I have created a few checkboxes in field management and they are now displaying within a tab. I am now looking to add some functionality to the boxes but I cannot find any code relating to them in the backend.. I was told that code for them appears in cb.core.php and cb.params.php but I cannot find anything.
Could someone please tell me where this code lies, if it does at all, and where any custom code relating to them should be appended?
