However, this will turn ALL terms checkboxes to radio buttons. Not only that, it’ll turn any checkbox in a meta box – not ideal! Instead, let’s specifically target the wp_terms_checklist() function, which is used to generate the list of checkboxes across the admin (including quick edit). /** * Use radio inputs instead of checkboxes for … Read more
