Add all the extra stuff to your view, but place it all in a div that is hidden. Then unhide that div with javascript when they activate the appropriate control. — Daiku

First of all, PaymentGateway.all is a bad idea. This shouldn't be there in the view but loaded from the controller in an instance variable. Please change that.

One way to do that would be to define a attribute, let us say 'additional_info':

<% PaymentGateway.all.each do |pg| %>
  <%= check_box_tag ..., onclick: "$('#{pg}_info').show(); $('#{pg}_info').siblings().hide();" %>
  ...
<% end %>

<div class="additional_infos">
  <%= f.input :gateway1_info, label: "Gateway" ... %>
</div>
