#submit(value = nil, options = {}, &block) ⇒ Object

Add bootstrap formatted submit button. If you need to change its type or add another css class, you need to override all css classes like so:

submit(class: "btn btn-info custom-class")

You may add additional content that directly follows the button. Here’s an example of a cancel link:

submit do
  link_to("Cancel", "/", class: "btn btn-link")
end
