#nav_bar(name = nil, html_attributes = {}, options = {}, &block) ⇒ Xebec::NavBarRenderer

If called in an output expression (“<%= navbar %>” in ERB or “=navbar” in HAML), renders the navigation bar.

If called with a block, yields the underlying NavBar for modification.

Examples:

<%= navbar :tabs %>
# => <ul class="navbar tabs">...</ul>
<% navbar do |nb|
  nb.nav_item :home
  nb.nav_item :faq, pages_path(:page => :faq)
end %>
