hide default post type

Hi,

The post templates cannot be removed from there by a setting. You could try some CSS like this
– https://www.screencast.com/t/r7aUJi0RH
It will target the default post template “Single template”, enter it in the Gutenberg stylesheet here
– https://www.screencast.com/t/mAYyjvv1vDn
Then force refresh the post edit page a few times, it should work.

.td-post-option-general .td-small-wrapper-o a[title$="Single template"] {
display: none;
}

Thanks
