ctools_dependent_element_info_alter in includes/dependent.inc

CTools alters the element_info to be able to add #process functions to every major form element to make it much more handy to use #dependency, because you don't have to add #process.

File

includes/dependent.inc, line 133

Provide dependent checkboxes that can be easily used in forms.
