[Flask] Getting values of Flask-WTF SelectMultipleField?

[David Lord]

The same name is supplied multiple times with select multiple fields 
(and this can be done with other fields as well). Use 
|request.form.getlist(name)| to get all values for the given name.

You found an example using Flask-WTF or just straight WTForms and 
conflated it with |request.form| when it was really referring to |form| 
as in “an instance of a |Form|“.
