The Simple hierarchical select module or SHS for short implements a widget element that allows users to drill down through a hierarchical list of terms within a vocabulary.
The module implements a custom formatter, widget and Views filter. You can create a views listing page that allows users to filter content using SHS. The module only works with vocabulary terms so you’ll need to have Taxonomy enabled to use this module.
