Form options helpers

- [Instructor] In addition to the form helpers…we saw on the last movie,…Rails also offers us form helpers…to work with select option tags,…that is when a form needs a pulldown menu of options…that a user can choose from.…We will begin by looking at the simplest, the select helper.…The syntax of the select helper…is that it takes a series of arguments,…the first of which is the object we're working with,…the second is the attribute on that object.…Then, we have a list of choices.…These are the choices that the user…is going to select between.…After that would come a hash of options,…and a hash of any HTML options.…
