<li>Otherwise, the value of the <code>combobox</code> is represented by its descendant elements and can be determined using the same method used to compute the name of a <rref>button</rref> from its descendant content.</li>

</ul>

<pre class="example highlight">

&lt;input type="text" id="tag_combo"

role="combobox" aria-autocomplete="list"

aria-haspopup="listbox" aria-expanded="true"

aria-controls="popup_listbox" aria-activedescendant="selected_option"&gt;

&lt;li role="option"&gt;Zebra&lt;/li&gt;

&lt;li role="option" id="selected_option"&gt;Zoom&lt;/li&gt;

&lt;/ul&gt;
