Cannot find save as HTML

Hey zioludo,

the option only exists for the bundled chromium browser and not for the CEF browser we are shipping nowadays as a default. You can still download the bundled chromium as an extension and change the used browser in the JavaScript preferences.
The more important question is, why you would want this. As was pointed out in the thread you have linked the output html is completely static and is pretty much the same as if you would just use the image output of the view.

Having the HTML with interactivity is not possible at the moment. There was a feature request recently in the #feedback thread requesting exactly this (Need an HTML render node for Interactive Views - #4 by iCFO).
