Community Q&A
How do I enable Gutenberg for an existing custom post type?
You can use the register_post_type_args filter in your functions.php file to set ‘show_in_rest’ to true for your specific post type slug.
Should I use a plugin to create custom post types?
While plugins like ACF are excellent for custom fields, you can register post types manually in functions.php to keep your site lightweight.
Can I use custom post types for calendar events?
Yes, but be aware that handling time zones and recurring events manually can be complex compared to using a dedicated events plugin.
