Angularjs bootstrap dropdown not working

NOTE: Most answers here are outdated! The main issue is that the dropdown directive is not available as a class anymore, but only as an attribute, and that it has been renamed to uib-dropdown.

I was stuck here for a while, but changing the class into an attribute worked as a charm.

Also, you need to use the ‘uib-‘ prefix for each directive instead of plain names.

<li uib-dropdown>
    <a uib-dropdown-toggle>a<span class="caret"></span></a>
    <ul uib-dropdown-menu>
        <li><a ui-sref="a">a</a></li>
        <li><a ui-sref="b">b</a></li>
        <li><a ui-sref="c">c</a></li>
        <li><a ui-sref="d">d</a></li>
    </ul>
</li>

(And of course, make sure you did not forget to include the ui.bootstrap module in your app.)

var app = angular.module('App', ['ui.router','ui.bootstrap']);
