Dear all I want to create two select_tag in view, the second select_tag will depend on the first select_tag values. i.e. If the first select_tag selected AHN, then the second have value [CPS,HMS,MBS,BBS] for selection. If the first select_tag selected NDH, only [ABS,CPS] is available in second select_tag. I have no idea how to implement this. Please give me some advices. Thank you. tables column_1 column_2 AHN CPS AHN HMS AHN MBS AHN BBS NDH ABS NDH CPS PWH CPS PWH MBS PWH CRS enquiries controller @column_1= Table.find(:all).collect {|x| [x.column_1, x.column_1]}.uniq view/enquiries <% form_tag do %> <%= select_tag(:column_1, options_for_select(@column_1)) %> <%= select_tag(:column_2, #How to do here?) %> <%= submit_tag "search" %> <% end %> Many thanks Valentino -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
