How to add attributes to option tags in django ?

Question

I have to add title attribute to options of the ModelChoiceField. Here is my admin code for that:

class LocModelForm(forms.ModelForm):
        def __init__(s

Here is a solution if you want to use the instance to set the attribute value.

class IconSelectWidget(forms.Select):
    def create_option(self, name, value, *args, **kwargs):
        option = super().create_option(name, value, *args, **kwargs)
        if value:
            icon = self.choices.queryset.get(pk=value)  # get icon instance
            option['attrs']['title'] = icon.title  # set option attribute
        return option

class LocModelForm(forms.ModelForm):
    icons = forms.ModelChoiceField(
        queryset=Photo.objects.filter(galleries__title_slug='markers'),
        widget=IconSelectWidget
    )
