<h2>Tips</h2>
<ol>
<li>Always make your <code>a</code> and <code>button</code> in display block</li>
<li>Style with <code>[aria-expanded="true|false"]</code> don't override the script to add an active class</li>
<li>Use an ID <code>$("#id").accessibleMenu()</code> not a class <code><s>$(".class").accessibleMenu()</s></code></li>
</ol>
<h2>Browser support</h2>
<p>All modern browsers and IE >=9.</p>
