A server device may be configured to transmit, to a client device, data and program code that instructs the client device to display a graphical user interface using the data. The graphical user interface may include a plurality of parallel lanes that are displayed according to a logical ordering. The parallel lanes may contain handle components for dragging the lanes in a direction substantially perpendicular to the parallel lanes. The selection, dragging, and release of a handle component of a particular parallel lane may cause the graphical user interface to: (i) upon the selection, automatically collapse the parallel lanes, (ii) upon the dragging, slide the particular parallel lane among the set of collapsed parallel lanes, and (iii) upon the release, automatically expand the parallel lanes into a different logical ordering defined by where the particular parallel lane was released.
