Salutations contains a list of salutations (Mr, Mrs, Ms, etc) - sometimes also known as prefixes or honorifics - for usage in forms, and ordered by usage.
To use in a form:
<%= f.select(:salutation, options_for_select(Salutations::get)) %>
You can also select Salutations by theme like so:
Salutations::FORMAL
=> ["Sir", "Madam", "Dame", "Lord", "Lady", "Viscount"]
