Dropdown Empty

Hello,

I'am using this form class to populate an dropdown list. My problem the dropdown is empty

class LeadModelForm(forms.ModelForm):
class Meta:
model = InstaProfile
fields = fields = '__all__'
choices = Category.objects.all().values_list('name','name')
choice_list = []

for item in choices:
choice_list.append(item)

widgets ={

'category': forms.Select(choices=choice_list,attrs={'class': 'form-select'}),

}

If a i remove the crispy filter on my html template file is working

Any idea ?

Thank you

Greg
