After deleting the iframe 'Prohibited Element' from the TinyMCE Editor, I have successfully embeded several Youtube videos in a K2 item.

However, I can't get the videos to play in fullscreen mode. The videos contain the fullscreen icon, but clicking on the icon just brings up a message "Fullscreen is unavailable. Learn more"

I have included "fs=1" in the iframe code, however every time I insert "allowfullscreen", after saving, it is deleted from the html code (in much the same way as the entire iframe code was before I deleted the iframe 'Prohibited Element' from the TinyMCE Editor).

Is there a setting I have missed?

Thanks, Peter

Hello Peter,

Is it possible to have a link to the item please?

Hi Krikor,

Thanks for responding. You're not going to believe this, but after much searching, I discovered the solution about 2 minutes before receiving your reply.

Editor - TinyMCE, Extended Valid Elements, I added: ,iframe[*],

Now it doesn't delete "allowfullscreen" from the iframe code.

Thanks again.
Best, Peter

Thank you so much for sharing this Peter :)
