Split view
A layout that divides the viewport into two side-by-side panes, often resizable.
Each pane can hold independent content — a list and a detail view, an editor and a preview, two documents being compared. Splits can be vertical or horizontal, fixed or user-draggable. Common in code editors, email clients, and design tools.
