The BootstrapBreadcrumbsBuilder is a Bootstrap compatible breadcrumb builder. It provides basic functionalities to render a breadcrumb navigation according to Bootstrap’s conventions.

BootstrapBreadcrumbsBuilder accepts a limited set of options:

  • separator: what should be displayed as a separator between elements

You can use it with the :builder option on render_breadcrumbs:

<%= render_breadcrumbs :builder => ::BootstrapBreadcrumbsBuilder, :separator => "&raquo;" %>

Note: You may need to adjust the autoload_paths in your config/application.rb file for rails to load this class:

config.autoload_paths += Dir["#{config.root}/lib/"]
