Using {{link-to}} with Bootstrap requires some extra work.
Bootstrap expects
<li> <a> </a> <li>
Additionally bootstrap expects a class="active" attribute on the <li>
Ember.js will mark the class="active" on the <a> when you use {{link-to}}
This will break the boostrap styling.
You can use the below ember add-on to make this easier, essentially it introduce a new component {{active-link}}
You use {{active-link}} instead of <li>
<ul class="nav nav-tabs" role="tablist"> {{#active-link}} {{#link-to "foo" }}Foo{{/link-to}} {{/active-link}} {{#active-link}} {{#link-to "bar" }}Bar{{/link-to}} {{/active-link}} </ul>
