Hi there,
It’s not possible without modifying the theme js file. You can find it in /js/functions.js.php line 436-439:
returnSize: function() {
var itemColumns = 1, windowWidth = $j(window).width();
return windowWidth >= 380 && windowWidth < 480 ? itemColumns = 2 : windowWidth >= 480 && windowWidth < 768 ? itemColumns = 2 : windowWidth >= 768 && windowWidth < 1160 ? itemColumns = 3 : windowWidth >= 1160 && windowWidth < 1640 ? itemColumns = 4 : windowWidth >= 1640 && windowWidth < 2100 ? itemColumns = 5 : windowWidth >= 2100 && (itemColumns = 6), itemColumns;
},
That function decides how many columns based on the window width.
You can change the effect opacity with the following css, add it to the custom css box within theme options and alter the values:
.portfolio-items:hover > li {
filter:alpha(opacity=20)!important;
-moz-opacity: 0.2!important;
opacity: 0.2!important;
}
