Default Filters

The default filter method in Joomla! is 'Black List'. The default 'Black List' contains the following tags to

exclude:

'applet', 'body', 'bgsound', 'base', 'basefont', 'embed', 'frame', 'frameset', 'head', 'html', 'id', 'iframe',

'ilayer', 'layer', 'link', 'meta', 'name', 'object', 'script', 'style', 'title', 'xml'

The default 'Black List' contains the following attributes to exclude:

'action', 'background', 'codebase', 'dynsrc', 'lowsrc'

You can 'Black List' (disallow) additional tags and attributes by adding to the Filter tags and Filter attributes

fields, separating each tag or attribute name with a space or comma. If you select a Filter Type of "Black

List", this list will always be used, plus any additional tags and attributes you add.

Please note that these settings work regardless of the editor that you are using. Even if you are using a

WYSIWYG editor, the filtering settings may strip additional tags and attributes prior to saving information

in the database.
