Iam trying to use the Filterable feature for my post grid, but it's just not working excepts the "All" tab. I have properly set category for all of my post. I also see the category tab on my blog page, but when I click over them ... nothing happenes, nothing is filtered.
I also want to change the background and text color of the tabs and size of the tabs, but I cannot find where to put the CSS code for that. So please help me also with this.
