How to do it...

Create an administration interface for the Category model from the categories app that extends treebeard.admin.TreeAdmin instead of admin.ModelAdmin and uses a custom form factory, as follows:

# myproject/apps/categories/admin.pyfrom django.contrib import adminfrom treebeard.admin import TreeAdminfrom treebeard.forms import movenodeform_factoryfrom .models import [e-mail](Category)class CategoryAdmin(TreeAdmin):    form = movenodeform_factory(Category)    list_display = ["title", "created", "modified"]    list_filter = ["created"]
