def items
  @items ||= list.filter_map do |action|
    next if action.name == :show && action.derived? && @suppress_show
    next unless action.permitted?(permission_context, @subject)

    path = RouteResolver.action_path(view, action,
                                     record: kind == :row ? @subject : nil,
                                     model: @model, owner: @owner)
    next unless path

    Item.new(action: action, path: path)
  end
end

#joinable? ⇒ Boolean

Bootstrap btn-group only renders cleanly when every child is a direct ‘.btn`. A non-GET action is a button_to form, which breaks the group’s edge radii — so we only join when all actions are GET links.

Returns:

  • (Boolean)
