Coding web forms in static HTML can be a royal pain, especially with super-long option and select groups for choosing countries and state/provinces.
Wufoo makes form design and coding easy as pie. I’ve been using their form building application since it launched—mostly for prototyping and brainstorming. This newly-launched gallery is great for trying out your ideas and viewing prototypes that are already built out for you.
If you aren’t the HTML/CSS type you can still find this gallery useful — browse the forms and then download the code for use in your projects.
