Themes that work with the “Site Editor” (formerly known as FSE themes), including the default TwentyTwentyThree theme, don’t work well with Toolset.
In particular it is not possible to create custom templates or WordPress archives using Toolset with such themes. Also, if you edit the theme templates in the block editor, Toolset dynamic sources and some blocks (e.g. the Fields and Text block) do not work as expected.
Other aspects of Toolset (e.g. creating Views, Forms, controlling access) continue to work normally.
FSE support has now been added.
You can implant your own custom template using FSE’s native templating engine for CPT’s. In your active FSE’s theme folder, create a blank HTML file in a subfolder called ‘templates’. The filename should be single-[your-cpt].html. For example, if you have a toolset CPT called ‘recipe’, and you’re using Twenty-Twenty-Four, simply create a file at:
wp-content/themes/twentytwentyfour/templates/single-recipe.html
Next, in your WordPress dashboard, visit the menu for Appearance -> Editor -> Templates and click on the “single-recipe” template. You can now the block designer to incorporate Toolset and other blocks to customize your template for your custom post type.
Any progress with enabling Toolset to work with Site Editor themes? Could the tutorial information be edited to add a note that at the moment Toolset doesn’t work with such themes? Had that been obvious I could have save a significant amount of time. Thank you.
