We must be able to integrate a youtube video in the rich text control, is it possible to use the functionality “view html” of kendoui editor ?
Please consider this article: https://cyrilogc.wordpress.com/2017/09/02/customizing-kendo-ui-editor-1/
and this forum topic: Sharepoint Rich Text Control, missing text color selector
I hope you’ll find it useful.
Anyway, if you have any questions about implementation - feel free to ask!
