Is it possible to use html / if statement in the "HTML before form field" to target which subject the user has selected ?
Example: Subject is car, bike, bus
On selection of car, extra field 1 shows (e.g. car model dropdown)
On selection of bike extra field 2 shows (e.g. bike age radio)
on selection of bus, extra field 3 shows (e.g. bus trips per year text field)
