Where blocks are used
Pages & Design → Blocks lists every kind of block on your site and where it’s used:
- Content: pages, posts, and other items whose latest draft or published version uses the block. Drafts are marked; items in the trash aren’t counted.
- Patterns: your saved patterns that contain it.
- Templates (if you can change the design): the templates of your current theme that use it.
Click a count to see the list, and a title to open it. By default only blocks in use are shown; choose Show every block type to see the rest.
Blocks marked Not installed come from an extension that was removed. Their content is kept, but it doesn’t appear on your pages; replace those blocks or reinstall the extension. See Extensions.
