It should be done using javascript. Or if you want to get the values of second dropdown from server then you have to use AJAX.

I understood the question but I don’t know that why I am unable to answer this. I think you should provide me the HTML code which is shown in page source after the page is loaded. It’s embarrassing for me that I am unable to understand the code in your html.erb file.
