Add checkbox in node menu settings
I would like to add one checkbox in Menu settings at node /node/add/{Content types}
I am not sure how to do that.
I need to use Form and Controller.
What form I need to include? This is some of them.
use DrupalCoreFormConfigFormBase;
use DrupalCoreFormFormStateInterface;
And after I need to implemente Implements hook_form_FORM_ID_alter().
Is my thinking ok?
