As already mentioned in a previous article, the otherwise very decent Webforms for Marketers module of Sitecore is in need of an update. The release of HTML5 has had an especially great impact on how we build forms on the web. This is the reason why I have made some HTML5 extensions to the WFFM module.
In this article I will show how to add a textbox with an expandable dropdown list underneath it. It is still a textbox, so the user is able to enter free text. But at the same time it has a list of suggestions that expands when the users focusses on the form or begins typing.
