Can you change CSS for view in Controller in Rails?

I have a view (let's call it View #1) that allows the user to select a certain table to view using a dropdown menu on a form. That parameter is then passed to my controller. What I want to do is get my controller to take that parameter and use it to change the visibility of elements on the view it directs to (View #2).

View #2 has 3 tables. Only one table should be visible at any given time once my method in my Controller runs. Currently, all 3 tables have unique IDs and they have a display:none attribute in the CSS file. So, if the user selects "1" from View #1, I want View #2 to set table 1's display to block and table 2 and 3 to display:none. Can I do this in the Controller or am I required to do this in JavaScript? If I have to do this in JavaScript, how do I pass the parameter value from the controller to the JS function call?

you should probably break out each table into its own partial and only render the one you want to display:

def some_action
  @table_to_show = "table_1"
  # table_1 should be determined by the user's selection from View #1
  # probably something like: @table_to_show = params[:user_selection]
end

and in your view #2:

<%= render @table_to_show %>

which will in turn render the template: _table_1.html.erb

You can use CSS/js, but probably shouldn't for something that is handled at the controller level.
