Block Library: Mockups & Prototype

This is an update to the Block Library project that’s in-progress. Feedback has been taking place on GitHub and in Figma. My thanks to all the folks who have chimed in to help improve these mockups!

Installing a blockBlock Block is the abstract term used to describe units of markup that, composed together, form the content or layout of a webpage using the WordPress editor. The idea combines concepts of what in the past may have achieved with shortcodes, custom HTML, and embed discovery into a single consistent API and user experience.

Installing a third-party block from the block directory, via the block inserter

Search Results

If you search for a block, but nothing installed in your block library shows up, you’re presented with third-party blocks that show the block icon, title, author, and rating. Pressing on a block brings up more details.


The Details screen is similar to the pluginPlugin A plugin is a piece of software containing a group of functions that can be added to a WordPress website. They can extend functionality or add new features to your WordPress websites. WordPress plugins are written in the PHP programming language and integrate seamlessly with WordPress. These can be free in the Plugin Directory or can be cost-based plugin from a third-party cards we see in the Plugin Directory. It’s an abridged version of the block information, showing icon, title, author, star rating, and description. (This would ideally use the short description that plugins provide for cards.)

“More Details” would bring you to the full details screen in the Block Directory, and “Add” inserts the block into your content.


Once the block is inserted into your content, WordPress would ideally start silently installing it in the background while you fill in placeholders and change settings. If you change your mind and decide this block doesn’t work for you, WordPress would deactivate and delete the block when you remove it from your content so you don’t end up with a junk drawer of discarded blocks in your library.

What happens if your installation fails

In some cases, the installation won’t work — for example, if your internet cuts out while trying to install the block. In these cases, WordPress needs a way to recover from that error. This flow explores when a block isn’t able to be silently installed.


If you have the pre-publish panel enabled, you’ll see another reminder that you’ve added new blocks to your site, and another Details link that’ll take you into the Block Directory, in case you want to review it again.

Next Steps

  • The design team will look at creating tests for this (or testing it out themselves) during the WCEU Contributor Day; look for a recap on this p2 afterwards.
  • Between now and then, the prototype will continue to be open for feedback and iteration. I’d like to have all feedback for round one of testing in by Wednesday, June 19th, so I have time to iterate before WCEU.
  • You can comment with feedback here, or directly in Figma, if you’re a part of our team account (You can ask for access in #design).
