class BlogPostForm(ModelForm):



class Meta:
    model = BlogPost
    fields = ("title","body","tags")



    widgets ={
      'title' : TextInput(attrs={'class':'form-control ' ,'placeholder':'Title'}),
       'body' : TextInput(attrs={'class':'form-control'}),

    }

date  = models.DateTimeField(default=timezone.now)
slug = models.SlugField()

You can use ModelMultipleChoiceField to select multiple tag in tag form, like this:

tags = forms.ModelMultipleChoiceField(label='Tags', queryset=Tag.objects.all())

queryset: A QuerySet of model objects from which the choices for the field are derived and which is used to validate the user’s selection. It’s evaluated when the form is rendered.

if you have the model about Tag, it can try the example code.

More information can be found here: https://docs.djangoproject.com/en/4.1/ref/forms/fields/#modelchoicefield
