    :param int maxlength: The maximum number of characters (UTF-16 code units) that the user can enter.
        If this value isn't specified, the user can enter an unlimited number of characters.

        You can simply use ``code={}`` or ``code=True`` to enable code style editor.
        You can use ``Esc`` or ``F11`` to toggle fullscreen of code style textarea.

        Some commonly used Codemirror options are listed :ref:`here <codemirror_options>`.
