This plugin implements 2 new shortcodes.
[widget name=”” classname=” instance=””] to use a widget per shortcode in the content area from a page/post.
name is the name of the widget, e.g. Calendar. 
classname is the name of the PHP Class that implement the widget. 
You can use name or classname.
So are [widget name=”Kalender” instance=”title=Hello,World!”] 
and [widget classname=”WP_Widget_Calendar” instance=”title=Hello,World!”] 
produce the same output.
instance are the attributs of the widget. e.g. title=Hello,World! so the complete shortcode is 
[widget name=”Calendar” instance=”title=Hello,World!”]
For the instance list of the WordPress builtin Widgets look at https://codex.wordpress.org/Function_Reference/the_widget 
For other Widgets look at the source code from the widget or ask the widget author.
[sidebar name=””] to use a sidebar (with all widgets) in the content area from a page/post.
name is the name of the sidebar e.g. Showcase Sidebar so the complete shortcode is 
[sidebar name=”Showcase Sidebar”]
For own css styling, the plugin wraps the widgets in < div id=”Widget_Name” class=”widget_shortcode”> and the sidebar in < div id=”Sidebar_Name” class=”sidebar_shortcode”>

Widget or Sidebar Shortcode

Use widgets or sidebars per shortcode in the content area from pages/posts

FuzzGuard

This plugin allows you to display widget items based on if a user is logged in, logged out or based on the role you have given the user.
This plugin allows fine-grained permissions to be added to each individual widget item to display or not display the item based on the 
 users logged in/logged out status or the role assigned to the user. This solves the problem of having to modify theme functions.php files to add in widget restrictions. The changes in functions.php is often overwritten by a theme update. This plugin removes that worry, as you can update the theme, independent of the plugin.

Privilege Widget

This plugin allows you to display widget items based on if a user is logged in, logged out or based on the role you have given the user.
