I'm creating everything in the UI (Meta Box Builder) and I'm looking for a solution using the UI only.
I have added a Wysywig Editor to a field group, and I'm trying to configure TinyMCE. Problem is, all the solutions I find are about editing the code directly. The UI offers the possibility to add options, but it's unclear how the text entered in the option is being parsed and translated into code in the background, and I have found no explanation of it. So far, my attempts don't work.
