1) Is there a way to use a WYSIWYG field as a sub-field of a cloneable group? I can't get automatic paragraphing to work. It works on upper level fields.
2) Using select2 (Select Advanced) field, js_options tags: true adds the ability to input new choices and it also saves it to the database. Is there a way (callback function?) to fetch that newly added choice to the choices list so that when I update the post again all the added choices are kept instead of being dropped?
Currently, Meta Box does not support saving the new tags (free text) to the database and updating that option to the choice list. I will inform the development team to consider adding it to the to-do list for the future development of the plugin.
