Navbars and Navigation Lists

Leather has a helper method that lets you generate Bootstrap navbars and navigation lists. For example, you can render a navbar with the following code:

= navbar "Leather", root_url, container_mode: :with, class: "navbar-inverse" do
  = nav_list do
    = dropdown_nav_item 'Lorem', '#' do
      = nav_item 'Ipsum', '#'
      = nav_item 'Dolor', '#'
      = nav_item 'Sit', '#'
    = nav_item 'Home', '#'
    = nav_item 'Dolor', '#'
    = nav_item 'Sit', '#'
  = nav_list class: 'navbar-right' do
    - if user_signed_in?
      = nav_item 'Sign Out', destroy_user_session_path, method: :delete
    - else
      = nav_item 'Sign In', new_user_session_path
      = nav_item 'Sign Up', new_user_registration_path`

With a little extra setup, you can manage the "active" nav_item easily. First, in your controller, add this:

set_tab :name, :namespace

This takes the same options as a before_filter, so you can restrict it to certain actions:

set_tab :name, :namespace, only: [:index, :show]

When you generate a nav_item or a dropdown_nav_item, you can identify the link's name and namespace:

= nav_item 'Home', '#', nav_id: [:name, :namespace]
