In SiteSetup, when I configure tinymce and add plugins from the available list, some plugins add into the toolbar of the editor, some don't. For example:
some plugins that add when selected:
fullsize, directionality, previw, datetime.
some plugins that don't add when selected:
anchor, text color, etc.
================================================
I am using Plone 5.1.0.1 ;however, I've seen the same problem in all of the latest versions. I remember way back with Plone 4, these plugins worked.
Also, I checked at the plone demo site, same issues
Side Note: the 'insert horizontal line' stopped working in this version. clicking on the button does nothing (looking a source code does not show the 'hr'. ). I confirmed it wasn't added to html filtering by mistake.
you helped me get it on the tool bar; however, as you suspected, it is filtered.
after adding color to text, it displays that color while still in edit.
saving removes color
however, looking at the html code, adding a color adds a span tag. That isn't how color is added. (https://www.w3schools.com/tags/tag_font.asp) Why is span tag used? (Note: the span tag is on the allowed list, so it shouldn't be filtered.
I tried turning off html filtering but color still not shown. (Note: i did see the warning about caching, and I wasn't sure how to deal with that, so I can't be certain caching isn't the issue.
==========
Note: in your list of text to add you had:.... "| anchor | forecolor backcolor" (no quotes).
I assumed you had forgotten to add the | between forecolor and backcolor. I tried it both ways and both seems to work. Not sure if it matters
Like @espenmn said, the html filtering control panel is where all this stuff is managed.
You can get
<hr>
back by explicitely adding hr to valid tags. I don't know how to allow color withour disabling completely html filtering. And the | characters don't have any meaning, they are purely cosmetic.
Plone 4 Tinymce version is much older and was working differently (oldies but goldies)
