I also faced the same issue once, Better send the list of choices in your templete and run loop in option tag like this

<option value="None" selected>None</option>
{% for row in vin %}
<option value="{{row}}">{{row}}</option>
{% endfor %}

The problem in your code comes from the way you have defined the choices. The SelectMultipleField field requires the choices to be defined as a list of tuples. Like this :

typess = SelectMultipleField("Type", choices=[("None", "None"), ("one", "one"), ("two", "two"), ("three", "three")], default=[('None', 'None')])
