The following is the same configs we had for the CMS11 version of the site. 

However, the CMS12 version does not show the Pargraph and StyleSelect drop downs anymore. (formatselect, styleselect) 

Are we missing anything ? 

services.Configure<TinyMceConfiguration>(config =>
 {
     string[] toolbar = {
        " table | tablerowprops tablecellprops | tableinsertrowbefore tableinsertrowafter tabledeleterow | tableinsertcolbefore tableinsertcolafter tabledeletecol | tablesplitcells tablemergecells " ,
        " epi-link anchor image editimage media paste searchreplace | fullscreen code | undo redo | outdent indent | btnAccordion codesample" ,
        " bold italic underline removeformat | bullist numlist | formatselect styleselect |  alignleft alignright aligncenter alignjustify" };

     config.Default()
             .ContentCss("/content/editor.css")
             .AddPlugin("table fullscreen anchor code link media epi-link image codesample")
             .Toolbar(toolbar)
     .BlockFormats("Paragraph=p;Heading 2=h2;Heading 3=h3;")
     .AddSetting("image_advtab", true)
     .AddSetting("image_title", true)
     .AddSetting("image_class_list", new[] {
        new { title = "None", value = "" },
        new { title = "Image zoom", value = "image_zoom" },
        new { title = "Responsive image", value = "img_responsive" },
        new { title = "Float left image", value = "txtarea-left-image" },
        new { title = "Float right image", value = "txtarea-right-image" }
     })
     .StyleFormats(
         new { title = "Simple Tip", inline = "span", classes = "simpleTip" },
         new { title = "Quote", inline = "span", classes = "quote" },
         new { title = "Warning message", inline = "span", classes = "warningMsg" },
         new { title = "Note", inline = "span", classes = "note" }
     );
 });
