This was the first SO page for a DDG search with 'rails collection_check_boxes bootstrap', but it's not about Bootstrap, but here is a solution for Bootstrap 4 anyways.

This works with plain Rails and Bootstrap 4, no gem required. collection_check_boxes is a plain Rails method.

  .form-group
    =f.label :industry_interest
    %br
    =f.collection_check_boxes :industry_interest, Industry.all, :id, :name do |cb|
      =cb.check_box 
      =cb.label
      %br

or

  .form-group
    =f.label :industry_interest
    =f.collection_check_boxes :industry_interest, Industry.all, :id, :name do |cb|
      .form-check
        =cb.label class: 'form-check-label' do
          =cb.check_box class: 'form-check-input'
          =cb.text 

They look identical.
