I setup a Travel Request form that allows user to select different
options for travel,whether they need: train, air, hotel or car. If any
of the options are selected then optional  fields show up for them to
fill out (like pick times and train/air options,etc.) and if these
options are not selected then they do not show up on the form. Problem
is even when you don't have the option selected it forces you to fill
out the required fields in this sections when you hit submit.
Ex.if you are only taking the train, you have to fill out the required
information under the Train, Airline, Hotel and Car section. I want to
fix the form so that you only have to fill out the required area(s)
that's visible (or selected). Can anyone help me with this. Thank you!
