I read about the observe field select. Two things: Every post I see determines a second select based on the first select. What I am trying to do is based on the first select either display a second select or display a text field(this will depend on the first select value) I tried to use the observe field and I am not sure of two things: the action=> 'funtion' Do I need to create in the controller any function and if yes what? basically if there is a change in the select, I want to check the value if it equals 5, display a second select, if not display text field. Also what does the parameter :with do? The :update=> "myfield name" this field should be the second select name and then how to I display the text field instead? -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
