Creator of Codiqa here. This is jQuery Mobile behavior that you can disable by telling it to not enhance that form element:
<label for="foo">
<select name="foo" id="foo" size="5" data-role="none">
<option value="a">A</option>
<option value="b">B</option>
<option value="c">C</option>
</select>
We don't have a way to do this right inside of Codiqa yet, but it would be easy enough to add.
