sorry for my late answer, but i was offline....
@miniwark:
yes, i tried that. i can for sure simply write my iframe tag by hand in the html view of the editor, or when the editor is disabled.
for example:
<iframe frameborder="0" scrolling="no" src="[~28~]"></iframe>
so i can do that by hand, and its no problem for ME, the administrator an the site producer. BUT for the client, who does not know anything about html or how to directly link to the include page (via [~28~]), its will be a problem.
so back to my (2) questions: is there a way in tinymce to include an iframe tag (and specify the parameters) within the wysiwyg-area? and is there another (better) way to include iframes and their source file?
thanks for help!
