``manage_page_footer`` at the bottom. These variables are acquired
by your product and draw a standard management view header, tabs
widgets, and footer. The management header also includes CSS

-- 'form-title' -- Form titles.
-
-- 'form-label' -- Form labels for required form elements.

-- 'form-optional' -- Form labels for optional form elements.
