I try to figure out how to force slider's buttons to move it instead of normal sliding, but keeping the checkbox filter still working by proper way.

When I set buttons to move slider then filter doesn't work the way it should. The problem is coming out when i change slider code from: values: [10000], to: value: 10000.

Here's my code and jsfiddle example with properly working filter and not working buttons (only slider + checkbox filtering works in that example to show how I need to filter products). https://jsfiddle.net/7er9sxzq/

I'm looking for any help to make it works.

CSS: 

body { font-family:'Arial'; color:#646464; }        
    .continents-wrap { float:left; width:20%; margin:0 5% 0 0; padding:0; }     
    .tabela-wrap { float:left; width:50%; margin:0 5% 0 0; padding:0; position:relative; }  
    .tabela { float:left; width:50%; }
    .tabela div { float:left; width:90%; height:68px; line-height:68px; padding:0 5%; background:#eee; margin:0 0 1px; position:relative; } 
    .number {font-size:12px;}

Is this the intended functionality?

$(document).ready(function(){
  // cache ref to all checkbox elements
  var checkboxes = $('input:checkbox'),
      // cache ref to results
      results = $('#results'),
      // cache ref to our list
      listItems = $('.tabela > li'),
      // cache amount ref
      amount = $('#amount'),
      // collection of selected checkbox elements
      selectedItems = [],
      // slider config
      slideOptions = {
        min: 500,
        max: 100000,
        step: 500,
        values: [10000],
        slide: function(event, ui) {
          amount.val(ui.values[0] + " USD");
        },
        change: function(event, ui) {
          updateList();
        }
      };
      
  // render our slider      
  var slider = $("#price").slider(slideOptions);
  
  amount.val($("#price").slider("values", 0) + " USD");
  
  checkboxes.on('change', function(){
    var id = this.id;

    if(this.checked){
      // push the element vs the value
      selectedItems.push(this.value);
    }else{
      // remove items on uncheck
      selectedItems.splice(selectedItems.indexOf(this.value), 1);
    }

    updateList();
  });

  var updateList = function(){
    // create map of values for joining
    var selectedItemsValues = selectedItems.sort().join(' '),
        // min value
			  minPrice = slider.slider('values', 0);
    
    // filter list items         
    listItems.hide().filter(function(){
      // get data attributes
      var data = this.dataset;
      // restrict list to price band and selections
      return Number(data.price) >= minPrice && (selectedItems.length ? data.category.includes(selectedItemsValues) : true);
    })
    .show();

    // count visible li only
    var total = $('.tabela li:visible').length;

    if(total === 0){
      results.html('We did not find any matches.');
    }else{
      results.html('We found ' + total + (total === 1 ? ' match' : ' matches' ) + '!');
    }
  }
  
  $('.sliderButtons').click(function() {
    var step = Number(this.dataset.step),
        value = slider.slider('values')[0];
        
      value += step;

      slider.slider('values', 0, value);

      amount.val(value + " USD");

      updateList();
  });

I solve that problem by myself. I have changed code of slider to make it works.

I changed part of JS:

function filterPrice(products) {
  let minP = $("#price").slider("value");

  return products.filter(function() {
    let value = parseInt($(this).data("price"), 10);
    return !(value < minP);
  });
}
