// on function call autocreate data agnostic filters
function createFilter(name, data) {
  var items = [];
  for (i in data) {
    items.push(data[i][name]);
  }
  var list = items.filter(uniqueValues);
  list.sort();
  
  $.each(list, function(i, item) {
    $('#filter-' + name).append($('<option class="options">' + item + '</option>').val(item));
  });
  
  // return only unique values
  function uniqueValues(value, index, self) {
    return self.indexOf(value) === index;
  }
}
