I downloaded a new build of CKEditor 4.4.1 and included the placeholder plugin. I figured out how to modify it so the text field is replaced with a dropdown that includes pre-defined placeholders (see attachment).
Currently our email system replaces placeholders with text. For example it knows to replace {|full_name|} with someone's full name. However the placeholder plugin adds double brackets around everything [[{|full_name|}]].
Is there a way to remove those double brackets so we don't have to change our system to look for them?
