See included project 'treewidget' as an example. Widget is used in ModelMultipleChoiceField and allows user to select multiple categories.
django, django-mptt, jquery, jquery-ui
::
from fancytree.widgets import FancyTreeWidget
categories = Category.objects.order_by('tree_id', 'lft')
class CategoryForm(forms.Form): categories = forms.ModelMultipleChoiceField( queryset=categories, widget=FancyTreeWidget(queryset=categories) )
In this example Category is a model registered with django-mptt.
Widget accepts queryset option, which expects pre-ordered queryset by "tree_id" and "lft".
If you want to adjust tree data creation, you can define 'get_doc' method on your model. Example:
::
def get_doc(self, values): doc = {"title": name, "key": self.pk} if str(self.pk) in values: doc['select'] = True doc['expand'] = True return doc
