The site I am building uses fields (plus a custom module) to provide a richer set of relationships between taxonomy terms than the built-in hierarchy allows.
I want to remove/disable the built-in hierarchy. What I mean is that when a user is creating or editing a term, I do not want them to see the “Relations” section, and when they are viewing a list of terms in a taxonomy, I want the drag-and-drop functionality to only work for ordering, not indenting.
I know I can do this with another module using hook_form_alter() or the like, but is there an easier and quicker way to “turn off” this functionality in Drupal 8? I have a vague memory of (maybe in an earlier Drupal, or somewhere else) being able to specify, when you create a taxonomy, if you want it to be hierarchical or not, but I cannot find such a thing here.
