Object control type is the most simple control that is created by a simple javascript object:
blog_article: {}
Will result in this:
Completely removes the frame around the object.
Usage:
$blog_article_noframe: true,
blog_article: {}
Makes the object collapsible in the admin interface. Good for deeply nested or large objects.
Usage:
$blog_article_expander: true,
blog_article: {}
