Nate said 5 months ago on Building a Questionnaire :
Hi David! I'm wondering what would you suggest doing in the case that I would like to render the same

<%= form.text_field :name, placeholder: 'Answer', class: 'form-control' %>

answer field in the long answer div i.e

  <div data-controller="nested-form" data-dynamic-select-target='long'>
     <%= form.fields_for :answers, Answer.new do |answer| %>
       <%= answer.text_field :name, placeholder: 'Answer', class: 'form-control' %>
      <% end %>

I've played with this, but this keeps causing problems since it will submit answer the form everytime with one empty field also. Any suggestions?
