I am trying to embed a lead form into my website with creator but I don't want to scare the client with tons of questions (fields) that are relevant only if a certain service is requested. So I would like to show 10 fields or so, but if one of those fields is marked "Yes" the client, a few other fields appear for him to input additional information. So the form would start off small, but then grow as the lead puts more information in?

Is this possible? 

Thanks!
