django-mptt-autocomplete provides a widget using the fancytree js library to render a forms.ModelMultipleChoiceField as a tree with selectable and collapsable nodes with an autocomplete to search in existing tree.
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,model=Category)
)
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
