A portable shelter having a frame that is separately collapsible in a transverse direction and a longitudinal direction of the shelter to facilitate transportation and storage of the shelter. The frame includes a plurality of ribs, each rib comprising two support legs and at least three roof members forming a generally inverted U-shape when in an erect configuration. The support legs and the roof members are connected with foldable joints such that each rib may be collapsed in the transverse direction to a collapsed configuration wherein width of the rib is narrower in the collapsed configuration than when in the erect configuration. The frame also includes a wall support system connecting adjacent ribs. The wall support system is collapsible in the longitudinal direction to adjust the relative position between adjacent ribs.
