I would like to finish my cascading drop downs form adding "Programm" dropdown and booking button with dynamic URL dependent on previos choise(I have already Car brand>Car model => *textfield*Car size .) Car size has only 3(Small,Medium,Large) variations. Programm has 12(4 per each size)
For Example: I'm choosing dropdowns brand and model than comes the size of the car up automatically in the text field: Audi > A4 => *textfield*Medium. Next step is to come out with the choice of washing "Programm" for Medium size car. Than the last thing is, to create a dynamic Booking button with generated URL dependent on previos choice.
For Example: (I have names in German) Audi > A4 => Medium > Aussenreinigung M = > BOOKING BUTTON with LINK : [url removed, login to view]:4517648=Audi%20A4 - link is transfering us direct to chooised programm with prefilling car field.
One more thing: Would be possible using booking button open the content with dynamical URLs from external source on my webpage in a frame or window?
