Widget that holds the dir-locals customizations.
Source Code
;; Defined in /usr/src/emacs/lisp/cus-edit.el.gz
;;; Directory Local Variables.
;; The following code provides an Easy Customization interface to manage
;; `.dir-locals.el' files.
;; The main command is `customize-dirlocals'. It presents a Custom-like buffer
;; but with a few tweaks. Variables are inserted in a repeat widget, and
;; update its associated widget (the one for editing the value) upon the user
;; hitting RET or TABbing out of it.
;; This is unlike the `cus-theme.el' interface for editing themes, that prompts
;; the user for the variable to then create the appropriate widget.
