<%= f.input :skill_list, input_html: { class: 'multiple-input', multiple: "multiple" }, collection: @profile.skill_list %>

app/assets/application.js

$(document).ready(function() {
  $('.multiple-input').each(function() {
    $(this).select2({
      tags: true,
      tokenSeparators: [','],
      theme: 'bootstrap',
      placeholder: 'Separated by comma'
      });
    });
});

also in apps/controllers/profiles_controller.rb I added strong params

def profile_params
  params.require(:profile).permit(:name, skill_list: [])
end
