Is there a way to create a datalist field in Flask WTForms?

Question

Does anyone know of a way to create a datalist field using WTForms in Flask?

I know how to create a SelectField but I need to allow the user to enter their own value if it isn't in the list.

This is what I want to do http://www.w3schools.com/tags/tag_datalist.asp

Thanks

You create a simple StringField in your view.

autocomplete_input = StringField('autocomplete_input', validators=[DataRequired()])

In your template you call the field and add the list parameter (remember to pass the entries to your template):

{{form.autocomplete_input(list="id_datalist")}}
<datalist id="id_datalist">
{% for entry in entries %}
<option value={{ entry }}>
{% endfor %}
</datalist>
