A self-organizing hanging system generally includes at least two main components—bars and keys. The bars have at least three embodiments: standard embodiment, valet embodiment, and shelf embodiment. Each embodiment has variations of embodiments of bars and keys. Each of the bars and keys can have embodiments of magnetic elements and anti-rotation elements. The keys have additional opportunities for variations of embodiments to couple with a product support. In at least one aspect, the bars can be formed with receiver stations at predetermined spacing to cause organized placement for coupling keys with the bars. Further, the bars and keys can be coupled to appear as an integral assembly with one or more external surfaces in planar uniformity.
