How do I get fonts and font sizes to show?

[grimace]

In my pluginsOpts I have:

'grapesjs-plugin-ckeditor': {
            /* ...options */
            extraAllowedContent: '*(*);*{*}', // Allows any class and any inline style
            allowedContent: true, // Disable auto-formatting, class removing, etc.
            enterMode: 2, // CKEDITOR.ENTER_BR,
            extraPlugins: 'sharedspace,justify,colorbutton,panelbutton,font',
            toolbar: [
              { name: 'styles', items: ['Font', 'FontSize']},
              { name: 'basicstyles', items: ['Bold', 'Italic', 'Underline', 'Strike', 'Subscript', 'Superscript', 'RemoveFormat'] },
              { name: 'paragraph', items: ['NumberedList', 'BulletedList']},
              { name: 'links', items: ['Link', 'Unlink']},
              { name: 'colors', items: ['TextColor', 'BGColor']},
            ],
            font_names: 'Arial/Arial, Helvetica, sans-serif;' +
              'Comic Sans MS/Comic Sans MS, cursive;' +
              'Courier New/Courier New, Courier, monospace;' +
              'Georgia/Georgia, serif;' +
              'Lucida Sans Unicode/Lucida Sans Unicode, Lucida Grande, sans-serif;' +
              'Tahoma/Tahoma, Geneva, sans-serif;' +
              'Times New Roman/Times New Roman, Times, serif;' +
              'Trebuchet MS/Trebuchet MS, Helvetica, sans-serif;' +
              'Verdana/Verdana, Geneva, sans-serif',
            fontSize_sizes: '8/8px;9/9px;10/10px;11/11px;12/12px;14/14px;16/16px;18/18px;20/20px;22/22px;24/24px;26/26px;28/28px;36/36px;48/48px;72/72px'
          }
         

but the fonts do not show. just block-styles in the 'Styles' drop down. How is showing fonts accomplished?
