singlepane

Singlepane is a user interface layout concept in which only one primary content pane is visible at a time. In singlepane designs, navigation updates the current screen entirely, presenting a new full-screen view rather than updating another pane alongside it. This approach is common in environments with limited screen width, such as mobile devices, where it helps maintain clarity and readability.

A typical singlepane pattern involves a list or folder view on one screen and a detail view that replaces the list when an item is selected. Navigation usually uses a back control or a system back gesture to return to the previous screen. This contrasts with two-pane or split-view layouts, where a list and its detail can be shown side by side on larger devices.

Singlepane layouts are favored for their simplicity and predictable navigation flow. They minimize on-screen clutter and make it easier to focus on a single task. However, they can require extra taps to access related content and may cause users to lose context when moving between views, especially if the app does not clearly reflect the navigation hierarchy.

Implementation considerations include using responsive design techniques to switch to multi-pane layouts on wider screens, carefully managing a navigation stack, and ensuring smooth transitions that preserve context. Developers should consider back-stack behavior, loading states, and consistent visual cues to indicate the relationship between screens.

Examples of singlepane usage appear in many mobile apps that present a list and a detail view, such as email clients, news readers, and contact lists. See also master-detail interface and split view.
