My question is:

Hi

Creating a select dropdown box with links to methods
What would be the best way to create a form select dropdown box and upon
"submit" have it directly go to a controller method view?
I have something that somewhat works, but I think there is probably a
much easier way to do it. As of now, I have the dropdown list which
when the form is submitted is handed to a controller method which
