Sample HTML:
<select class="b" filter="true">
<option>Launchpad</option>
<option>Google Chrome</option>
<option>Coda 2</option>
<option>Github for Mac</option>
<option>Adobe Photoshop CS6</option>
</select>
You can use the "filter" attribute, set to "true" like in the sample, to include a text input in your select to filter the options.
Sample jQuery:
$('select.b').emmselect("Default title defined : )");
In this sample I used a default title. If the first option element of the select is in blank this text be used as the title.
And that's all.
