This was super annoying so i decided to write it down.

I needed to add some data attributes to a simple_form input(f.input :people, as: :select) and also maintain the bootstrap classes

Here's how i solved it:

<%= f.input :car_id, label: 'Select a Car' do %>
    <%= f.select :car_id, @cars.map { |car| [car.name, car.id, {'data-car-price' => car.current_price}] }, {include_blank: true}, {class: 'form-control'} %>
&lt;% end %&gt;
