I want to create a charfield input in a django form that has suggestions. Essentially I want a choice field that also allows you to write your own value if needed. In other words a hybrid between a charfield and choice field input. Any suggestions on how to achieve this ?

forms.py

class PDFClassificationForm(forms.ModelForm):  
    nature = forms.CharField(required=False)
    class Meta:  
        model = Documents
        fields = [,
                  'nature',]
        labels = {,,
                  'nature':'Nature/Concerne:',
                  }
        
    def __init__(self, uuid_pdf, *args, **kwargs):
        super(PDFClassificationForm, self).__init__(*args, **kwargs)
        
        nature_choices=  Archivagerecurrencelibelle.objects.filter(Q(id_emetteur=Documents.objects.get(uuid=uuid_pdf).id_emetteur) & Q(source="Nature")).values_list('concerne','concerne')
        
        self.fields['nature'].choices =  nature_choices
        

views.py

class DocumentsArchiveUpdateView(UpdateView): 
    model = Documents
    template_name = 'documents/documents_read_write.html'
    form_class = PDFClassificationForm
    success_url = lazy(reverse, str)("documents_archive_list")
    
    def get_context_data(self, *args, **kwargs):
    
        # Call the base implementation first to get a context
        context = super(DocumentsArchiveUpdateView, self).get_context_data(*args, **kwargs)
        
        id_customer = Documents.objects.get(uuid=self.kwargs['uuid_pdf']).id_customer
        context["document_owner"] = Entity.objects.get(id=id_customer)
        
        context["uuid_contrat"] = self.kwargs['uuid_contrat']
        context["uuid_group"] = self.kwargs['uuid_group']
        context["uuid_pdf"] = self.kwargs['uuid_pdf']

       
        return context
    
 

    def form_valid(self, form):
        obj = form.save(commit=False)
        obj.id_document_status = DocumentStatusLst.objects.get(id=3)
        obj.save()        
        return super().form_valid(form)
    

documents_read_write.html

{% extends 'layout.html' %}

{% load crispy_forms_tags %} 


<form action = "{%url 'jnt_customer_create' uuid_contrat uuid_group pdfid%}" method="POST" enctype="multipart/form-data">
  <!-- Security token -->
  {% csrf_token %} 

  <!-- Using the formset -->
  {{ form |crispy}} 
  <button type="submit"  name="btnform1" >Enregistrer</button>
</form> 

{% endblock %}
