Did it like this:

if (container.hasClass('hidden')) {
      var containerWidth = container.outerWidth();
      var totalWidth = 0;
      var childrens = container.children();
      var i = 0;
      while (totalWidth < 300) {
        totalWidth += childrens.eq(i).outerWidth(true);
        i++;
      }      
    }
