Hi have gone through documentation of TinyMCE but could not able to find why TinyMCE Stripped the allowfullscreen attribute In iframe ? When I insert and re-edit it stripped . Tried iframe URL
<iframe src="http://players.brightcove.net/4338955589001/Bkh63tBcx_default/index.html?videoId=5347595845001" width="320" height="240" allowfullscreen></iframe>
Live Fiddle code. Thanks for help
You can use the valid_elements attribute to tell TinyMCE what valid elements and attributes are allowed in the editor.
I updated your fiddle with the following configuration line:
valid_elements: "*[*]"
Admittedly you likely don't want to include all tags and all attributes but this shows that you can get this working.
Please note that your Fiddle is using TinyMCE 3.5.x - that version of TinyMCE is no longer under development. It would be a really good idea to move to TinyMCE 4.5 which is the current release and under active development. If you use TinyMCE 4.5 you can use extended_valid_elements as opposed to valid_elements.
