Editable field with a choice?

Question

Django

Hello!
How to create a similar field in Django, where you can select from a list and edit if necessary?

For now, I found the django-floppyforms project and tried it out. In general, it has the same effect, it uses datalist , which does not lend itself to css styles. Is it possible to replace datalist with a ul list ?
forms.py:

class SymbolForm(forms.ModelForm):
    symbol = floppyforms.CharField(widget=floppyforms.TextInput(datalist=['A', 'B', 'C'], attrs={'autocomplete': 'off'}))

    class Meta:
        model = Symbol
        fields = ('symbol ')
