Hello, what I need to do is to add some custom dropdown list in tinyMce (Episerver 10, tinymce 3).

Scenario:

inside iframe which is rendering content of the page there will be some anchor elements

jQuery selector:

iframe = $('iframe');
popupsAnchors = $('a.Form__Anchor--Popup', iframe.contents());

i need to feed my dropdown with "name" attributes of those and bind "href" attribute as a value.

What I want to achieve finally is to wrap selected part of code with ....

I spend almost whole day yesterday on it, tinyMce3 documentation is very poor. What I achieved right now was to register custom plugin, add custom button and wrap selected text with some dummy wrapper. Can you please help?
