I am pasting the following code into the text editor.
<ul class="faqs"> <li class="navbookmark"><a href="#er1">ABC</a></li> </ul>
After the initial save everything looks fine in preview mode. However, if I go back in to edit the page, the styles applied to ul and li tags get stripped out, and the source looks like this.
<ul> <li><a href="#er1">ABC</a></li> </ul>
How do I prevent this from happening?
