Can't get styles to dynamic content

Question

I'm facing strange behaviour: bootstrap somewhat works on my pages, but doesn't style my for forms.

I can see that it loads and all because of buttons, flexbox, grid system. However I can't get it to style forms. Here I'm showing dynamic form with the same code as static form on the same page:

The static form is styled correctly, where as dynamic form is just normalized without any styles applied. I think it is connected with sprockets but having hard time trying to figure it out.

Edit:

<div class="col-md-6">
  <%= form_for(@form) do |f| %>
    <%= render partial: 'shared/req_errors', locals: {scope: "req_statuses.fields"} %>

    <div class="form-group">
      <%= f.label t('.dest') %><br>
      <%= f.select :dest, ReqStatus.dests.collect {|c| [t(".#{c}"), c] } %>
    </div>

    <div class="form-group">
      <%= f.label t('.note') %><br>
      <%= f.text_area :note, cols: 40, placeholder: t('.note-placeholder') %>
    </div>

    <div class="form-group">
      <%= f.label t('.copies') %><br>
      <%= f.select :copies, (1..Request::MAX_NUMBER_OF_COPIES) %>
    </div>

    <div class="actions">
      <%= f.submit t('.submit'), class: "btn btn-primary" %>
    </div>

  <% end %>

Answer 1

I think you forgot to apply CSS for your dynamic form controls. Try adding form-control class to all of the controls in your form would help.
