in ckeditor i tried to add button with style from source then submit, in page button code and style appeared in as a normal text checking the ckeditor again and it replace my code within <p> tag so ? any help or someway to change it with another one support that ?
Not sure if I understood the problem completely but I think you are complaining about not being able to input 'raw code' through CKEditor.
If that is indeed the case, that would be because Couch, as a security measure, allows only a very strict subset of HTML as input. It 'sanitizes' the rest of the tags (and so they appear as printable characters).
If you really must input raw code through the richtext editor, one way would be to use 'shortcodes' (e.g. see viewtopic.php?f=8&t=7950).
The preferred method would be to use type 'textarea' editable region for this purpose (instead of richtext) and then set its 'no_xss_check' parameter to '1'. Please search the forum for that term an you'll find several posts discussing this.
Hope it helps.
