Query Loop Block in Widget Areas

[douglas-johnson]

What problem does this address?

I am working on a site that uses a classic theme, but we're trying to use the block editor in every place possible. I would like to include a list of posts from a custom post type in a widget area, but haven't been able to make this work with features available in WordPress core 6.1.1

I am unable to add a core/query block to a widget area. I have not been able to find a specific piece of code that prevents this, but the query related blocks are not listed under the theme category when I try to add a block.

I could not find documentation about why this is the case. The closest I found was a support ticket on WordPress.org that mentioned pagination blocks were not available in widget areas.

What is your proposed solution?

It would be helpful for my transition from classic themes to full site editing if widget areas could contain core/query without pagination or if core/latest-posts supported custom post types.

Some blocks for FSE seem to be explicitly opted out, as seen in #32761, #32756.

From a quick test, the query loop block seems to work well,

However, I would like to wait for advice from someone more knowledgeable to see if this causes any problems or issues that need to be resolved.

I think most of those blocks are disabled as the widget editor has no way to save full site editing 'entities'. That possibly doesn't apply to the query block, as I don't think the post content is editable. Maybe it will be in the future, I don't know.

This is a duplicate of #32952, so I'll close it.
