[Answered ]-How would you create two select menus where select menu B's contents are dependent on select menu A's selection?

You can use django-autocomplete-light to do this. This basically provides autocompletion using a client library such as select2. But it also provides a way to filter results based on another field.

You should likely also make a server verification in the form clean:

class MyForm(forms.Form):

    project = forms.ModelChoiceField(queryset=Project.objects.all())
    task = forms.Model.ChoicField(queryset=Task.objects.all())

    def clean(self):
        project = self.cleaned_data['project']
        task = self.cleaned_data['task']
        if task.project_id != project.pk:
            raise forms.ValidationError(
                "The selected task does not belong to the selected project.")
