CKEDITOR.appendTo is basically to place editors
inside existing DOM elements. Unlike CKEDITOR.replace,
a target container to be replaced is no longer necessary. A new editor
instance is inserted directly wherever it is desired.
This editor is using an <iframe> element based editing area, provided by the Wysiwygarea
plugin.
CKEDITOR.appendTo( 'container_id',
{ /* Configuration options to be used. */ }
'Editor content to be used.'
);
This editor is using an <div> element based editing area, provided by the
Divarea plugin.
CKEDITOR.appendTo( 'container_id',
{ extraPlugins: 'divarea' },
'Editor content to be used.'
);
