Some CKEditor plugins provide additional filter settings. In the case of Limit allowed HTML tags and correct faulty HTML, we are provided with a list of the Allowed HTML tags. Anything that is not present in the list will be stripped out by the WYSIWYG when a user saves their content.

Sometimes we may need to modify this list. A perfect example is an anchor tag that generally needs to have a title attribute or a target attribute added to it. If we do not modify the Allowed HTML tags to accept these two attributes, then users may be confused if they choose to add these to a link and they do not work, since the filter would strip the attributes out.

We can easily add additional attributes for a link element by modifying the following:

<a href hreflang> 

to be

<a href hreflang title target> 

Now if we click on the Save configuration button, anytime a user needs to add those attributes to an anchor link they will function properly.
