In lieu of this post: https://wordpress.org/support/topic/user-role-for-specific-widget?replies=2#post-8778088 I now understand how to add restrictions for a user role to only be able to ADD Available Widgets. My next challenge is that I want to restrict access to sidebars.
For example, I have a user role that has access to only the Text Widget. But let’s say that there is more than one sidebar that uses a Text Widget and I only want ONE Sidebar that uses a Text Widget to be accessible by the user role.
Is this restriction possible?
