It’s possible to parse shortcodes within the visual editor of TinyMCE and make them render actual content, rather than the shortcode itself.
Switching to the
Text tab allows you to see the actual shortcode again.
Below are the built-in WordPress shortcodes that use this functionality.
[audio] shortcode allows you to embed a single audio file.
[caption] shortcode wraps the image in a div and puts a
<p class="wp-caption-text"> tag around the caption.
[gallery] shortcode allows you to embed several images at once in a div.
[playlist] shortcode allows you to attach more than one media file and render with an html5 playlist.
[video] shortcode is very similar to the
[audio] shortcode, it simply renders a video instead of audio.
