Field Dependencies that use "Category/Subcategory" as their controlling field do not work on Service Catalog forms. The Dependent field dropdown simply reads "No Results." Using any other controlling field on the form, it works as expected, but the hardcoded "Category/Subcategory" up top are not fields the user can interact with and therefore do not connect and filter dropdowns. This required our org to creating multiple, identically named, custom fields to limit selection on dropdowns.
