TinyMCE Advanced While not required to use the plugin it is advised that your website have several features turned on inside the Classic WordPress Editor, including tables, font size selection and the Format selector. These features may be enabled using a plugin called TinyMCE Advanced. There are other similar plugins that will provide the same features but TinyMCE Advanced has been thoroughly tested for compatibility with this plugin. After installing the TinyMCE Advanced plugin choose Settings > TinyMCE Advanced. In the “Unused Buttons” section drag the “Formats” button and place it in the desired location of your editor.
