-        <img alt="" class="example-page-example-icon" src="../../../images/pattern-combobox.svg">
-        <p>
-          The following example implementation of the <a href="../combobox-pattern.html">Combobox Pattern</a> demonstrates a single-select combobox widget that is functionally similar to an HTML <code>select</code> element.
-          Unlike the editable combobox examples, this select-only combobox is not made with an <code>&lt;input&gt;</code> element, and it does not accept freeform user input.
-          However, like an HTML <code>&lt;select&gt;</code>, users can type characters to select matching options.

-        <h2>Accessibility Features</h2>
-        <p>While the functionality and user experience of this example are nearly equivalent to an HTML <code>select</code> element with the attribute <code>size="1"</code>, the following differences in behavior are implemented to improve both accessibility and general usability.</p>
-        <ol>
-          <li>
-            If the combobox is collapsed and the user types printable characters, the listbox is displayed and receives accessibility focus via <code>aria-activedescendant</code>.
-            This enables users to perceive the presence of the options, and enables assistive technology users to comprehend the size of the list of options.</li>
-          <li>
-            Navigating the list of options does not set the value of the input.
-            This gives screen reader users, who need to navigate among the options to perceive them, the ability to explore options without losing the current value of the input.
-            The value is set when users press <kbd>Space</kbd>, <kbd>Enter</kbd>, or <kbd>Tab</kbd>, or when focus moves out of the combobox.
-            The current value is retained if the listbox is closed with <kbd>Escape</kbd> or if the user collapses the list by clicking the input.
-          </li>
-          <li>
-            Browsers do not manage visibility of elements referenced by <code>aria-activedescendant</code> like they do for elements with focus.
-            When a keyboard event changes the active option in the listbox, the JavaScript scrolls the option referenced by <code>aria-activedescendant</code> into view.
-            Managing <code>aria-activedescendant</code> visibility is essential to accessibility for people who use a browser's zoom feature to increase the size of content.

-        <p>
-          The example combobox on this page implements the following keyboard interface.
-          Other variations and options for the keyboard interface are described in the <a href="../combobox-pattern.html#keyboard_interaction">Keyboard Interaction section of the combobox pattern.</a>
