I need to add a css class selector to the webeditor buttons. I already found the location where I need to do this ( /sitecore/system/Settings/Html Editor Profiles/Rich Text Full/WebEdit Buttons ) but I have no clue what to add to get the Dropdown there.
It's comparable with this question(@Raskolnikoov thx for the image): Add buttons/dropdownlist to sitecore webedit editor? but I need to add the full dropdownlist just like in the full text editor
