I would like to create a Car year/model/series/bodyType cascading dropdown controller. What is the best approach?
For a demo I can use a subset of data
Composer has this concept of a "Cascading drop-down list manager", where you can upload a structured XML file which defines the structure of the data, and then you just need to point your Cascading Dropdown Lists at the data, and define the XPath which points to the node(s) with the data in it. There must be an equivalent of this where the data could potentially be managed in Excel and exported-imported into the form design.
