HTML5 Markup cleaned up
It seems that the current Tiny version of the Modx package (4.3.3-pl) does not support html5-tags. (see http://forums.modx.com/thread/?thread=78709&page=1). Whenever you try to add tags like figure/figcaption/article they get removed or replaced with p by the cleanup routines.
Configuration of xconfig.js (tinymce_extended_valid_elements) did not work. Anyway, this configuration should be moved into Modx system settings, just as "invalid_elements" is available there.
I'm eager for a fix here too as it causes me major headaches with a couple of existing sites. I checked the xconfig.js as mentioned in several threads and the HTML5 elements are already listed there, however it does not work.
I noticed the official TinyMCE site shows a HTML5 demo here: http://www.tinymce.com/tryit/html5_formats.php
Maybe the version of TinyMCE included in the MODX plugin needs to be bumped, although I'm not sure how much work this would be and the latest 4.0 version still looks to be in beta.
Yes.. PLEASE fix this.. HTML5 elements should be allowed - this feels like the IE 6 days...when stuff should be working... ugh. OR can someone provide docs how to install the latest TinyMCE so that it works with MODX.
In the short term, look for CKEditor in the MODX Package Manager, seems to like HTML5 elements. :)
The example demo page is using TinyMCE 4.0.6, the current MODX extra version is an older 3.x version. I've forked this to try and start integrating the new version but seem to only be able to break it as the directories and filenames are all different in the major release bump!
Also worth noting that Redactor editor is available from ModMore which is HTML5 out of the box, but you'll have to pay for it!
