# == Sending Messages:
# To send Messages via contact forms you can create your form fields in the config.yml
# === Example:
# Make an Element with this options inside your @elements.yml file:
#
#   - name: contact
#     display_name: Kontaktformular
#     contents:
#     - name: mail_to
#       type: EssenceText
#     - name: subject
#       type: EssenceText
#     - name: mail_from
#       type: EssenceText
#     - name: success_page
#       type: EssenceText
#
# The fields mail_to, mail_from, subject and success_page are recommended.
# The MessagesController uses them to send your mails. So your customer has full controll of these values inside his contactform @element.
# 
# Then make a page layout for your contact page in the page_layouts.yml file:
# 
#   - name: contact
#     display_name: Kontakt
#     unique: true
#     cache: false
#     @elements: [pageheading, heading, contact, bild, absatz, file_download]
#     autogenerate: [contact]
#
# Disabling the page caching is stronlgy recommended!
#
# The editor view for your @element should have this layout:
# 
#   <%= render_essence_editor_by_name(@element, 'mail_from') %>
#   <%= render_essence_editor_by_name(@element, 'mail_to') %>
#   <%= render_essence_editor_by_name(@element, 'subject') %>
#   <p>
#     Folgeseite: <%= page_selector(@element, 'success_page') %>
#   </p>
# 
# Please have a look at the alchemy/config/config.yml file for further Message settings.
