Isotope & Media Queries

Question

Absolutely pulling my hair out on this one. There seems to be no black and white solution offered on GitHub - which is strange, since it seems like a fairly simple concept. Perhaps I just don't get it.

Basically, I am trying to create a fluid and responsive portfolio - using Isotope to filter the items. The filtering works fine, the 4 columns are totally fluid and everything looks great when you resize the window.

HOWEVER, for mobile and tablet layouts, I simply need to adapt from a 4-column layout to a 2-column layout.

I tried this:

$(window).load(function(){

    var $container = $('#thumbs');
    $container.isotope({
        filter: '*',
        animationOptions: {
            duration: 750,
            easing: 'linear',
            queue: false,
       },
    });

    // initialize Isotope
    $container.isotope({
      // options...
      resizable: false, // disable normal resizing
      // set columnWidth to a percentage of container width
      masonry: { columnWidth: $container.width() / 4 },
    });

    // update columnWidth on window resize
    $(window).smartresize(function(){
        $container.isotope({
            // update columnWidth to a percentage of container width
            masonry: { columnWidth: $container.width() / 4 }
        });
    });

// My attempt at using media queries to change 'columnWidth'
    $(window).resize(function() {
        var width = $(window).width();
        if (width < 768) {
            $container.isotope( {
                // update columnWidth to half of container width
                masonry: { columnWidth: $container.width() / 2 }
            });
        }
    });
});

Didn't work :(

Any help would be much appreciated.

This should work to set your number of columns. Then you just divide with columns.

var columns;

// set column number
setColumns();

// rerun function when window is resized 
$(window).on('resize', function() {
  setColumns();
});

// the function to decide the number of columns
function setColumns() {
  if($(window).width() <= 768) {
    columns = 2;
  } else {
    columns = 4;
  }
}
