Drupal Google Store Locator module modification needed

General information for the website: Store locator module
Description of requirements/features: Hi there,

I am pretty new to drupal and don't know much about coding, i've installed Google Store Locator module and it works perfectly. i just want the feature-filter list to be select list instead of checkbox
from this:
http://storelocator.googlecode.com/git/examples/dynamic.html
to this:
http://jsfiddle.net/doktormolle/HKUrf/

this has to be done on the drupal Google Store Locator module

I think the code that prints the checkbox is this
if (a.c.featureFilter) {
a.d = $('');
for (var b = a.get("view").getFeatures().asList(), c = 0, e = b[B]; c < e; c++) {
var i = b[c],
k = $('');
k.data("feature", i);
$("")[G](k)[G](i.getDisplayName()).appendTo(a.d)
}
a.e[G](a.d);
a.d[r]("input").change(function () {
var b = $(this).data("feature"),
c = a.get("featureFilter");
c.toggle(b);
a.set("featureFilter", c);
a.get("view").refreshView()
})
}

the code can be found here
