.
