[Bastilla123]

Hello,

i need a new widget that generate in template a nested multiselect list view like this:

https://www.jqueryscript.net/demo/Tree-Generator-jQuery-Bonsai/

on submit all entrys are saved.

Models.py:

from django.db import models
from mptt.models import MPTTModel, TreeForeignKey

class Properties(MPTTModel):
name = models.CharField(max_length=32)
parent = TreeForeignKey('self', on_delete=models.CASCADE, null=True, blank=True, related_name='children')

def __str__(self):
    return self.name

class MPTTMeta:
    order_insertion_by = ['name']

class Address(models.Model):
id = models.AutoField(primary_key=True)
properties_link = models.ManyToManyField(Properties, blank=True, default=None,)

forms.py:

from django import forms
from .widget import nestedmultiselectfield

class Addressform(forms.ModelForm):
class Meta:
fields = ('properties_link')
widgets = {'homepage':nestedmultiselectfield()}

Can someone implement this nestedmultiselectfield widget? I will pay for this.

Regards
