        automatic_uploads: true,
        pagebreak_separator: `<div class="page-break" style="page-break-after:always;"><span style="display:none;">&nbsp;</span></div><p>&nbsp;</p>`,
        plugins: [
        "imagetools lists link image paste wordcount pagebreak image code fullscreen",
        ],
        draggable_modal: true,
        toolbar:
        "fullscreen | code image pagebreak undo redo | formatselect | bold italic | alignleft aligncenter alignright alignjustify | bullist numlist outdent indent",
    }}
    />;
