Abstract: Techniques are described herein for presenting attribute variations (differing attribute values) of an item at a network page. A request for the network page associated with an item of an electronic catalog can be received. In response to the request, the network page can be presented. The content and/or format of the network page can be predefined by an interface specification associated with the item and/or item category for the item. The network page may include a first area that includes an expanded view in which one or more variations of the first attribute are depicted and any suitable number of collapsed views in which one or more variations associated with a respective attribute are hidden from view. The areas of the network page may be dynamically expanded and collapsed to enable selection of various attribute values which may then be used to update the network page.

Abstract: Techniques for generating and presenting user interfaces that provide a consolidated representation for same or similar products available for acquisition with variations of product attributes is described. A primary user interface (UI) for presenting a product having a product attribute may be presented via a device. The primary UI may present a representation of the product with an indication that alternate product(s) are available with alternate product attributes. Based on receiving a request to access information about the alternate product(s), a secondary UI may be generated for presenting the information about the alternate product(s). The secondary UI, which may overlay a portion of the primary UI, may be presented via the device. Based on receiving an indication of a selection of an alternate product, the presentation of the secondary UI may be terminated and the primary UI may be updated to reflect the selection of the alternate product.
