About a year ago I ran into a BBC survey. I don't remember what it was asking me, or what I was looking for and how I stumbled upon it, but I remember the experience very well.
I love delving into form design. I get silly excited when there is any kind of form attached to a project I'm working on-- it's a little embarrassing how thrilled I get. So what made this form so great? Here's a drawing I made in hopes that I could ever steal the idea:
One note: I was googling for examples of BBC forms thinking I'd maybe find the real thing. I didn't, but what I did find is an awesome amount of BBC design documentation. And. Within that documentation, I learned that what we call breadcrumbs (homepage-->next page-->page you're on) they call "crumbtrails" across the pond. I think that's lovely.
