jQuery Sorting results of dropdown and checkbox filters

I have a list of items that are supposed to be sorted by tag and by country. I have a list of checkboxes for the tags and a form with a dropdown for the country.

So far they both work properly, however I can't figure out how to let them both work together. When a country is selected only the items with the country and the checkbox tags chosen should be shown.

Here's what I have so far: - fiddle

$(".filter-options :checkbox").click(function() 
    {
        $(".card-col .card-col-item").hide();
        $(".filter-options :checkbox:checked").each(function() 
        {
           $("." + $(this).val()).fadeIn();
        });
       
        if($('.filter-options :checkbox').filter(':checked').length < 1) 
        {
             $(".card-col .card-col-item").fadeIn();
        }
});


$( ".event-type-select" ).change(function() {
  var selectedEventType = this.options[this.selectedIndex].value;
  if (selectedEventType == "all") {
    $(".card-col .card-col-item").show(function(){$(this).removeClass( "country" );});
      } else {
        $(".filter-options :checkbox").removeAttr("checked");
        $(".card-col .card-col-item").hide(function(){$(this).removeClass( "country" );});
        $('.card-col .card-col-item[data-eventtype="' + selectedEventType + '"]').show(function(){$(this).addClass( "country" );});
  }
});
     

$(".reset-filter").click(function() 
    {
    $(".filter-options :checkbox").removeAttr("checked");
            $(".card-col .card-col-item").show(function(){$(this).removeClass( "country" );});
    });

The HTML:


<div class="filter-wrapper">
        <h3>Filter Items</h3>
        <button class="reset-filter">
          reset
        </button>
          <ul class="filter-options">
             
            <li class="filter-list"><div><input type="checkbox" value="tag1" data-filter_id="tag1"> Our Solutions</div></li>
            
            <li class="filter-list"><div><input type="checkbox" value="tag2" data-filter_id="tag2"> Service categories</div></li>
            
          </ul>

Combine these into one change event handler.

For the tags I make an array of the checked checkbox values and Array#some() for a variable tagsMatch and another variable for countryMatch inside a jQuery filter() and return an expression that both are true

const $checks = $(".filter-options :checkbox"),
$sel = $('.event-type-select'),
$items = $('.card-col-item')


$checks.add($sel).change(function(){
    const tagsArr = $checks.filter(':checked').map((i, el)=> el.value).get(),
          country = $sel.val();
    // hide all items then filter the ones to show
    $items.hide().filter(function(){
         const $item = $(this),
                eType = $item.data('eventtype'),
                tagsMatch = !tagsArr.length  || tagsArr.some(tag => $item.hasClass(tag)),
                countryMatch = country === 'all' || country === eType;
         
         return tagsMatch && countryMatch;
    }).show()

})
