Adding Google Map via iframe with CKeditor in an article I want to add to the body of a Drupal node (in my case the default article), the google iframe to embed one map

&lt;iframe src="https://www.google.com/maps/embed?pb=!1m14!1m12!1m3! ... &lt;/iframe&gt;


I use Drupal 7.26, CKEditor as Wisywig editor with the "Standard Package", and everything is working fine.

What I tried after reading many articles:


I set the node to Full Html (of course)
I unchecked "Limit allowed HTML tags" in /admin/config/content/formats/full_html
I put "Use custom formatting options"  to yes in the "Cleanup and Output" section of admin/config/content/ckeditor/edit/Full
... few combination of the above.


What it happens: I edit the article, I insert the html source in the body. I untoggle the source button, everything is disappeared (I go back to source and nothing left).



Note: I don't want to use OpenLayers, I don't want to install modules such Iframe, or SimpleMap, because I just need this map once. It should be working, but my html is still filtered for some reason.
Please see dev.ckeditor.com/ticket/11688 for more details.


  If you are using latest CKEditor for Drupal module then please go to Modules->CKEditor->Configure and edit your profiles. Each of them has ADVANCED CONTENT FILTER setting which can be disabled/enabled or extended.


NOTE: durring checking it has turned out that relase version for drupal OS module hasn't been updated thus you can't see this setting. For now please use development release which has this feature and is fully stable.
