I have this problem:
i have a simple html menu on sx portlet
look at the HTML filtering settings of Plone. Of Plone will delete
<script> tags by default and access to the HTML source functionality in TinyMCE should be forbidden be default as well. Content editors should never ever be able to work on HTML directly.
Note esp. section 10.4.2 about portal_skins
is a company intranet and managed by me.
I have to migrate from 4.3 to 5.1. and there are a few pages with CSS style.
for test i disabled html filtering, but not view css style
on 4.3 it works properly
I am not sure if the correct word is 'properly'.
Is there ay reason why you can not add it for example in the theme ?
