# To prevent this the helper generates an auxiliary hidden field before
# every multiple select. The hidden field has the same name as multiple select and blank value.
#
- # This way, the client either sends only the hidden field (representing
- # the deselected multiple select box), or both fields. Since the HTML specification
- # says key/value pairs have to be sent in the same order they appear in the
- # form, and parameters extraction gets the last occurrence of any repeated
- # key in the query string, that works for ordinary forms.
+ # <b>Note:</b> The client either sends only the hidden field (representing

# In case if you don't want the helper to generate this hidden field you can specify
# <tt>include_hidden: false</tt> option.
