Removing the default dashes in forms.Select()

Using Django Templates & Frontend
1

I have the following in a form:

fields = ("subjectfk", "name", "about",)
        labels = {"subjectfk": "Subject"}
        widgets = {
            "subjectfk": forms.Select(attrs={"class": "widget"}),
            "name": forms.TextInput(attrs={"class": "widget"}),
            "about": forms.Textarea(attrs={"class": "widget", "rows": 3}),
            "marks": forms.NumberInput(attrs={"class": "widget"}),
        }

and it renders:

2022-05-06_16-05-1651849518

How do replace the ugly “dashes” in the Subject field?

I am also having challenges setting range of values allowable in the “Marks” field. I get errors when I try the following:

forms.NumberInput(min_value=0)

Output:
TypeError: Input.__init__() got an unexpected keyword argument 'min_value'

Lots of confusing blogs out there

See: Form fields | Django documentation | Django

If you want the client-side validation in the field, you should be able to use the min attribute in the attrs dict with the desired min value.

If you want server-side validation, see Form and field validation | Django documentation | Django

(Note, you can do both, but you want to avoid doing client-side validation only. It’s too easily bypassed.)
