Visibility Control for <a href="https://www.nextsoftwaresolutions.com/r/learndash/wp_vcl_plugin_page" rel="nofollow ugc">LearnDash</a> helps you hide messages and content for specific criterion anywhere on your WordPress page.
You can show/hide HTML elements, menus, and other details based on: 
1. User’s access to a particular, any or all LearnDash Course, Or 
2. User’s access to a particular, any or all LearnDash Group, Or 
3. User is Logged In or Logged Out. 
4. User’s role.
You simply need to add a CSS class to your element div or span. As explained here:
Example:
Login/Logout Status:
<ul>
<li>To show the element/menu item to a logged-in user, add this CSS class: visible_to_logged_in OR hidden_to_logged_out</li>
<li>To hide the element/menu item from a logged-in user, add this CSS class: visible_to_logged_out OR hidden_to_logged_in</li>
</ul>
For user’s role: 
* To show the element/menu item to a user will role administrator, add this CSS class: visible_to_role_administrator OR hidden_to_role_administrator 
* Note: To show an element to multiple specific roles only, you need add the element multiple times, one for each role. To hide an element/menu from specific multiple roles only you can add the element once add multiple classes to the same element.
For all the courses:
<ul>
<li>To show the element/menu item to user with access to all the Courses, add this CSS class: visible_to_course_all</li>
<li>To hide the element/menu item from user with access to all the Courses, add this CSS class: hidden_to_course_all</li>
<li>To show the element/menu item to users not enrolled in any Course, add this CSS class: visible_to_course_none</li>
<li>To hide the element/menu item from users not enrolled in any Course, add this CSS class: hidden_to_course_none</li>
</ul>
For a specific course, if Course ID is 123:
<ul>
<li>To show the element/menu item to user with access to above Course, add this CSS class: visible_to_course_123</li>
<li>To hide the element/menu item from user with access to above Course, add this CSS class: hidden_to_course_123</li>
</ul>
For users with access to at least one course: 
* Add this CSS class: hidden_to_course_none
For a course completion status, if Course ID is 123:
<ul>
<li>To show the element/menu item to user who completed above course, add this CSS class: visible_to_course_complete_123</li>
<li>To hide the element/menu item from user who completed above course, add this CSS class: hidden_to_course_complete_123</li>
<li>To show the element/menu item to user who has not completed above course, add this CSS class: visible_to_course_incomplete_123</li>
<li>To hide the element/menu item from user who has not completed above course, add this CSS class: hidden_to_course_incomplete_123</li>
</ul>
For all the groups:
<ul>
<li>To show the element/menu item to user with access to all the groups, add this CSS class: visible_to_group_all</li>
<li>To hide the element/menu item from user with access to all the groups, add this CSS class: hidden_to_group_all</li>
<li>To show the element/menu item to users not enrolled in any group, add this CSS class: visible_to_group_none</li>
<li>To hide the element/menu item from users not enrolled in any group, add this CSS class: hidden_to_group_none</li>
</ul>
For a specific group, if Group ID is 123:
<ul>
<li>To show the element/menu item to user with access to above Group, add this CSS class: visible_to_group_123</li>
<li>To hide the element/menu item from user with access to above Group, add this CSS class: hidden_to_group_123</li>
</ul>
For users with access to at least one group: 
* Add this CSS class: hidden_to_group_none
Mechanism of Functioning
<ul>
<li>Multiple CSS Classes: If multiple visibility control classes are added, ALL of them must meet the criterion to keep the element visible. If any one of them hides the element, it will be hidden. For example: visible_to_group_123 visible_to_group_124 will show the element only to those who have access to both groups.</li>
<li>Hidden data/elements reaches the browser. Though user’s do not see it.</li>
<li>CSS is added to the page for all CSS elements that needs to be hidden based on above rules.</li>
<li>After page is loaded. These elements are removed from page using jQuery (if available), so it won’t be available even on Inspect.</li>
<li>Elements rendered after the page load are hidden but not removed from DOM/page.</li>
</ul>
Future Development
Depending on the interest in this feature, we will decide on adding a shortcode and/or a Gutenberg Block to achieve this feature.
