module DrgcmsFormFields

###########################################################################
# Implementation of date_picker DRG CMS form field with help of jQuery DateTimePicker plugin.
# 
# Since javascript date(time) format differs from ruby date(time) format localization
# must be provided in order for date_picker object works as expected. For example:
# 
#   en:
#    datetimepicker: 
#     formats:
#     date: 'Y/m/d'
#     datetime: 'Y/m/d H:i'
#
#   sl:
#    datetimepicker: 
#     formats:
#      date: 'd.m.Y'
#      datetime: 'd.m.Y H:i'
#
# ===Form options:
# * +type:+ date_picker (required)
# * +name:+ Field name (required) 
# * +options:+ options which apply to date_picker field. All options can be found here http://xdsoft.net/jqplugins/datetimepicker/ .
# Options can be defined in single line like:
# * options: 'inline: true,lang: "sl"' or
# 
# * options: 
#   * inline: true
#   * lang: '"sl"'
#   
# * +html:+ html options which apply to date_picker field (optional)
# 
# Form example:
#    10:
#      name: created
#      type: date_picker
#      options: 'inline: true,lang: "sl"'
