After doing some research in google for pretty long time found some info on Drop down menu, but the documentation doesn't have clear information for me to understand, or other docs are mostly on TinyMce3. I've customized TinyMce 4 adding a button, menu and sub-menus and have used Window Manager with text box and radio button(which is a checkbox, poor efforts I know), but I need a drop down list/listbox in Window Manager
edit : Radio buttons are not supported in tinymce4
