@girishpanchal30 can you please help me test this?
I've tried creating a child theme for Neve, with support for block templates parts, and tested with this PR, but I'm not seeing any change, and I'm not sure if I'm testing properly
neve-child-master.zip

girishpanchal30 · 2026-01-19T12:47:33Z

@rodica-andronache I have fixed it with the latest commit. Please check it and let me know if any changes are needed.

Pull request overview

This pull request updates the asset enqueuing logic to support themes that use block-template-parts in addition to those that use full block-templates. This allows the plugin to work correctly with classic themes that have adopted block-based template parts.

Changes:

Modified theme support checks to include block-template-parts alongside block-templates
Added fallback logic to load all template parts when full template content is unavailable
Updated test selectors to match WordPress block editor's namespaced class structure

Reviewed changes

Copilot reviewed 3 out of 3 changed files in this pull request and generated 6 comments.

Loading all template parts when $_wp_current_template_content is empty could have performance implications, especially on sites with many template parts. Consider documenting this as a known limitation or exploring alternative approaches to determine which template parts are actually being used.

The parameter name should be 'slugs__in' (with an 's'), not 'slug__in'. This is inconsistent with the existing usage in the codebase (see inc/class-blocks-css.php line 134) and will cause the slug filtering to not work correctly.
