title: HTML/PHP one line dropdown list multiple selection
body: <p>does anyone know a way to create a dropdown list as in a select statement that allows multiple selections but can display on one line. Adding the multiple="multiple" option causes it to display on as many lines as there are options which is not suitable for this project's layout  Css and/or javascript would be fine however, hoping to avoid js frameworks.  Thinking something with onclick event to show the standard multi-line dropdown box might work but not sure how to implement.</p>
  
  <p>Following displays on several lines.</p>
  
  <pre><code> &lt;select name="items[ ]" multiple="multiple"&gt;
      &lt;option value="item1"&gt;item1&lt;/option&gt;
       &lt;option value="item2"&gt;item2&lt;/option&gt;
      &lt;option value="item2"&gt;item2&lt;/option&gt;&lt;/select&gt;
  </code></pre>
