Hi! Just started to dig into PW and since I have a small project starting I wonder that how does PW support dynamic forms out-of-the-box? Or perhaps through some module(s)? I'm creating a form(for visitors) that has options such as shape > size > color > availability/product which filter values for the last filter/select option (in this case availability). And is there any form field dependency implemented or is this just a matter of e.g. jquery events that trigger AJAX or visibility when field value is changed?
