“Cards” is a custom layout you add — the gem ships only the built-in :table. Drop one partial that receives the same collection presenter (still driven by the :index fieldset) and arrange the markup however you like; the gem still derives the fields, cells, filtering, sorting and actions for you. A card grid has no column headers, so crud_filter takes sort: true to carry the sort picker.

<% collection.records.each do |record| %>
  <div class="card card-body">
    <% collection.fields.each do |f| %><%= collection.cell(f, record) %><% end %>
  </div>
<% end %>

<%= crud_collection @books, fieldset: :index, layout: :cards %>
<%= crud_filter   Book, fieldset: :index, sort: true %>   <%# headerless → carry the sort picker %>
