A shelf device for mounting on an inside surface of a cooler door comprises a bottom panel and left and right mounting flanges connected to the bottom panel along left and right side edge portions thereof. Each flange has a pair of openings therein vertically spaced from one another and adapted to mount and support the shelf device. A partition panel is connected to the bottom panel and divides the bottom panel into a plurality of compartments. Vertically extending ribs are attached to the partition panel at junctions of adjacent compartments. A display panel is spaced from the bottom panel and attached to the ribs. The display panel includes top and bottom lips forming a slot for slidably receiving a display insert. Ventilation openings in the partition panel increase air circulation.
