One of the holy grails of blocks, as far as I am concern, is post loops. To me, this is the essence of dynamic blocks and over time I have used several tags to keep track of the blocks I review that include this feature in some capacity, most notably:
A very simple plugin to limit visibility of your content based on user roles, while offering an alternative area to add the content that will be shown to non logged-in users.
This block could be used to create a simple membership site, for instance.
We could also insert a reusable block in the “public” area with a call to action asking visitors to register, in order to gain access to that content.
This is what the plugin looks like in the backend:
The plugin has a setting to specify the exact user role that will have access to a given instance of the block:
The author of the plugin mentions some features coming down the road:
Password Reset Block
Restrict entire pages / posts, not just inline content
The plugin looks a little bit abandoned at the moment (no updates for the last 9 months) but I was able to confirm it works fine both with the WP core version of the editor (5.2) and with the beta/plugin version (6.6.0)
