module DrgcmsFormFields
  
###########################################################################
# Implementation of readonly DRG CMS form field. 
# 
# Readonly field value is just painted on form.
# 
# ===Form options:
# * +name:+ field name
# * +type:+ readonly
# * +eval:+ value will be provided by evaluating expression. Usually dc_name4_id helper
# can be used to get value. Example: dc_name4_id,model_name_in_lower_case,field_name 
# 
# * +readonly:+ yes (can be applied to any field type)
# 
# Form example:
#    10:
#      name: user
#      type: readonly
#      html:
#        size: 50
#    20:
#      name: created_by
#      type: readonly
#      eval: dc_name4_id,dc_user,name
