9. A non-transitory computer readable storage medium configured to store instructions that when executed cause a processor to perform creating an attribute category tree data structure having more than one level of tree data, the processor being further configured to perform: receiving a plurality of objects having a plurality of corresponding predefined attribute values; assigning the plurality of predefined attribute values to at least one category value; constructing a first category of the attribute category tree data structure based on a of data associated with the at least one category value; assigning the first category to a first level of tree data, wherein the first category is an image category corresponding to a particular product, and wherein the first category is represented by at least one assigned image file; assigning at least one predefined attribute value of the plurality of attribute values to a second level of tree data, wherein the at least on attribute value comprises a plurality of numerical values corresponding to a plurality of different numerical sizes of the particular product which are available for purchase; assigning, via the processor, at least one additional predefined attribute value of the plurality of attribute values to a third level of tree data that is separate from the first level of tree data and the second level of tree data, and wherein the third level of tree data is linked to the first level of tree data and to the second level of tree data; displaying a plurality of image options available for selection each comprising the at least one predefined attribute value; receiving a selection of at least one of the image options associated with the at least one predefined attribute value; and selecting a branch of the tree under the selected at least one image option and expanding the tree to display available options for the at least one additional predefined attribute value that is available based on the selected predefined attribute value, wherein the available options comprise the plurality of different numerical sizes of the particular product which are available for purchase.
11. The non-transitory computer readable storage medium of claim 9 , wherein the first tree level of tree data is reserved for non-numerical category image data, and the lower tree levels are reserved for category numerical data and category textual data.
