Добрый день!

Есть фильтр на основе Isotope. В нем мне необходимо добавить выпадающий список со значениями. По отдельности, все отлично работает, а объединить все вместе не получается.

Исходный скрипт фильтра:

// External js: jquery, isotope.pkgd.js, bootstrap.min.js, bootstrap-slider.js
$(document).ready( function() {

  var buttonFilters = {};
  var buttonFilter = '*';
  var rangeFilters = {
      'height': {'min':150, 'max': 185},
      'weight': {'min':50, 'max': 90}
    };

  // Initialise Isotope
  var $grid = $('.grid').isotope({
    itemSelector: '.item',
    layout: 'masonry',
    filter: function() {
      var $this = $(this);
      var height = $this.attr('data-height');
      var weight = $this.attr('data-weight');
      var isInHeightRange = (rangeFilters['height'].min <= height && rangeFilters['height'].max >= height);
      var isInWeightRange = (rangeFilters['weight'].min <= weight && rangeFilters['weight'].max >= weight);
      return $this.is( buttonFilter ) && (isInHeightRange && isInWeightRange);
    }
  });

  // Initialise Sliders
  var $heightSlider = $('#filter-height').slider({ tooltip_split: true, min: 130,  max: 220, range: true, value: [150, 180] });
  var $weightSlider = $('#filter-weight').slider({ tooltip_split: true, min: 40,  max: 150, range: true, value: [50, 90] });

  function updateRangeSlider(slider, slideEvt) {
    console.log('Current slider:' + slider);
    var sldmin = +slideEvt.value[0],
        sldmax = +slideEvt.value[1],
        filterGroup = slider.attr('data-filter-group'),
        currentSelection = sldmin + ' - ' + sldmax;

      slider.siblings('.filter-label').find('.filter-selection').text(currentSelection);

      console.log('Filtergroup: '+ filterGroup);
      rangeFilters[filterGroup] = {
        min: sldmin || 0,
        max: sldmax || 100000
      };
      $grid.isotope();
  }

  $heightSlider.on('slideStop', function(slideEvt){
    var $this =$(this);
    updateRangeSlider($this, slideEvt);
  });
  $weightSlider.on('slideStop', function(slideEvt){
    var $this =$(this);
    updateRangeSlider($this, slideEvt);
  });

  $('.filters').on( 'click', '.btn', function() {
    var $this = $(this);
    var $buttonGroup = $this.parents('.btn-group');
    var filterGroup = $buttonGroup.attr('data-filter-group');
    buttonFilters[ filterGroup ] = $this.attr('data-filter');
    buttonFilter = concatValues( buttonFilters ) || '*';
    console.log( buttonFilter )
    $grid.isotope();
  });

  $('.btn-group').each( function( i, buttonGroup ) {
      var $buttonGroup = $( buttonGroup );
      $buttonGroup.on( 'click', '.btn-filter', function() {
          $buttonGroup.find('.is-checked').removeClass('is-checked');
          $(this).addClass('is-checked');
      });
  });
});

function concatValues( obj ) {
  var value = '';
  for ( var prop in obj ) {
    value += obj[ prop ];
  }
  return value;
}

Скрипт который необходимо добавить

var buttonFilters = {};

$('.filters').on( 'change', function( event ) {
  var $select = $( event.target );
  // get group key
  var filterGroup = $select.attr('data-filter-group');
  // set filter for group
  buttonFilters[ filterGroup ] = event.target.value;
  // combine filters
  var filterValue = concatValues( buttonFilters );
  // set filter for Isotope
  $grid.isotope({ filter: filterValue });

Исходный HTML

Добавляемый скрипт и HTML

var buttonFilters = {};

$('.filters').on( 'change', function( event ) {
  var $select = $( event.target );
  // get group key
  var filterGroup = $select.attr('data-filter-group');
  // set filter for group
  buttonFilters[ filterGroup ] = event.target.value;
  // combine filters
  var filterValue = concatValues( buttonFilters );
  // set filter for Isotope
  $grid.isotope({ filter: filterValue });

			<div class="col-sm-4">
				<span class="filter-label">ColorMY:</span>
				<select class="btn-group" data-filter-group="colormy">
				  <option value="">any</option>
				  <option value=".red">red</option>
				  <option value=".blue">blue</option>
				  <option value=".yellow">yellow</option>
				</select>
			</div>

Понимаю, что изменить необходимо нижеприводимый код, но как не знаю.

  $('.filters').on( 'click', '.btn', function() {
    var $this = $(this);
    var $buttonGroup = $this.parents('.btn-group');
    var filterGroup = $buttonGroup.attr('data-filter-group');
    buttonFilters[ filterGroup ] = $this.attr('data-filter');
    buttonFilter = concatValues( buttonFilters ) || '*';
    console.log( buttonFilter )
    $grid.isotope();
  });

Кто знает, подскажите пожалуйста. В интернете ничего похожего не нашел.
Заранее спасибо.
