Custom Widget for CharField Multiple

Hi,
I am trying to create a `CharFieldMultiple`, equivalent to the MultipleHiddenInput or SelectMultiple.

The goal is to have multiple CharField returned as a list, but have not been able to recreate it. My code thus far is:

class CharFieldMultiple(forms.widgets.Input):
    def render(self, name, value, attrs=None):
        if value is None:
            value = []
        final_attrs = self.build_attrs(attrs, type=self.input_type, name=name)
        inputs = []
        for i, v in enumerate(value):
            input_attrs = dict(value=force_text(v), **final_attrs)
            inputs.append(format_html('<input{} />', flatatt(input_attrs)))
        return mark_safe('\n'.join(inputs))

I am trying to figure out how 'value' is set. I noticed that when I manually put value = ['a','b','c'], I will get 3 CharFields, great! But I cannot figure out how to pass that value parameter.

The type-field is still set to None, but I can figure that out later.
Thanks in advance!
