modeitem

Modeitem is a term used in user interface design and software development to denote an individual option within a mode selector that configures the application into a specific mode. A modeitem is typically part of a control that presents several mutually exclusive modes, such as edit versus view, draw versus erase, or debug versus run.

Etymology and scope: The term combines mode and item to describe a selectable element that governs how the interface behaves rather than what content it displays. A modeitem differs from a typical menu item that navigates to a different screen; instead, selecting a modeitem changes the current interaction paradigm within the same view.

Structure and attributes: In many design systems, a modeitem includes a unique identifier, a display label, and optional iconography. It may carry state such as active, enabled, or disabled, and can belong to a mode group that enforces mutual exclusivity among its peers. Some implementations attach metadata like keyboard shortcuts or descriptive tooltips to assist users.

Behavior and accessibility: Selecting a modeitem updates the application's mode state, refreshes or restricts available actions, and may alter shortcuts or input handling. Implementations commonly use accessibility roles and attributes to convey state to assistive technologies, and they support keyboard navigation and proper focus management.

Implementation examples: In a segmented control, several modeitems form a single control; in a command palette or dropdown, modeitems appear as selectable options that switch the operational mode. In stateful widgets, a modeitem maps to a mode enumeration used by the underlying logic.
