Dropdown button styles are different

[fareez-ahamed]

I was trying to create a dropdown button and it looks unusual

Here is my code with angular js and angular-bootstrap...

<div class="btn-group" dropdown>
    <button type="button" class="btn btn-primary dropdown-toggle" dropdown-toggle>Button dropdown <span class="caret"></span>
    </button>
    <ul class="dropdown-menu" role="menu">
        <li ng-repeat="value in options">
            <a>{{value}}</a>
        </li>
    </ul>
</div>

But the flat-ui site shows the dropdown like this,
