Изотопная сетка Bootstrap

Question

Я работаю над одной страницей этого сайта: http://simonenicosia.com/isotopeTest/

Я хотел бы достичь этого результата сетки:

но что-то не так. Я не знаю, касается ли это размерности col или параметров js...

portfolio.js

  var container = jQuery('#portfolio-grid');
  container.isotope({
    itemSelector: '.portolio-item',
    masonry: {
      columnWidth: 100
    }
  });

HTML

  <div id="portfolio-grid" class="portfolio-grid">

          <!-- For Project Expander -->

        </div>

Я использую Bootstrap 3 + Isotope v1.5.25

Answer 1

Решено! Использование режима упаковки https://packery.metafizzy.co/

  var container = jQuery('#portfolio-grid');
  container.isotope({
    itemSelector: '.portolio-item',
    packery: {
      gutter: 0
    }
  });

HTML

  <script src="assets/js/portfolio.js"></script>
  <script src="assets/js/isotope.pkgd.min.js"></script>
  <script type="text/javascript" src="assets/js/packery-mode.pkgd.min.js"></script>
