Can anyone point me in a solid direction to create something like this. .. https://codepen.io/MandyMadeThis/pen/dGQxaN I'm trying to convert my joomla blog.php into a filterable page. But, I'm getting stuck. It appears that this example requires an exact match of class but my classes are based on categories and tags and no two are alike. My js jquery is at a noob level. So, i don't even know enough to know what to ask. Would truly appreciate any insights.
