# Displays all filters as a select box to save space, also
# has a javascript to manage filters that are of type multival
#
# USAGE:
#
#
#
#
# NOTE: to use the multival filter you need to specify it in the
# template::list::create in the filters section like this:
#
# -filters {
# filter_name {
# label "Filter Label"
# type multival
# values { {first_value 1 } {second_value 2} }
# where_clause { filter_where_cluse }
# }
# }
# - The receiving page variable must be of the type :multiple
# since the filter sends the values in the following way:
# filter_name=filter_value&filter_name=filter_value&....&extra_variables=extra_values
%>
