<b>Client</b><br /> <%= select_tag 'clients', options_for_select( [[' ','1'], ['aaaa','2'], ['daemon','3'],['nortel','4'],['telefonica','5'],['local','6'],['otro','7']] ), { :multiple => true, :size =>4 } %> </p>
Instead of using the ['...', '.'] code I would like to use a method of a list of clients that I have.
