Hello frnds,    I hav 2 select boxes. First select box is populated with all the "distinct states".On selecting a state I want the 2nd selct box to be populated with its corresponding "districts". On selecting the district,I want some data to be displayed for that corressponding district. I am able to display the data on selecting the "district".(using RJS template and partial) But the 2nd select box is always populated with all the districts.It is not populated accoring to the selection of first selectbox. Can you help me in solving this problem?

I'm still new to Rails so pardon me if I misunderstand your issue, but I believe the answer is to use

1) collection_select 2) :onchange
