<p dir="auto">If you use a typeahead drop down menu within a fixed navbar, the dropdown menu is displayed under the navbar. The dropdown is given a z-index of 1000 whilst the fixed navbar is 1030.</p>
<p dir="auto">The typeahead menu pops up below elements with the <code class="notranslate">.navbar-fixed-top</code> class.  Adding <code class="notranslate">z-index:1030</code> to <code class="notranslate">up.typeahead</code> fixed the problem for me.</p>
