This add-on for Gravity Forms adds a Chained Selects field type. It builds cascading drop downs where each selection updates the next field, such as Year, Make and Model.

You set up choices with a CSV upload. Developers can use hooks and filters to pull options from databases or APIs, so choices stay current without manual uploads. Showing only relevant choices means fewer options to scroll and better data quality.

Use it for vehicle selection, location filtering, service directories (Industry, Service Type, Specific Provider) and product catalogs (Category, Subcategory, Product)
