“This drilldown menu provides easy navigation of complex nested structures with any number of levels. The entire menu sits within a fixed-size area, and when a node is selected, breadcrumb links appear above the menu options to both deliver feedback and allow quick access back to nodes higher up in the hierarchy.” – Seeing some great potential there, mainly as a replacement to “the bunch of select elements that could be hotwired to eachother” (where a selection in the first one would manipulate the second one, etc.).
