The Quiet Station 12

crud_record renders the record as a definition list with the same type-aware cells as the table. The column picker is reusable here too: crud_column_picker @book (the gear, top-right) submits ?cols= to this page, and crud_record @book, picked_columns: @visible narrows the list to match — same mechanism as the table, no JS to open. Below it, an embedded reviews collection is static (query: :static). The URL is the book's slug (identify_by :slug).

@visible = CrudComponents.selected_columns(params)   # the picker's ?cols=, for crud_record (persist it if you like)

<%= crud_column_picker @book %>                                  <%# the gear, reusable outside a table %>
<%= crud_record @book, picked_columns: @visible %>  <%# honors the picker's selection %>
