Try this "dummy" preferences code to see what I'm suggesting:

(require 'wid-edit)
(require 'cus-edit)

(defun preferences ()
  "Create a buffer containing popular customization options."
  (interactive)
  (let ((name "*Preferences*"))
    (kill-buffer (get-buffer-create name))
    (pop-to-buffer (get-buffer-create name))
    (custom-mode)
    (buffer-disable-undo)

    (widget-insert "Display Options\n\n")

    (widget-create 'checkbox)
    (widget-insert " Auto Reveal hidden text\t")
    (widget-create 'push-button :tag "Advanced")
    (widget-insert "\n")

    (widget-create 'checkbox)
    (widget-insert " Show trailing Whitespace\t")
    (widget-create 'push-button :tag "Advanced")
    (widget-insert "\n")

    (widget-create 'checkbox)
    (widget-insert " Indicate Empty Lines\t\t")
    (widget-create 'push-button :tag "Advanced")
    (widget-insert "\n")

    (widget-create 'checkbox)
    (widget-insert " Display Image files\t\t")
    (widget-create 'push-button :tag "Advanced")
    (widget-insert "\n")

    (widget-create 'checkbox)
    (widget-insert " Highlight current line\t")
    (widget-create 'push-button :tag "Advanced")
    (widget-insert "\n")

    (widget-create 'checkbox)
    (widget-insert " Blinking cursor\t\t")
    (widget-create 'push-button :tag "Advanced")
    (widget-insert "\n")

    (widget-create 'checkbox)
    (widget-insert " Auto resize minibuffer\t")
    (widget-create 'push-button :tag "Advanced")
    (widget-insert "\n")

    (widget-insert "\nEditing Options\n\n")

    (widget-create 'checkbox)
    (widget-insert " Auto Expand Abbreviations\t")
    (widget-create 'push-button :tag "Advanced")
    (widget-insert "\n")

    (widget-create 'checkbox)
    (widget-insert " Auto Revert changed files\t")
    (widget-create 'push-button :tag "Advanced")
    (widget-insert "\n")

    (widget-create 'checkbox)
    (widget-insert " Auto Save files\t\t")
    (widget-create 'push-button :tag "Advanced")
    (widget-insert "\n")

    (widget-create 'checkbox)
    (widget-insert " Auto Expand Abbreviations\t")
    (widget-create 'push-button :tag "Advanced")
    (widget-insert "\n\n")

    (widget-insert "         ")
    (widget-create 'push-button
                   :tag "Save"
                   :help-echo "\
Make your editing in this buffer take effect for future Emacs sessions."
                   :action (lambda (widget &optional event)
                             (Custom-save)))
    (widget-insert "   ")
    (widget-create 'push-button
                   :tag "Cancel"
                   :help-echo
                   (lambda (&rest ignore)
                     (cond
                      ((eq custom-buffer-done-function
                           'custom-bury-buffer)
                       "Bury this buffer")
                      ((eq custom-buffer-done-function 'kill-buffer)
                       "Kill this buffer")
                      (t "Finish with this buffer")))
                   :action #'Custom-buffer-done)
    (widget-insert "\n\n")
    (widget-setup)
    (buffer-enable-undo)
    (goto-char (point-min))))
