Commenting out in HTML editor breaks template

Question

There is a certain section of HTML that I need to comment out within the HTML editor in Wordpress. But when I do so, it breaks the HTML. After looking at the source code, I noticed that it converts the ending comment of this:

-->

To this:

–>

Anyone know how to go about commenting out HTML code within the editor without it converting it to that character?

Answer 1

My last comment reminded me about shortcodes, and lead me to this answer:

function htmlcomment_shortcode( $atts, $content = null ) {
   return '<!-- ' . $content . ' -->';
}
add_shortcode( 'htmlcomment', 'htmlcomment_shortcode' );

Add that to functions.php or your plugin, and then use it in your content like this:

normal text [htmlcomment]commented out text[/htmlcomment]
